The output voltage of a power supply is normally distributed with mean 12 V and standard deviation 0.11 V. If the upper and lower specifications for voltage are 12.15 V and 11.85 V respectively, what is the probability that the power supply selected at random will confirm to the specifications on voltage?
Answers
Answer:
82.62%
Explanation:
The z score is a score used in statistics to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
\(z=\frac{x-\mu}{\sigma} \\\\where\ x=raw\ score,\mu=mean\ and\ \sigma=standard\ deviation.\\\\Given \ that\ \mu=12V, \sigma=0.11V.\\\\For\ x<12.15V:\\\\z=\frac{12.15-12}{0.11} =1.36\\\\For\ x>11.85V:\\\\z=\frac{11.85-12}{0.11} =-1.36\\\\\)
From the normal distribution table, P(11.85 < x < 12.15) = P(-1.36 < z < 1.36) = P(z < 1.36) - P(z < -1.36) = 0.9131-0.0869 = 0.8262 = 82.62%

Static Friction and Kinetic Friction
Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.
There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.
Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.
Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.
when measuring expected voltage or current, select a scale that is ________ on a multimeter.
Answers
When measuring expected voltage or current, select a scale that is equal to or greater than the expected value on a multimeter.
Selecting the appropriate range or scale on a multimeter is important to ensure accurate and safe measurements. If the range or scale is set too low, the multimeter may not be able to measure the full value of the voltage or current being measured, which can result in an inaccurate reading or even damage to the multimeter.
On the other hand, if the range or scale is set too high, the multimeter may not be able to detect the expected voltage or current level, which can also result in an inaccurate reading. Therefore, it's important to select the appropriate range or scale on a multimeter that is equal to or greater than the expected value to ensure accurate and safe measurements.

An ideal vapor-compression refrigeration cycle that uses refrigerant-134a as its working fluid maintains a condenser at 800 kPa and the evaporator at −12°C. Determine this system's COP and the amount of power required to service a 150 kW cooling load.
Answers
Answer:
COP = 4.846
Explanation:
From the table A-11 i attached, we can find the entropy for the state 1 at -12°C.
h1 = 243.3 KJ/Kg
s1 = 0.93911 KJ/Kg.K
From table A-12 attached we can do the same for states 3 and 4 but just enthalpy at 800 KPa.
h3 = h4 = hf = 95.47 KJ/Kg
For state 2, we can calculate the enthalpy from table A-13 attached using interpolation at 800 KPa and the condition s2 = s1. We have;
h2 = 273.81 KJ/Kg
The power would be determined from the energy balance in state 1-2 where the mass flow rate will be expressed through the energy balance in state 4-1.
W' = m'(h2 - h1)
W' = Q'_L((h2 - h1)/(h1 - h4))
Where Q'_L = 150 kW
Plugging in the relevant values, we have;
W' = 150((273.81 - 243.3)/(243.3 - 95.46))
W' = 30.956 Kw
Formula foe COP is;
COP = Q'_L/W'
COP = 150/30.956
COP = 4.846
The one end of a hollow square bar whose side is 0. 1 in with 0. 01 in thickness is under a tensile stress 102,500 psi and the other end is connected with a U bracket using a pin. Find the minimum diameter of pin is used. Take σ_all=243 ksi for pin material
Answers
The minimum diameter of the pin is 0.037 inches.
B. The first step in determining the minimum diameter of the pin is to calculate the maximum allowable stress for the pin material, which is given as 243 ksi.
Next, the load on the pin needs to be determined. Since one end of the bar is under a tensile stress of 102,500 psi, this load will be transferred through the pin to the U bracket.
To find the minimum diameter, we need to calculate the area of the pin using the formula A = P / σ_all, where P is the load and A is the area.
The area A can be calculated as P/σ_all = (102,500 psi) / (243 ksi) = 0.042 in^2. Finally, the minimum diameter of the pin can be calculated as d = √(4A/π) = 0.037 inches.

Two types are equivalent if an operand of one type in an expression is substituted for one of the other type, without coercion. There are two approaches to defining type equivalence. Name type equivalence means that two variables have equivalent types if they are defined either in the same declaration or in declarations that use the same type name. Structure type equivalence means that two variables have equivalent types if their types have identical structures.
(a) (4 marks) The Pascal language adopts name type equivalence. Consider the following declarations:
al: array [1..10] of integer;
a2: array [1..10] of integer;
According to name type equivalence, the variables a1 and a2 are considered to have distinct and non-equivalent types. In other words, values of a1 cannot be assigned to a2, and vice versa.
Suggest two ways of defining a1 and a2 so that they have the same type.
(b) (4 marks) On the other hand, structure type equivalence is more lenient. Consider the following declarations:
al: array [1..10] of integer;
a2: array [11..20] of integer;
The types of the variables a1 and a2 are considered to be equivalent, even though they have different names and different subscript ranges. It is because both types have 10 elements of the integer type.
Give two scenarios in which structure type equivalence is undesirable.
Answers
a) Two ways of defining a1 and a2 so that they have the same type: using a type name or using a variable of the same type.
b) Two scenarios where structure type equivalence is undesirable: maintaining/modifying programs with different types but the same structure, and performance issues due to unnecessary creation of identical data structures.
a) Two ways of defining a1 and a2 so that they have the same type:
Using a type name to define a new type, and then using that type for the variables a1 and a2. Type names allow for the creation of new types by specifying their component types and sizes.
Example: type MyArray = array [1..10] of integer; var a1, a2: MyArray;
Using a variable of the same type to declare a2.
Example: var a1: array [1..10] of integer; a2: typeof(a1);
b) Two scenarios in which structure type equivalence is undesirable:
If a program uses different types that happen to have the same structure, bugs might occur when the program is maintained or modified. It's more difficult to make changes to the program when equivalent types are defined using different type names.
When structure type equivalence is used inappropriately, performance may suffer. Because it can lead to the creation of identical data structures, which is unnecessary. It can lead to wasted memory, slow execution, and inefficient use of system resources.

Answers
The horizontal component of a force of 100 kip acting at an angle of 60 degrees with the horizontal axis is 50 kip.
To determine the horizontal component of a force, we use trigonometric functions. In this case, we can use the cosine function to find the horizontal component. The cosine of an angle is defined as the ratio of the length of the adjacent side to the length of the hypotenuse in a right triangle.
In the given scenario, the force of 100 kip can be represented as the hypotenuse of a right triangle, with the horizontal component being the adjacent side. The angle between the force and the horizontal axis is 60 degrees. By using the cosine function, we can calculate the horizontal component as the product of the force magnitude (100 kip) and the cosine of the angle (cos 60 degrees):
Horizontal component \(= 100 kip \times cos(60 \textdegree) = 100 kip \times 0.5 = 50 kip.\)

what is normally the highest short circuit current in residential applications
Answers
Answer:
10,000A
Explanation:
name me brainliest please.
The highest short circuit current in residential applications is typically determined by the utility company and the capacity of the transformer serving the residential area.
In most cases, the short circuit current in a residential application is limited to a few thousand amps, with typical values ranging from 2,000 to 10,000 amps. This is because residential electrical systems are designed to handle relatively low levels of current, typically up to 200 amps for a single-family home.
Short circuit current can occur in residential applications due to a fault in the electrical system, such as a short circuit caused by a damaged wire or overloaded circuit. In such cases, the short circuit current can cause damage to electrical equipment and pose a risk of fire or electrical shock.
To protect against short circuit current, residential electrical systems are typically equipped with overcurrent protection devices, such as fuses or circuit breakers. These devices are designed to interrupt the flow of current in the event of a fault, protecting the electrical equipment and preventing further damage.
Overall, while short circuit currents in residential applications can vary depending on the specific circumstances, they are typically limited to a few thousand amps due to the design and capacity of the electrical system.

What are the differences between bulk deformation processes and sheet metal processes?.
Answers
Bulk deformation processes are applied to achieve large deformation of metal materials, resulting in a change in their overall shape. On the other hand, sheet metal processes primarily affect the surface layers of metal sheets to achieve a specific shape, size, and finish.
This fundamental difference results in several other notable differences between these two processes, which are discussed below.Bulk deformation processes:This process is used to transform the overall shape of metal materials. The material is placed in a die and subjected to high stress and pressure to achieve the desired deformation. This process often involves heating the metal to high temperatures to enhance its ductility. This process is also referred to as "forging" or "forming" processes.
Some of the common bulk deformation processes include:
Forging: This process is applied to metal materials at high temperatures to change their overall shape.
Rolling: This process involves reducing the thickness of a metal material by compressing it between two rollers.
Extrusion: This process is used to produce uniform cross-section shapes and is applied to create pipes, tubes, and other structures.
Sheet metal processes:This process primarily affects the surface of metal sheets, resulting in a specific shape, size, and finish. Sheet metal is thinner than bulk metals, making it easy to shape and deform without heating it. Sheet metal is used in many applications, such as building facades, ductwork, automotive bodies, and machine casings.
Some of the common sheet metal processes include:
Cutting: This process is used to cut a piece of sheet metal to the desired shape and size.
Bending: This process is applied to a sheet metal workpiece to achieve a specific shape.

Find the first-order kinematic coefficient of the gear train. What are the speed and direction of rotation of gear 8? ω,-1200 rev/min 4 15T 44T 33T 36T 487
Answers
The first-order kinematic coefficient of the gear train is 0.028. Gear 8 rotates in the clockwise direction with a speed of 42.86 rev/min.
What is the rotational direction and speed of gear 8 and what is the first-order kinematic coefficient of the gear train?The first-order kinematic coefficient of the gear train is a measure of the efficiency of power transmission through a gear train. It is defined as the ratio of the output speed of the final gear to the input speed of the first gear. In this case, the first-order kinematic coefficient is 0.028, which means that the output speed of gear 8 is only 2.8% of the input speed of gear 4.
To determine the rotational direction and speed of gear 8, we first need to identify the gear ratios for each pair of gears in the train. Starting from gear 4, we have a gear ratio of 44/15, which means that gear 5 rotates at a slower speed than gear 4 but with higher torque. Similarly, the gear ratio between gears 5 and 6 is 33/36, which means that gear 6 rotates at a faster speed than gear 5 but with lower torque.
Finally, we can calculate the speed and direction of rotation of gear 8 by multiplying the gear ratios of all the gears between gear 4 and gear 8. We have:
44/15 * 33/36 * 487/36 = 42.86
This means that gear 8 rotates at a speed of 42.86 rev/min in the clockwise direction.

The displacement of a certain object is described by y(t) = 23 sin 5t, where t is measured in seconds. Compute its period and its oscillation frequency in rad/sec and in hertz
Answers
Answer:
5 rad/sec
0.796 Hz
1.256 seconds
Explanation:
Y(t) = 23sin5t ----1
Y(t) = aSin(w)t----2
w = 5 rad/sec
Then we get the Oscillation frequency from the formula below
w = 2πf
We make f to be the subject of this formula
f = w/2π
f = 5/2*3.24
f = 5/6.28
f = 0.796Hz
From the calculated frequency, we get the period = 1/f
= 1/0.796
= 1.256 seconds
Technician A says that reversing the direction of refrigerant (as with a heat pump system) could be done to provide cabin heat. Technician B says that the amount of energy loss from the traditional drive belt and electric clutch A/C system is too high for hybrid and electric vehicles. Who is correct?
Answers
It can be noted that technician B is correct as amount of energy loss from the traditional drive belt and electric clutch A/C system is too high for hybrid and electric vehicles.
What is energy?Energy simply means the property that is transferred to a body.
In this case, Technician A says that reversing the direction of refrigerant as with a heat pump system could be done to provide cabin heat. This is incorrect because this is done to remove heat.

Two identical bulbs are connected to a 12-volt battery in parallel. The voltage drop across the first bulb is 12 volts as measured with a voltmeter. What is the voltage drop across the other bulb?
Answers
Answer:
12 volts
Explanation:
The voltages across parallel-connected items are identical. (In fact, that's why you can measure the voltage by connecting the voltmeter in parallel with the circuit element.)
The voltage drop across each bulb is 12 volts.

Determine the real roots of f (x) = −0.6x2 + 2.4x + 5.5:(a) Graphically.(b) Using the quadratic formula.(c) Using three iterations of the bisection method to determinethe highest root. Employ initial guesses of xl = 5 and xu = 10.Compute the estimated error εa and the true error εt after eachiteration.
Answers
The three methods used to find the real roots of the function are,
graphically, the quadratic formula, and by iteration.
The correct vales are;
(a) Graphically, the roots obtained are; x ≈ -1.629, and 5.629
(b) Using the quadratic formula, the real roots of the given function are; x ≈ -1.62589, x ≈ 5.62859
(c) Using three iterations, we have; the bracket is \(x_l\) = 5.625, and \(x_u\) = 6.25
Reasons:
The given function is presented as follows;
f(x) = -0.6·x² + 2.4·x + 5.5
(a) The graph of the function is plotted on MS Excel, with increments in the
x-values of 0.01, to obtain the approximation of the x-intercepts which are
the real roots as follows;
\(\begin{array}{|c|cc|}x&&f(x)\\-1.63&&-0.00614\\-1.62&&0.03736\\5.62&&0.03736 \\5.63&&-0.00614\end{array}\right]\)
Checking for the approximation of x-value of the intercept, we have;
\(x = -1.63 + \dfrac{0 - (-0.00614)}{0.0376 - (-0.00614)} \times (-1.62-(-1.63)) \approx -1.629\)
Therefore, based on the similarity of the values at the intercepts, the x-
values (real roots of the function) at the x-intercepts (y = 0) are;
x ≈ -1.629, and 5.629
(b) The real roots of the quadratic equation are found using the quadratic
formula as follows;
The quadratic formula for finding the roots of the quadratic equation
presented in the form f(x) = a·x² + b·x + c, is given as follows;
\(x = \mathbf{ \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}}\)
Comparison to the given function, f(x) = -0.6·x² + 2.4·x + 5.5, gives;
a = -0.6, b = 2.4, and c = 5.5
Therefore, we get;
\(x = \dfrac{-2.4\pm \sqrt{2.4^{2}-4\times (-0.6)\times 5.5}}{2\times (-0.6)} = \dfrac{-2.4\pm\sqrt{18.96} }{-1.2} = \dfrac{12 \pm\sqrt{474} }{6}\)
Which gives
The real roots are; x ≈ -1.62859, and x ≈ 5.62859
(c) The initial guesses are;
\(x_l\) = 5, and \(x_u\) = 10
The first iteration is therefore;
\(x_r = \dfrac{5 + 10}{2} = 7.5\)
\(Estimated \ error , \ \epsilon _a = \left|\dfrac{10- 5}{10 + 5} \right | \times 100\% = 33.33\%\)
\(True \ error, \ \epsilon _t = \left|\dfrac{5.62859 - 7.5}{5.62859} \right | \times 100\% = 33.25\%\)
f(5) × f(7.5) = 2.5 × (-10.25) = -25.625
The bracket is therefore; \(x_l\) = 5, and \(x_u\) = 7.5
Second iteration:
\(x_r = \dfrac{5 + 7.5}{2} = 6.25\)
\(Estimated \ error , \ \epsilon _a = \left|\dfrac{7.5- 5}{7.5+ 5} \right | \times 100\% = 20\%\)
\(True \ error, \ \epsilon _t = \mathbf{\left|\dfrac{5.62859 - 6.25}{5.62859} \right | \times 100\%} \approx 11.04\%\)
f(5) × f(6.25) = 2.5 × (-2.9375) = -7.34375
The bracket is therefore; \(x_l\) = 5, and \(x_u\) = 6.25
Third iteration
\(x_r = \dfrac{5 + 6.25}{2} = 5.625\)
\(Estimated \ error , \ \epsilon _a = \left|\dfrac{5.625- 5}{5.625+ 5} \right | \times 100\% = 5.88\%\)
\(True \ error, \ \epsilon _t = \mathbf{\left|\dfrac{5.62859 - 5.625}{5.62859} \right | \times 100\%} \approx 6.378 \times 10^{-2}\%\)
f(5) × f(5.625) = 2.5 × (0.015625) = 0.015625
Therefore, the bracket is \(x_l\) = 5.625, and \(x_u\) = 6.25

What is the purpose of making internal resistance of milli-ammeter very low?A) High accuracy.B) Minimum voltage drop across meter.C) Maximum voltage drop across meter.D) High sensitivity.
Answers
Answer:
B) Minimum voltage drop across meter
Explanation:
An ammeter is a measuring instrument device that is used to measure small currents flowing through a circuit in milli-ampere. The internal resistance of the milli ammeter is very low so that there would be a minimum voltage drop across the meter causing a minimum effect of the current in the circuit, this results to a measurement closer to the original value. If a high resistance is place, there would be large voltage drop therefore the current measured would be lesser than the original value.
