Answer:

50 N ---->

Explanation:

Opposing sides get subtracted so~

25-25 cancels out to zero so there is 0N

100 -50 equals 50 N ->

Along vertical direction, net force is 0N and along horizontal direction, the net force is 50N directed towards right.

To determine the answer, we need to know about how to calculate the net force.

To determine the net force along any direction, we have to sum all the forces that are directed along that direction.

Forces that directed along vertical direction are

Net force = 25 N (vertically upward) + 25 N (vertically downward)

                = 25 N - 25N = 0N

Here, we take '+ sign' for upward direction and '- sign' for downward direction.

Forces that directed along horizontal direction are

Net force= 100 N towards right + 50 N towards left

               = 100N - 50N

               = 50 N (towards right)

Here, we take '+ sign' for horizontally right direction and '- sign' for horizontally left direction.

Thus, we can conclude that 0 N is the net force along vertical direction and 50 N is the net force along horizontal direction.

Answer:

V=34.2 m/s

Explanation:

Given that

Height , h= 54 m

Horizontal distance , x = 35 m

Given that , the ball is thrown horizontally , therefore the initial vertical velocity will be zero.

In vertical direction :

We know that

\(V^2_y=U^2_y+2 g h\)

Now by putting the values in the above equation we got

\(V^2_y=U^2_y+2 g h\)

\(V^2_y=0^2+2\times 9.81 \times 54 \)

Assume \(g= 9.81 m/s^2\)

Thus

\(V^2_y=1059.48 \)

\(V_y=\sqrt{1059.48}\ m/s\)

\(V_y=32.54 m/s\)

We also know that

\(V_y=U_y+ g\times t\)

\(32.54=9.81\times t\)

\(t=\dfrac{32.54}{9.81}=3.31\ s\)

In horizontal direction :

\(x=U_x\times t\)

\(U_x=\dfrac{35}{3.31}=10.54\ m/s\)

Thus the resultant velocity

\(V=\sqrt{V^2_y+U^2_x}\)

\(V=\sqrt{32.54^2+10.54^2}=34.2\ m/s\)

V=34.2 m/s

Therefore the velocity will be 34.2 m/s.

The average velocity for the time period from t = 2 to t = 3 is -36 feet/second.

To find the average velocity for the given time period, we need to calculate the change in position (Δy) divided by the change in time (Δt).

Given the height function y = 44t - 16t^2, we can find the average velocity for each time period as follows:

(a) Time period: t = 2 to t = 3

To find the change in position (Δy), we evaluate y at t = 3 and subtract y at t = 2:

Δy = y(3) - y(2) = (44 * 3 - 16 * 3^2) - (44 * 2 - 16 * 2^2)

   = (132 - 144) - (88 - 64)

   = -12 - 24

   = -36 feet

The change in time (Δt) is 3 - 2 = 1 second.

Average velocity = Δy / Δt = -36 feet / 1 second = -36 feet/second

Therefore, the average velocity for the time period from t = 2 to t = 3 is -36 feet/second.

Equilibrium pressure of NO is 3.82 atm

The equilibrium pressure of NO is calculated from the equation of the reaction given below as follows:

N₂ + O₂ ⇄ 2 NO

Initial pressure of N₂ = 21.76 atm

Equilibrium pressure of N₂ = 21. 76 - x atm

Initial pressure of O₂ = 9.32 atm

Equilibrium pressure of O₂ = 9.32 - x atm

Initial pressure of NO = 0 atm

Equilibrium pressure of NO = 2x atm

Equilibrium constant = 0.050

0.050 = 2x²/(9.32 - x)(21. 76 - x)

2x² = 0.05(202.8 - 31.08x + x²)

2x² = 10.14 - 1.554x + 0.05x²

1.95x² + 1.554x - 10.14

x = 1.91 atm

2x = 3.82 atm

When a bus starts from rest and accelerates uniformly with an acceleration of 0.1 m/s^2 for 2 minutes, its final velocity will be 12 m/s.

The bus starts from rest, which means its initial velocity is zero. It then accelerates uniformly with an acceleration of 0.1 m/s^2 for a duration of 2 minutes. To find the final velocity of the bus, we can use the equation:

final velocity = initial velocity + (acceleration × time)

Since the initial velocity is zero, we can simplify the equation to:

final velocity = acceleration × time

Given that the acceleration is 0.1 m/s^2 and the time is 2 minutes, we need to convert the time to seconds. There are 60 seconds in a minute, so 2 minutes is equal to 2 × 60 = 120 seconds. Plugging in the values:

final velocity = 0.1 m/s^2 × 120 s = 12 m/s

Therefore, the bus will have a final velocity of 12 m/s after 2 minutes of uniform acceleration.

In summary, when a bus starts from rest and accelerates uniformly with an acceleration of 0.1 m/s^2 for 2 minutes, its final velocity will be 12 m/s.

Velocity and speed are two concepts that are often used interchangeably, but they actually have different meanings. Speed refers to how fast an object is moving, while velocity refers to both the object's speed and the direction in which it is moving.

For example, a car traveling at 60 miles per hour north has a velocity of 60 miles per hour north, while a car traveling at 60 miles per hour east has a velocity of 60 miles per hour east. In other words, velocity takes into account the object's speed and the direction in which it is moving. On the other hand, speed only refers to how fast the object is moving, regardless of its direction.

The wing loading of the aircraft is approximately 1128.6 N/m².

The required power to maintain a constant cruising speed of 300 km/h is approximately 173791.5 W.

1. Lift = Weight

1/2 * density * velocity² * wing area * lift coefficient = mass * gravity

1/2 * 1.225 * velocity² * 35 * 0.45 = 4000 * 9.81

Simplifying and solving for velocity, we get:

velocity = ✓((4000 * 9.81 * 2) / (1.225 * 35 * 0.45)) = 41.6 m/s

The rate of heat that must be supplied to the engine for it to produce 5 hp of power is 7635 btu/h.

The formula for the efficiency of a completely reversible heat engine:

Efficiency = 1 - (Tc/Th)

where Tc is the temperature of the cold sink and Th is the temperature of the hot source. Since the engine is completely reversible, it operates at the maximum possible efficiency, which means:

Efficiency = 1 - (Temperature_sink / Temperature_source)
Efficiency = 1 - (500/1500) = 2/3

We also know that power (P) is related to the rate of heat transfer (Q) by the formula:

P = Q x efficiency

We can rearrange this formula to solve for Q:

Q = P / efficiency

Plugging in the given values, we get:

Q = (5 hp x 2545 btu/hp) / (2/3) = 7635 btu/h

In relation to line locators, conductive refers to a direct connection between the pipe and transmitter. Conductive locating involves connecting a transmitter to a metallic pipe or cable and then using a receiver to detect the signal transmitted through the pipe or cable.

The transmitter sends an electrical signal through the conductive material, which is then picked up by the receiver. This technique is particularly useful when locating pipes or cables that are buried underground or hidden behind walls. By using conductive locating, line locators can accurately determine the location, depth, and direction of the pipe or cable. In contrast, an indirect connection with radio waves, as in option B, is referred to as inductive locating, which involves detecting the electromagnetic field around the pipe or cable. While inductive locating can be useful in some situations, such as locating non-conductive pipes or cables, it is less accurate than conductive locating.

Explanation:

The focal length of the second lens is -17.7 cm.

The distance between the original object and the final image is 2.56 cm to the left of the first lens.

To find the focal length of the second lens, we can use the thin lens equation:

1/f = 1/do + 1/di

where f is the focal length of the lens, do is the object distance, and di is the image distance.

For the first lens, we have:

1/f1 = 1/do + 1/di1

where f1 = 8.40 cm, do = -28.0 cm (since the object is to the left of the lens), and di1 is the image distance produced by the first lens.

Using the thin lens equation, we can solve for di1:

1/8.40 = 1/-28.0 + 1/di1

di1 = 11.76 cm

The image produced by the first lens is located 11.76 cm to the right of the first lens.

Now, we can use the image produced by the first lens as the object for the second lens:

do2 = di1 = 11.76 cm

We also know that the final image height is 5.60 mm and is inverted relative to the object, so the image distance produced by the second lens, di2, must be negative.

Using the thin lens equation again, we can solve for the focal length of the second lens, f2:

1/f2 = 1/do2 + 1/di2

where do2 = 11.76 cm and di2 = -? (to be determined).

We can solve for di2:

1/f2 = 1/11.76 + 1/di2

di2 = -6.08 cm

Now we can solve for f2:

1/f2 = 1/11.76 - 1/6.08

f2 = -17.7 cm

Therefore, the focal length of the second lens is -17.7 cm (negative because it is a converging lens, as required to produce an inverted image).

The distance between the original object and the final image can be found by adding the object distance for the first lens, the image distance for the first lens, the distance between the two lenses (8.00 cm), the object distance for the second lens, and the image distance for the second lens:

dtotal = do1 + di1 + d12 + do2 + di2

were d12 = 8.00 cm

Substituting the values we found earlier, we get:

dtotal = -28.0 + 11.76 + 8.00 + 11.76 - 6.08

dtotal = -2.56 cm

Therefore, the distance between the original object and the final image is 2.56 cm to the left of the first lens.
