Answer:

No.

Explanation:

\(P_r\) = Power rating = 1 W

R = Resistance = \(350\ \Omega\)

V = Voltage = \(24\ \text{V}\)

Power is given by

\(P=\dfrac{V^2}{R}\\\Rightarrow P=\dfrac{24^2}{350}\\\Rightarrow P=1.65\ \text{W}\)

\(1.65\ \text{W}>1\ \text{W}\)

So

\(P>P_r\)

Hence, the resistor is not operating within its power rating.

Explanation:

Answer:

1. i. 20 Nm ii. 4.85 HP

2. 16.5 %

Explanation:

1) Determine the torque and the power developed at 4% slip when a reduced voltage of 340V is applied.

i. Torque

Since slip is constant at 4 %,torque, T ∝ V² where V = voltage

Now, T₂/T₁ = V₂²/V₁² where T₁ = torque at 690 V = P/2πN where P = power = 20 HP = 20 × 746 W = 14920 W, N = rotor speed = N'(1 - s) where s = slip = 4% = 0.04 and N' = synchronous speed = 120f/p where f = frequency = 60 Hz and p = number of poles = 4.

So, N' = 120 × 60/4 = 30 × 60 = 1800 rpm

So, N = N'(1 - s) = 1800 rpm(1 - 0.04) = 1800 rpm(0.96) = 1728 rpm = 1728/60 = 28.8 rps

So, T = P/2πN = 14920 W/(2π × 28.8rps) = 14920 W/180.96 = 82.45 Nm

T₂ = torque at 340 V, V₁ = 690 V and V₂ = 340 V

So, T₂/T₁ = V₂²/V₁²

T₂ = (V₂²/V₁²)T₁

T₂ = (V₂/V₁)²T₁

T₂ = (340 V/690 V)²82.45 Nm

T₂ = (0.4928)²82.45 Nm

T₂ = (0.2428)82.45 Nm

T₂ = 20.02 Nm

T₂ ≅ 20 Nm

ii. Power

P = 2πT₂N'

= 2π × 20 Nm × 28.8 rps

= 1152π W

= 3619.11 W

converting to HP

= 3619.11 W/746 W

= 4.85 HP

2) What must be the new slip for the motor to develop the same torque when the reduced voltage is applied

Since torque T ∝ sV² where s = slip and V = voltage,

T₂/T₁ = s₂V₂²/s₁V₁²

where T₁ = torque at slip, s₁ = 4% and voltage V₁ = 690 V and T₂ = torque at slip, s₂ = unknown and voltage V₂ = 340 V

If the torque is the same, T₁ = T₂ ⇒ T₂T₁ = 1

So,

T₂/T₁ = s₂V₂²/s₁V₁²

1 = s₂V₂²/s₁V₁²

s₂V₂² = s₁V₁²

s₂ = s₁V₁²/V₂²

s₂ = s₁(V₁/V₂)²

substituting the values of the variables into the equation, we have

s₂ = s₁(V₁/V₂)²

s₂ = 4%(690/340)²

s₂ = 4%(2.0294)²

s₂ = 4%(4.119)

s₂ = 16.47 %

s₂ ≅ 16.5 %

We can say that the given function n^3/1000 - 100n^2 - 100n + 3 is in the Θ(n^3) notation, as it is bounded above and below by some multiple of n^3 for sufficiently large n.

To explain why the given function n^3/1000 - 100n^2 - 100n + 3 is in the Θ(n^3) notation, we need to show that it is bounded above and below by some multiple of n^3 for large enough n.

First, let's consider the highest-order term in the function, which is n^3/1000. As n grows larger, the influence of the other terms in the function diminishes relative to n^3/1000. Therefore, for sufficiently large n, the function is dominated by the term n^3/1000. We can drop the lower-order terms and coefficients and write the function as Θ(n^3/1000).

Next, we can simplify Θ(n^3/1000) to Θ(n^3) because Θ notation ignores constant factors. Specifically, any function that is bounded above and below by some multiple of n^3/1000 is also bounded above and below by some multiple of n^3. In other words, we can multiply n^3/1000 by any constant factor and still have a function that is Θ(n^3).

Therefore, we can say that the given function n^3/1000 - 100n^2 - 100n + 3 is in the Θ(n^3) notation, as it is bounded above and below by some multiple of n^3 for sufficiently large n.

Answer:

The maximum deflection of a cantilever beam can be found using the equation for a cantilever beam under a point load and a distributed load:

δ = (PL^3)/(3 * EI) + (wl^2)/8 * (2L - wl)

where δ is the maximum deflection, P is the point load (20 kN), L is the length of the beam (2 m), w is the distributed load (10 kN/m), E is the Young's modulus of the material, I is the moment of inertia, and l is the length of the distributed load (1 m).

First, let's convert the loads to N and the length to mm:

P = 20 kN * 1000 N/kN = 20000 N

L = 2 m * 1000 mm/m = 2000 mm

w = 10 kN/m * 1000 N/kN * 1000 mm/m = 10000 N/mm

l = 1 m * 1000 mm/m = 1000 mm

EI = 2 x 10^9 KNmm^2

Next, let's plug the values into the equation for maximum deflection:

δ = (P * L^3)/(3 * EI) + (w * l^2)/8 * (2L - l)

δ = (20000 N * 2000^3 mm^3)/(3 * 2 x 10^9 KNmm^2) + (10000 N/mm * 1000^2 mm^2)/8 * (2 * 2000 mm - 1000 mm)

δ = (20000 * 8 x 10^9 mm^3)/(3 * 2 x 10^9 KNmm^2) + (10000 * 10^6 mm^2)/8 * (4000 mm - 1000 mm)

δ = 1.6 x 10^3 mm + 6.25 x 10^4 mm

δ = 6.41 x 10^4 mm = 64.1 mm

So the maximum deflection of the cantilever beam is 64.1 mm.

When electric power is transferred over a long distance then, line loss can be reduced by high voltage and low current. Thus, option A is correct.

The complete question is attached to the image below.

The electric circuit transfers the electric current then it is called electric power. The loss in the line over a larger distance is reduced by transferring AC instead of DC voltage.

The AC transmitted is of high voltage, and the power is low. The equation for current is given,

P = VI

The increase in the voltage causes the decrease in the current and in turn the resistance also reduces resulting in the loss of the power of the circuit to decrease.

Therefore, the loss is reduced by transferring high voltage and, low current AC.

For those who run or work in a business that handles food, you understand the importance of food safety and regulation compliance as it pertains to not only to certification and licensing of a company, but also the life or death of those who consume the products. Because food safety is such an important issue, we want to ensure that all companies who work in the production, preparation, or processing of food have the tools and information they need to ensure they are in full compliance 100% of the time. One slip in food safety compliance could cost someone their health or life, and this information spreads mistrust in the general public toward the company who sold the product, and also the entire product across companies throughout an entire country and beyond. So how does each company working with food ensure they comply with each and every food safety regulation? Through excellent auditing tools.

Auditing in Food Safety Must Change

Auditing in food safety compliance is essential in ensuring that all regulations are being complied with. Most auditing practices for major companies are severely out of date. Many rely on several different forms, stacks of paperwork, and data stored on multiple different computers and databases. This is incredibly inefficient, as it can be easy to miss something when comparing one sheet to the next, and paper can easily be lost or destroyed. It is also time consuming for companies to share audits over separate computers and databases, as it must be passed down from one employee to the next. Technology has granted all food safety compliance managers a simple solution. Auditing apps are the new wave solutions for companies who want all of their data stored on one cloud database that is instantly accessible with real-time data for all employees. This means that no one ever gets left out of the loop, and no new information will fall through the cracks.

Answer:

Super critical

1.2 m

Explanation:

Q = Flow rate = \(12\ \text{m}^3/\text{s}\)

w = Width = 3 m

d = Depth = 90 cm = 0.9 m

A = Area = wd

v = Velocity

g = Acceleration due to gravity = \(9.81\ \text{m/s}^2\)

\(Q=Av\\\Rightarrow v=\dfrac{Q}{wd}\\\Rightarrow v=\dfrac{12}{3\times 0.9}\\\Rightarrow v=4.44\ \text{m/s}\)

Froude number is given by

\(Fr=\dfrac{v}{\sqrt{gd}}\\\Rightarrow Fr=\dfrac{4.44}{\sqrt{9.81\times 0.9}}\\\Rightarrow F_r=1.5\)

Since \(F_r>1\) the flow is super critical.

Flow is critical when \(Fr=1\)

Depth is given by

\(d=(\dfrac{Q^2}{gw^2})^{\dfrac{1}{3}}\\\Rightarrow d=(\dfrac{12^2}{9.81\times 3^2})^{\dfrac{1}{3}}\\\Rightarrow d=1.2\ \text{m}\)

The depth of the channel will be 1.2 m for critical flow.
