True or False: in terms of assessment, it is useful to inquire about family perspectives on issues inherent in each of the layers.

The total power derived from the the plate that heats the room, given the temperature in the room would be  2.065 W.

To calculate the total power radiated from the plate, we'll use the Stefan-Boltzmann law:

P = ε x σ x A x (T_plate^4 - T_room^4)

First, let's convert the temperatures to Kelvin:

Tplate = 79°C + 273.15K = 352.15K

Troom = 22°C + 273.15K = 295.15K

Now, we can plug in the values into the Stefan-Boltzmann law:

P = 0.63 x (5.67 x 10^-8 W/(m^2 x K^4)) x 0.307 m^2 x (352.15^4 K^4 - 295.15^4 K^4)

P ≈ 8.638 x 10^-6 x 239103.81

P = 2.065 W

Answer:

Rebound Hammer test is a Non-destructive testing method of concrete which provide a convenient and rapid indication of the compressive strength of the concrete. The rebound hammer is also called as Schmidt hammer that consist of a spring controlled mass that slides on a plunger within a tubular housing.

The operation of rebound hammer is shown in the fig.1. When the plunger of rebound hammer is pressed against the surface of concrete, a spring controlled mass with a constant energy is made to hit concrete surface to rebound back. The extent of rebound, which is a measure of surface hardness, is measured on a graduated scale. This measured value is designated as Rebound Number (rebound index). A concrete with low strength and low stiffness will absorb more energy to yield in a lower rebound value.

Answer:

L = 75.25 mm

Explanation:

First we need to find the lateral strain:

Lateral Strain = Change in Diameter/Original Diameter

Lateral Strain = (20.025 mm - 20 mm)/20 mm

Lateral Strain = 1.25 x 10⁻³

Now, we will find the Poisson's Ratio:

Poisson's Ratio = (E/2G) - 1

where,

E = Elastic Modulus = 105 GPa

G = Shear Modulus = 39.7 GPa

Therefore,

Poisson's Ratio = [(105 GPa)/(2)(39.7 GPa)] - 1

Poisson's Ratio = 0.322

Now, we find longitudinal strain by following formula:

Poisson's Ratio = - Lateral Strain/Longitudinal Strain

Longitudinal Strain = - Lateral Strain/Poisson's Ratio

Longitudinal Strain = - (1.25 x 10⁻³)/0.322

Longitudinal Strain = - 3.87 x 10⁻³

Now, we can fin the original length:

Longitudinal Strain = Change in Length/L

where,

L = Original Length = ?

Therefore,

- 3.87 x 10⁻³ = (74.96 mm - L)/L

(- 3.87 x 10⁻³)(L) + L = 74.96 mm

0.99612 L = 74.96 mm

L = 74.96 mm/0.99612

L = 75.25 mm

A PMOS transistor conducts when the control input (gate) is LOW or at a logic level of 0.

In a PMOS transistor, the source is connected to VDD (the positive supply voltage), and the drain is connected to the output (load). When the gate of the PMOS transistor is at a logic level of 0 or LOW, it creates a channel between the source and drain, allowing current to flow from the source to the drain and turning the transistor ON. This results in a low resistance path between the output and VDD, allowing a high logic level to be present at the output.

Conversely, when the gate of the PMOS transistor is at a logic level of 1 or HIGH, it blocks the channel between the source and drain, preventing current from flowing and turning the transistor OFF. This results in a high resistance path between the output and VDD, causing the output to be pulled up to VDD through a resistor, which translates to a logic level of 0 at the output.

Therefore, a PMOS transistor conducts when the control input (gate) is at a logic level of 0, and it does not conduct when the control input (gate) is at a logic level of 1.

The apparent power is the product of the voltage and the current, so the apparent power is 480 VAC x 15 A = 7,200 VA. The power factor is 0.77 lagging, so the reactive power is 7,200 x 0.77 = 5,544 VAR. The actual power supplied to the motor is the product of the apparent power and the efficiency, which is 7,200 x 0.82 = 5,824 W.

The power produced by the motor is 5,824 W divided by the efficiency, so the power produced by the motor is 5,824/0.82 = 7,121 W or 9.5 HP.
The impedance, resistance, and reactance of each phase of the motor depending on the type of motor and the design of the windings. Generally, the impedance is determined by the resistance and the reactance, so the impedance of each phase can be calculated using Ohm's law. The resistance and reactance are usually determined experimentally using an ohmmeter or an AC clamp meter.

A contractor has a job that should be completed in 100 days. At present, he has 80 men on the job and it is estimated that they will finish the work in 130 days. Of the 80 men, 50 are each paid ₱120.00 a day, 25 at ₱180.00 a day, and 5 at ₱250.00 a day. For each day beyond the original 100 days, a contractor has to pay ₱500.00.

liquidated damages.(a) How many more men should the contractor add so that he would complete the work on time?In the first case, we see that the contractor already has 80 men and they are working for 130 days to complete the job. So, we can use the following formula to determine the additional number of workers required to finish the work in 100 days.

b) If of the additional men, 2 are paid ₱180.00 a day, and the rest at ₱120.00 a day, would the contractor save money by employing more men and not paying the fine Let’s assume that the contractor adds 440 workers, of which 2 are paid ₱180.00 a day and the rest are paid ₱120.00 a day.

The total cost of the new workers is, therefore, ₱9600.00 + ₱4500.00 + ₱49800.00 = ₱63,900.00.The cost of liquidated damages would be calculated as follows:  $$LD = (130-100) \cdot 500 = ₱15,000.00$$.

Therefore, the contractor would save money if he employs more men and not pays the fine. The contractor’s savings would be:$$Savings = LD - Additional cost$$$$= 15000.00 - 63900.00 $$$$= -48900.00$$

Thus, we can see that the contractor would save ₱48,900.00 by employing more men and not paying the fine.

The condition that DC(s) must satisfy for the system to track a ramp reference input with constant steady-state error is DC(0) = 1.

To achieve constant steady-state error when tracking a ramp reference input, the condition that DC(s) must satisfy is that its DC gain (evaluated at s = 0) is nonzero.

In other words, DC(0) should not equal zero.

This condition ensures that the system has a non-zero steady-state response to a ramp input, allowing it to accurately track the desired slope without accumulating an error over time.

A non-zero DC gain implies that there is a non-zero steady-state output even for a constant input, which is necessary to achieve constant steady-state error when the input is a ramp signal.

If nothing is done within the loop to increment num towards the value 5, the loop will go on endlessly notifying the user to "Keep going".

So, an increment of 1 was added to the loop body to increment the variable num. This makes sure the loop terminates.
