What is CPU?

CPU stands for Central Processing Unit and is known as the brain of a computer. It is responsible for executing instructions and carrying out processes that have been given by the user or a program. The CPU is made up of two main components: the Control Unit, which directs the operations of the computer, and the Arithmetic Logic Unit (ALU), which performs calculations and logical operations. The CPU is connected to the motherboard, which in turn is connected to the other components of a computer. The speed of the CPU determines the speed of the computer’s operations, and can be increased by overclocking the CPU.

Answer:

B is correct I believe

The CMRR the device is 5 : 1. The CMRR can be meant as ratio between common model gain and differential model gain.

CMRR refers to the ratio of the common-mode gain with differential-mode gain. The example of CMRR happens when a differential input change of Y volts produces a change of 1 V at the output, and a common-mode change of X volts produces a similar change of 1 V, then the CMRR is X/Y.

Assume  a common-mode input of 1 v, the output of the device is 100 mv is Y

Common mode gain = Vout/Vin

Common mode gain = 0.01/1 = 0.01

Differential mode gain = 1

Then,

CMRR = Common mode gain/ Differential mode gain

CMRR = 0.01/1 = 0.01

Assume when the device has a differential input of 2 mv, the output of the device is 10 v is Y

Common mode gain = Vout/Vin

Common mode gain = 10/2

Common mode gain = 5

Differential mode gain = 10/2-1 = 10

Then,

CMRR = Common mode gain/ Differential mode gain

CMRR = 5/10 = 0.5

Hence, ratio of  the CMRR in device is

CMRR = 0.5/0.1 = 5 : 1

Answer:

Minimum electrical power required = 3.784 Watts

Minimum battery size needed = 3.03 Amp-hr

Explanation:

Temperature of the beverages, \(T_L = 36^0 F = 275.372 K\)

Outside temperature, \(T_H = 100^0F = 310.928 K\)

rate of insulation, \(Q = 100 Btu/h\)

To get the minimum electrical power required, use the relation below:

\(\frac{T_L}{T_H - T_L} = \frac{Q}{W} \\W = \frac{Q(T_H - T_L)}{T_L}\\W = \frac{100(310.928 - 275.372)}{275.372}\\W = 12.91 Btu/h\\1 Btu/h = 0.293071 W\\W = 12.91 * 0.293071\\W_{min} = 3.784 Watt\)

V = 5 V

Power = IV

\(W_{min} = I_{min} V\\3.784 = 5I_{min}\\I_{min} = \frac{3.784}{5} \\I_{min} = 0.7568 A\)

If the cooler is supposed to work for 4 hours, t = 4 hours

\(I_{min} = 0.7568 * 4\\I_{min} = 3.03 Amp-hr\)

Minimum battery size needed = 3.03 Amp-hr

The required diameter (d) for the solid shaft is approximately 48.97 mm.

To determine the required diameter (d) of a solid shaft that can carry the same torque and have the same maximum shear stress as a tube with an outer diameter (D) of 60 mm and a thickness of 15 mm, we need to consider the torque and shear stress equations for solid and hollow circular sections.

For a solid circular shaft, the torque (T) can be calculated using the equation:

T = (π/16) * τ_max * d^3

where τ_max is the maximum shear stress.

For a hollow circular tube, the torque (T) can be calculated using the equation:

T = (π/16) * τ_max * (D^4 - d^4) / D

In this case, we want to find the diameter (d) of the solid shaft that can carry the same torque and have the same maximum shear stress as the given hollow tube with an outer diameter (D) of 60 mm and a thickness of 15 mm.

By equating the torque equations for the solid shaft and the hollow tube, we have:

(π/16) * τ_max * d^3 = (π/16) * τ_max * (D^4 - d^4) / D

We can simplify the equation by canceling out common terms:

d^3 = (D^4 - d^4) / D

Next, we can rearrange the equation:

D * d^3 = D^4 - d^4

Substituting the values for D and rearranging further, we get:

D * d^3 + d^4 = D^4

d^3 = D^4 - (D - 2t)^4

d^3 = (60 mm)^4 - (60 mm - 2 * 15 mm)^4

d^3 = 129,600,000 mm^4 - 20,736,000 mm^4

d^3 = 108,864,000 mm^4

Take the cube root of both sides to solve for d:

d = ∛(108,864,000 mm^4)

d ≈ 48.97 mm

Now, we can solve this equation for the required diameter (d) of the solid shaft. By iterating through different values of d and comparing the left and right sides of the equation, we can find the value of d that satisfies the equation and gives the required diameter for the solid shaft.

Answer:

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.

Explanation:

From Thermodynamics we remember that thermal efficiency of the ideal Otto cycle (\(\eta_{th}\)), dimensionless, is defined by the following formula:

\(\eta_{th} = 1-\frac{1}{r^{\gamma-1}}\) (Eq. 1)

Where:

\(r\) - Compression ratio, dimensionless.

\(\gamma\) - Specific heat ratio, dimensionless.

Please notice that specific heat ratio under cold air standard conditions is \(\gamma = 1.4\).

If we know that \(r = 8.2\) and \(\gamma = 1.4\), then thermal efficiency of the ideal Otto cycle is:

\(\eta_{th} = 1-\frac{1}{8.2^{1.4-1}}\)

\(\eta_{th} = 0.569\)

Under cold air standard conditions, the thermal efficiency of this cycle is 56.9 percent.

This question is incomplete, the missing diagram is uploaded along this answer below;

Answer:

from the diagram, the curve that most closely describes the variation of the local heat transfer coefficient with position along the plate is Option D

Explanation:

Given the data in the question;

We write the expression for the local Nusselt number for Laminar flow over the flat plate;

Nu = \(C\)\((Re_x)^{0.5\) \((Pr)^{1/3\)

Nu = \(C(\frac{Vx}{v})^{0.5}\) \((Pr)^{1/3\)

\(\frac{h_xx}{k}\) = \(C(\frac{V}{v})^{0.5}\)  \((Pr)^{1/3\)  \((x)^{0.5\)

\(h_x\) = \(\frac{1}{x^{1/2}}\)

Next we write down the expression for the local heat flux from the plate with  uniform surface temperature;

q = \(h_xA(\) T\(_s\) - T∞ )

q ∝ \(h_x\)

∴

q ∝  \(\frac{1}{x^{1/2}}\)

The local heat flux decreases with the position as it is inversely proportional to the square root of the position from the leading edge and it will not be zero at the end of the plate.

Therefore, from the diagram, the curve that most closely describes the variation of the local heat transfer coefficient with position along the plate is Option D
