Answer:

Resistance of copper = 1.54 * 10^18 Ohms

Explanation:

Given the following data;

Length of copper, L = 3 kilometers to meters = 3 * 1000 = 3000 m

Resistivity, P = 1.7 * 10^8 Ωm

Diameter = 0.65 millimeters to meters = 0.65/1000 = 0.00065 m

\( Radius, r = \frac {diameter}{2} \)

\( Radius = \frac {0.00065}{2} \)

Radius = 0.000325 m

To find the resistance;

Mathematically, resistance is given by the formula;

\( Resistance = P \frac {L}{A} \)

Where;

First of all, we would find the cross-sectional area of copper.

Area of circle = πr²

Substituting into the equation, we have;

Area  = 3.142 * (0.000325)²

Area = 3.142 * 1.05625 × 10^-7

Area = 3.32 × 10^-7 m²

Now, to find the resistance of copper;

\( Resistance = 1.7 * 10^{8} \frac {3000}{3.32 * 10^{-7}} \)

\( Resistance = 1.7 * 10^{8} * 903614.46 \)

Resistance = 1.54 * 10^18 Ohms

Answer:

a) 397.89 ohm

b) attached below

c) 0.707  as a ratio

Gain in dB = 20 log 0.707 = -3 dB

d)  0.8087

Gain in dB = 20 log \(|\frac{Vout}{Vin}|\) = -1.844 dB

Explanation:

A) Find the appropriate resistor

c = 0.01 uf

fc = 40 kHz

cut-off frequency ; fo = \(\frac{1}{2\pi RC }\)

from the above equation  R = \(\frac{1}{2\pi foC}\)  = 397.89 ohm

B) sketch of the circuit  is attached

C) The gain of the filter at the cutoff frequency

fc = 40 kHz,  

C = 0.01 uF ⇒ \(\frac{-j}{2\pi foC }\) =  -j 397.89

Vout = Vin * ( R / R- C )

Vout = Vin * ( 397.89 / (397.89 - j 397.89))

Vout = \(\frac{1}{\sqrt{2} }\)  Vin ∠45⁰

therefore gain = |\(\frac{Vout}{Vin }\)| = \(\frac{1}{\sqrt{2} }\) = 0.707  as a ratio

Gain in dB = 20 log 0.707 = -3 dB

D) Gain of filter at 55 kHz

c = 0.01 uF =  \(\frac{-J}{2\pi foC }\) =  -j 289.373 ohms

Vout = Vin * \(\frac{R}{R-C}\)  

        = Vin * ( 397.89 / ( 397.89 - j 289.373))

Gain in ratio \(|\frac{Vout}{Vin}|\) = 0.8087 ∠ 36.03⁰

therefore gain in ratio = 0.8087

Gain in dB = 20 log \(|\frac{Vout}{Vin}|\) = -1.844 dB

The true statement regarding the above statements is:

"In most turbine engine oil tanks, a slight pressurization of the tank is desired to ensure a positive flow of oil."

In gas turbine engines, the lubrication system plays a crucial role in providing adequate lubrication to the engine components. Wet sump oil systems are commonly used in these engines.

In a wet sump system, the oil is stored in a reservoir or tank located within the engine.

The second statement mentions that in most turbine engine oil tanks, a slight pressurization of the tank is desired. This means that the oil tank is maintained at a slightly higher pressure than the surrounding atmosphere.

This pressurization helps to ensure a positive flow of oil throughout the lubrication system.

When the oil tank is pressurized, it creates a pressure differential that promotes the flow of oil from the tank to the various engine components that require lubrication.

This positive flow is important for ensuring that all the necessary engine parts receive an adequate supply of oil to reduce friction, cool the components, and provide lubrication.

By maintaining a slight pressurization in the oil tank, the risk of oil flow restrictions or air pockets is minimized. It helps to ensure a continuous and uninterrupted supply of oil to critical areas of the engine, contributing to its efficient and reliable operation.

Answer:

\(94.25\)

Explanation:

Given: Handle of jackscrew is 30 cm long. Also, the car raised 2.0 cm with every full turn of the handle.

To find: ideal  mechanical advantage of the jack

Solution:

Let \(d_e\) denotes the distance over which the effort is applied and \(d_r\) denotes the distance that the load travels.

Here,

\(d_r=2\,\,cm\)

\(d_e=2\pi(length\,\,of\,\,the\,\,handle)=2\pi(30)=60\pi\)

So,

Ideal  mechanical advantage of the jack\(\frac{d_e}{d_r}=\frac{60\pi}{2}=30\pi=30(\frac{22}{7})=94.25\)

We can see here that the probability that the number of 0's in the bit string is different from the number of 1's is:  0.055 (3 decimal places).

Let's calculate the probability for each scenario:

In Scenario 1: Number of 0's > Number of 1's

In an 8-bit string, the possible combinations where the number of 0's is greater than the number of 1's are:

00111111, 01011111, 01101111, 01110111, 01111011, 01111101, 01111110

= 7

Scenario 2: Number of 1's > Number of 0's

Similarly, the possible combinations where the number of 1's is greater than the number of 0's are:

11000000, 10100000, 10010000, 10001000, 10000100, 10000010, 10000001

= 7

The total number of possible 8-bit strings is \(2^{8} = 256\).

Thus, the probability that the number of 0's in the bit string is different from the number of 1's is

(7 + 7) / 256 = 14 / 256 ≈ 0.055 (3d.p)

Explanation:

The heat rejected by the engine into the atmosphere is 53440 J.

According to the law of conservation of energy, the total energy of the system (engine + mass) is conserved.

The energy supplied to the system by the engine is used to lift the mass against gravity and to do some work against frictional forces, which ultimately gets dissipated as heat energy into the atmosphere.

The work done in lifting the mass against gravity is given by:

Work = Force x Distance = m x g x h

where

m = mass of the object = 20 kg

g = acceleration due to gravity = 9.8 m/s^2

h = height lifted = 110 m

So, Work = 20 x 9.8 x 110 = 21560 J

The heat energy supplied by the engine is used to do the work and overcome the frictional forces. Therefore, the remaining heat energy must be dissipated into the atmosphere. So, the heat rejected by the engine is:

Heat rejected = Heat supplied - Work done

= 75000 - 21560
