(c) determine the horizontal force required to satisfy equilibrium for the specified area and show the location and direction of this force in the sketch.

Answer:

To determine the compressibility and bulk modulus of elasticity of a gas, we can use the following formulas:

Compressibility:

β = - (1/V) * (∆V/∆P)

where V is the initial volume of the gas, ∆V is the change in volume, and ∆P is the change in pressure.

Bulk modulus of elasticity:

B = - V * (∆P/∆V)

where V is the initial volume of the gas, ∆V is the change in volume, and ∆P is the change in pressure.

Using the given values, we can calculate the compressibility as follows:

∆V = V2 - V1 = 0.111m3 - 0.30m3 = -0.189m3

∆P = P2 - P1 = 202.8kPa - 50.7kPa = 152.1kPa

Therefore,

β = - (1/0.30m3) * (-0.189m3/152.1kPa) ≈ 0.0048 kPa^-1

Similarly, we can calculate the bulk modulus of elasticity as follows:

B = - 0.30m3 * (152.1kPa/-0.189m3) ≈ 2418 kPa

Therefore, the compressibility of the gas is approximately 0.0048 kPa^-1, and the bulk modulus of elasticity is approximately 2418 kPa.

Explanation:

An automobile travels along a straight road at 15.65 m/s through a 11.18 m/s speed zone. A police car observed the automobile. At the instant that the two vehicles are abreast of each other, the police car starts to pursue the automobile at a constant acceleration of 1.96 m/s2 . The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit and applied his brakes and decelerates at 3.05 m/s2

Find the total time required for the police car  to over take the automobile.

Answer:

15.02 sec

Explanation:

The total time required for the police car to overtake the automobile is related to the distance covered by both  cars which is equal from instant point of abreast.

So; we can say :

\(D_{pursuit} =D_{police}\)

By using the second equation of motion to find the distance S;

\(S= ut + \dfrac{1}{2}at^2\)

\(D_{pursuit} = (15.65 *12 )+(15.65 (t)+ (\dfrac{1}{2}*(-3.05)t^2)\)

\(D_{pursuit} = (187.8)+(15.65 \ t)-0.5*(3.05)t^2)\)

\(D_{pursuit} = (187.8+15.65 \ t-1.525 t^2)\)

\(D_{police} = ut _P + \dfrac{1}{2}at_p^2\)

where ;

u  = 0

\(D_{police} = \dfrac{1}{2}at_p^2\)

\(D_{police} = \dfrac{1}{2}*(1.96)*(t+12)^2\)

\(D_{police} = 0.98*(t+12)^2\)

\(D_{police} = 0.98*(t^2 + 144 + 24t)\)

\(D_{police} = 0.98t^2 + 141.12 + 23.52t\)

Recall that:

\(D_{pursuit} =D_{police}\)

\((187.8+15.65 \ t-1.525 t^2)= 0.98t^2 + 141.12 + 23.52t\)

\((187.8 - 141.12) + (15.65 \ t - 23.52t) -( 1.525 t^2 - 0.98t^2) = 0\)

= 46.68 - 7.85 t -2.505 t² = 0

Solving by using quadratic equation;

t = -6.16 OR  t = 3.02

Since we can only take consideration of the value with a  positive integer only; then t = 3.02 secs

From the question; The motorist noticed the police car in his rear view mirror 12 s after the police car started the pursuit;

Therefore ; the total time  required for the police car  to over take the automobile = 12 s + 3.02 s

Total time  required for the police car  to over take the automobile = 15.02 sec

If the maximum gain in the passband is 8 dB, then the gain at the cutoff frequency is 8 dB - 3 dB = 5 dB.

This is because, as mentioned in the question, the cutoff frequency is the point where the gain is 3 dB lower than the maximum gain. Since the maximum gain is 8 dB, the gain at the cutoff frequency would be 8 dB - 3 dB = 5 dB.

You need to configure a DNS A record for the intranet site's hostname to map it to the correct IP address.

What is DNS?
DNS, or Domain Name System, is an internet protocol used to translate domain names, such as www.example.com, into IP addresses, such as 192.168.2.1, that computers can understand and use to communicate with each other. DNS acts as a directory service, providing a link between domain names and their associated IP addresses, which are stored and managed in a distributed database system. DNS is essential for the functioning of the internet, allowing users to access websites and services without having to remember their numerical IP addresses. DNS works by querying a distributed network of DNS servers, which maintain a database of IP addresses and their corresponding domain names. When a DNS query is made, the DNS server looks up the requested IP address in its database and returns it to the user. DNS is an important part of the internet infrastructure and is used by many different types of services, such as email, web hosting, and streaming services.

Answer:

a) the COP of this air conditioner is 2.38

b) the rate of heat transfer to the outside air is 1065 kJ/min

Explanation:

Given the data in the question;

[ Outdoor ] ←  Q\(_H\) [ W\(_{net, in\) ] Q\(_L\) ← [ House ]

Rate of heat removed from the house; Q\(_L\)  = 750 kJ/min = ( 750 kJ/min × ( 1 kW / 60 kJ/min ) ) = 12.5 kW

Net-work input; W\(_{net, in\) = 5.25 kW

a) The coefficient of performance of the air conditioner; COP.

COP = Q\(_L\) / W\(_{net, in\)

we substitute

COP = 12.5 kW / 5.25 kW

COP = 2.38

Therefore, the COP of this air conditioner is 2.38

b) the rate of heat transfer to the outside air.

Q\(_H\) = Q\(_L\) + W\(_{net\)

we substitute

Q\(_H\) = 12.5 kW + 5.25 kW

Q\(_H\) = 17.75 kW

Q\(_H\) = ( 17.75 × 60 ) kJ/min

Q\(_H\) = 1065 kJ/min

Therefore, the rate of heat transfer to the outside air is 1065 kJ/min

Voltage determines the bare minimum distance from an exposed electrical conductor that is safe.

Electrical charge carriers, frequently electrons or ions, move effortlessly from atom to atom in a conductor when voltage is applied. Because they have free electrons, conductors easily conduct electrical current. Insulators are poor conductors because they resist electrical current.

By moving through materials, electrons produce electricity. Copper wires and other materials that permit electron flow are referred to as conductors, whereas rubber and other materials that prevent electron flow are referred to as insulators.

The required ventilation rate is 400 cfm.

H = height office = 10 feet

W = width office = 20 feet

L = length office = 20 feet

ACPH = air change per hour = 6

Basically the formula to calculate the required ventilation rate is by multiply the ACPH with the space volume.

We know the office space have block shape with volume formula is H*W*L. So the required ventilation rate is,

Required ventilation rate = 6 * (10 * 20 * 20)

= 24,000 cubic feet per hour

Since the question want the result in cfm or cubic feet per minute, so we divide the result by 60 to convert that to cfm. So,

CFM = 24,000 / 60

= 400 cfm

Thus, the required ventilation rate in cfm is 400.

The act of spooling a print job helps free up paged memory space on the print server. The correct answer is (a) Paged memory space.

Spooling a print job is a process of sending the print job to a temporary file on the hard drive before it is sent to the printer. This helps free up paged memory space on the print server because the print job is not taking up memory while waiting to be printed. Spooling also allows multiple print jobs to be queued up and processed in the order they were received, which helps to prevent printer congestion and improves printing efficiency.

Option A is the correct answer because spooling a print job helps to free up paged memory space on the print server. Options B and C are not directly related to spooling print jobs, and option D is not entirely accurate because spooling print jobs actually uses hard drive storage temporarily before printing, but it ultimately helps to free up memory resources.

Answer:

Explanation:

It appears that you are trying to solve a problem involving an insulated rigid tank containing saturated liquid water and water vapor. To determine the volume of the tank, you will need to know the mass of the liquid water and the mass of the water vapor. The mass of the liquid water can be calculated by multiplying the mass of the water and vapor mixture by the fraction of the mixture that is liquid water (1.4 kg * 0.25 = 0.35 kg). The mass of the water vapor can be calculated by subtracting the mass of the liquid water from the total mass of the mixture (1.4 kg - 0.35 kg = 1.05 kg).

To determine the final temperature of the tank, you will need to know the amount of heat added to the tank by the electric resistor and the specific heat capacity of the water and water vapor mixture. The specific heat capacity is a measure of the amount of heat required to raise the temperature of a substance by a certain amount. The specific heat capacity of water is 4.186 J/g°C, and the specific heat capacity of water vapor is 2.080 J/g°C.

To determine the electric power rating of the resistor, you will need to know the amount of heat added to the tank by the resistor and the time over which the heat was added. The power rating of the resistor is equal to the amount of heat added to the tank divided by the time over which the heat was added.

I hope this helps clarify the problem and provide some guidance on how to solve it. If you have any further questions or need additional help, please don't hesitate to ask.

Answer:

The velocity at section is approximately 42.2 m/s

Explanation:

For the water flowing through the pipe, we have;

The pressure at section (1), P₁ = 300 kPa

The pressure at section (2), P₂ = 100 kPa

The diameter at section (1), D₁ = 0.1 m

The height of section (1) above section (2), D₂ = 50 m

The velocity at section (1), v₁ = 20 m/s

Let 'v₂' represent the velocity at section (2)

According to Bernoulli's equation, we have;

\(z_1 + \dfrac{P_1}{\rho \cdot g} + \dfrac{v^2_1}{2 \cdot g} = z_2 + \dfrac{P_2}{\rho \cdot g} + \dfrac{v^2_2}{2 \cdot g}\)

Where;

ρ = The density of water = 997 kg/m³

g = The acceleration due to gravity = 9.8 m/s²

z₁ = 50 m

z₂ = The reference = 0 m

By plugging in the values, we have;

\(50 \, m + \dfrac{300 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{(20 \, m/s)^2}{2 \times 9.8 \, m/s^2} = \dfrac{100 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)50 m + 30.704358 m + 20.4081633 m = 10.234786 m + \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

50 m + 30.704358 m + 20.4081633 m - 10.234786 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

90.8777353 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

v₂² = 2 × 9.8 m/s² × 90.8777353 m

v₂² = 1,781.20361 m²/s²

The range of force exerted at the end of the rope is; 285.7 N to 1,000 N.

The net horizontal force of the cylinder when it is at equilibrium position can be found by applying Newton's second law of motion. Thus;

∑F = 0

F - μF_n = 0

We are given;

F_n = 5 kN = 5000 N

μ = 0.2

Thus;

F - 0.2(5,000) = 0

F - 1,000 = 0

F = 1,000 N

The strength of the applied force will be increasing as the number of turns of the rope increases. Thus;

Minimum force = Total force/number of turns of rope

Since rope is wrapped three and half times, then;

number of turns = 3.5

Thus;

minimum force = 1,000/3.5

minimum force = 285.7 N

Thus, the range of force exerted at the end of the rope is 285.7 N to 1,000 N.

A Pb-Sn alloy contains 23% primary alpha phase (α) and 77% eutectic microconstituent immediately after the eutectic reaction.

How to determine the composition?

To determine the composition of the alloy, we will refer to the Pb-Sn phase diagram. The eutectic composition in this system is approximately 61.9% Sn and 38.1% Pb. Since the eutectic microconstituent makes up 77% of the alloy, the primary alpha phase (which is the Pb-rich phase) contributes the remaining 23%. By using a lever rule calculation, you can determine the exact composition of the alloy.

Therefore, the composition of the alloy immediately after the eutectic reaction is 0% alpha and 100% eutectic microconstituent.

Water content (w%) = 12%Degree of saturation (Sr) = 75%Specific gravity of solids (Gs) = 2.65We have to calculate the total unit weight, void ratio (e), and porosity (n).Calculation:

First, we have to calculate the dry unit weight, γd

Dry unit weight, γd = γw / (1 + w%)

Let's calculate γw

Water content (w%) = 12%

So, moisture content (w) = w% * γd / 100= 12/100 * 1.65= 0.198 kg/kg of dry soil

Total weight of soil (Wt) = Weight of solids (Ws) + Weight of water (Ww)

Weight of solids (Ws) = Volume of solids (Vs) * Gs * γw/Vs = 1

Total volume of soil = Volume of solids (Vs) + Volume of voids (Vv)

Let's calculate Vv Degree of saturation (Sr) = 75%Vv/Vs = Sr / (1 - Sr)= 0.75 / 0.25= 3

Total volume of soil = Volume of solids (Vs) + Volume of voids (Vv)= 1 + 3= 4m^3

Let's calculate the weight of water,

WwWw = Wt - WsWw = 4 * 0.12 = 0.48 kg

Weight of solids, Ws = Gs * γs * Vsγs = (Wt - Ww) / Vst = (1 - 0.12) * 1.65= 1.452 kg/ m^3

Ws = Gs * γs * Vs= 2.65 * 1.452= 3.85 kg

Total unit weight, γ= Wt / Vt= (Ws + Ww) / Vt= (3.85 + 0.48) / 4= 1.0825 kg/m^3

Now, calculate the void ratio, eVv/Vs = 3Vv / Vt = Vv / (Vs + Vv) = 3 / 4e = Vv / Vs = 3 / 1 = 3

Porosity, n= Vv / Vt= 3 / 4= 0.75
