Under the free-space path-loss model, the transmit power required is -91.99 dBm for a distance of 10 m and the transmit power required is -71.99 dBm for a distance of 100 m.

The free-space path-loss model describes how the power of a radio signal decreases as it propagates through space. It is given by:

Pr = Pt × Gt × Gr × (c / 4πdf)²

where:

Pr is the watts of received power (W)

Pt is the transmit power in W

Gt and Gr are the gains of the transmitting and receiving antennas, respectively

c is the speed of light in meters per second (m/s)

f is the carrier frequency in hertz (Hz)

d is the distance between the antennas in meters (m)

Gt = Gr = 1 for an isotropic antenna.

To find the transmit power required to obtain a received power of 1 dBm = 0.001 W for a wireless system with isotropic antennas and a carrier frequency f = 5 GHz:

For d = 10 m:

By entering the specified values into the formula, we obtain:

0.001 W

= Pt × 1 × 1 × (3x10⁸ m/s / 4π × 5x10⁹Hz × 10 m)²

Simplifying and solving for Pt, we get:

Pt = 6.31 x 10⁻¹¹ W

= -91.99 dBm

Therefore, the transmit power required is -91.99 dBm for a distance of 10 m.

For d = 100 m:

By entering the specified values into the formula, we obtain:

0.001 W

= Pt × 1 × 1 × (3x10⁸ m/s / 4π x 5x10⁹ Hz x 100 m)²

Simplifying and solving for Pt, we get:

Pt = 6.31 x 10⁻⁸ W

= -71.99 dBm

Therefore, the transmit power required is -71.99 dBm for a distance of 100 m.

Critical load Fcr or buckling load is the value of load that causes the phenomenon of change from stable to unstable equilibrium state.

With that beign said, first it is neessary to calculate the moment of inercia about the x-axis:

\(Ix= \frac{db^3}{12}\\ Ix = \frac{2.(4)^3}{12} = 10.667in\)

Then it is necessary to calculate the moment of inercia about the y-axis:

\(Iy = \frac{db^3}{12}\\ Iy = \frac{4.(2)^3}{12} = 2.662in\)

Comparing both moments of inercia it is possible to assume that the minimun moment of inercia is the y-axis, so the minimun moment of inercia is 2662in.

And so, it is possible to calculate the critical load:

\(Pc\gamma = \frac{2046\pi ^2E.I}{L^2} \\Pc\gamma= \frac{2046.\pi ^2.(1,6.10^3.10^3).2662}{(10.12)^2} \\Pc\gamma= 5983,9db\)

Answer:

The equilibrium temperature is 109.7°C

The total entropy change for the process is 0.23 kJ/K

Explanation:

The parameters given are;

The initial temperature of aluminium, T₁ₐ = 140°C = 413.15 K

Mass, m₁, of aluminium block = 28 kg

The specific heat of aluminium, c₁, at 400 K = 0.949 kJ/(kg·K)

The initial temperature of iron, T₁ₙ = 60°C = 333.15 K

Mass, m₂, of iron block = 36 kg

The specific heat of iron, c₂, at room temperature = 0.45 kJ/(kg·K)

The heat lost by the aluminium = Heat gained by the iron

The heat lost by the aluminium = m₁ × c₁ × (T₁ₐ - Tₓ)

The heat lost by the aluminium = 28 × 0.949 × (413.15 - Tₓ)

The heat gained by the iron =  m₂ × c₂ × (Tₓ - T₁ₙ)

The heat gained by the iron =  36 × 0.45 × (Tₓ - 333.15)

Hence;

28 × 0.949 × (413.15 - Tₓ) = 36 × 0.45 × (Tₓ - 333.15)

26.572 × (413.15 - Tₓ) = 16.2 × (Tₓ - 333.15)

∴ (26.572 + 16.2) × Tₓ = 26.572 × 413.15 + 16.2 × 333.15

42.772·Tₓ = 16375.2518

Tₓ = 382.85 K = 109.7°C

The total entropy change of the process is given by the following relation;

\(\Delta S = \Delta S_{Fe} + \Delta S_{Al}\)

\(=m_{1}c_{1}ln\dfrac{T_{x}}{T_{1n}}+m_{2}c_{2}ln\dfrac{T_{x}}{T_{1a}}\)

\(=28 \times 0.949 \times ln\dfrac{382.85}{413.15}+36 \times 0.45 \times ln\dfrac{382.85}{333.15} = 0.23 \, \dfrac{kJ}{K}\)

1. using kirchhoff’s rules, construct enough mathematically independent equations to solve for the current of each resistor. then calculate the % error between your measured and theoretical values for the current of each resistor. you must use both of kirchhoff’s rules (you must use at least 1 junction equation) and show work to receive any credi

To solve for the currents in a circuit using Kirchhoff's rules, we need to apply Kirchhoff's junction rule (also known as Kirchhoff's current law) and Kirchhoff's loop rule (also known as Kirchhoff's voltage law).

Let's consider a simple circuit with three resistors connected in series to a voltage source. We'll label the resistors as R1, R2, and R3, and the currents flowing through them as I1, I2, and I3, respectively.

Applying Kirchhoff's junction rule: At any junction or node in the circuit, the sum of the currents entering the node is equal to the sum of the currents leaving the node.

At the junction connecting the three resistors, we have: I1 = I2 + I3 -- Equation (1)

Applying Kirchhoff's loop rule: In any closed loop within the circuit, the sum of the potential differences (voltages) across the elements is equal to zero.

Let's consider the loop that includes R1, R2, and R3. Starting from a reference point, we traverse the loop in a clockwise direction. We can write the equation as follows:

V - I1 * R1 - I2 * R2 - I3 * R3 = 0 -- Equation (2)

These two equations (Equation 1 and Equation 2) are mathematically independent and can be solved simultaneously to determine the values of I1, I2, and I3.

To calculate the percent error between the measured and theoretical values, we need additional information, such as the resistance values (R1, R2, and R3) and the voltage (V) applied across the circuit. With this information, we can substitute the values into the equations and solve them. Then, by comparing the measured values of the currents with the theoretical values obtained from the equations, we can calculate the percent error using the following formula:

% Error = [(Theoretical Value - Measured Value) / Theoretical Value] * 100

Please provide the specific resistance values and the applied voltage to continue with the calculations and provide you with the percent error for each resistor.

Option C is correct. Swage joints must be used to connect two pieces of copper tubing by soldering or brazing without the use of any fittings.

Swaging is the process of fitting the end of one copper tube over the other so that the junction may be brazed or soldered. It is used to unite two copper tubes of the same diameter.

In order to permanently unite fittings to pipes or cables (also known as wire ropes), swaging is most frequently used. After the parts are loosely assembled, the fitting is compressed and deformed by a mechanical or hydraulic tool.

Answer:

A.) Time = 13.75 seconds

B.) Total distance = 339 m

C.) V = 11.18 m/s

D.) V = 10.2 m/s

Explanation: Given that the automobile travels along a straight road at 15.65 m/s through a 11.18 m/s speed zone.

Then,

Initial velocity U of the motorist = 15.65m/s

acceleration a = - 3.05 m/s^2

Initial velocity u of the police man = 11.18 m/s

Acceleration a = 1.96 m/s^2

The police will overtake at distance S as the motorist decelerate and come to rest.

Where V = 0 and a = negative

While the police accelerate.

Using 2nd equation of motion for the motorist and the police

S = ut + 1/2at^2

Since the distance S covered will be the same, so

15.65t - 1/2×3.05t^2 = 11.18t +1/2×1.96t^2

Solve for t by collecting the like terms

15.56t - 1.525t^2 = 11.18t + 0.98t^2

15.56t - 11.18t = 0.98t^2 + 1.525t^2

4.38t = 2.505t^2

t = 4.38/2.505

t = 1.75 seconds approximately

But 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 overtake the automobile will be:

12 + 1.75 = 13.75 seconds

B.) Using the same formula

S = ut + 1/2at^2

Where S = total distance travelled

Substitutes t into the formula

S = 11.18(13.75) + 1/2 × 1.96 (13.75)^2

S = 153.725 + 185.28

S = 339 m approximately

C.) The speed of the police car at the time it overtakes the automobile will be constant = 11.18 m/s

D.) Using first equation of motion

V = U - at

Since the motorist is decelerating

V = 15.65 - 3.05 × 1.75

V = 15.65 - 5.338

V = 10.22 m/s

Therefore, the speed of the automobile at the time it was overtaken by the police car is 10.2 m/ s approximately

A 176.19 kW heater would be required to heat the water in the pool from 70 degrees F to 72 degrees F in 1 hour, assuming the heater is 100% efficient.

To calculate the size of the heater required to heat the water in the pool, we need to use the following formula:

Q = m x c x ΔT

where

Q is the amount of heat required,

m is the mass of the water being heated,

c is the specific heat of water, and

ΔT is the change in temperature.

First, we need to calculate the mass of the water in the pool.

One gallon of water weighs 3.79 kg hence 20 000 gallons will be 75 800 kg

Q = m x c x ΔT

Q = 75,800 kg x 4.184 J/g°C x (72°F - 70°F)

Q = 75,800 kg x 4.184 J/g°C x 2°F

Q = 634,294.4 joules

Now, we need to calculate the power of the heater required to deliver this amount of heat in 1 hour (3600 seconds):

Power = Q / t

Power = 634,294.4 joules / 3600 seconds

Power = 176.19 kW
