Carnot engine is the most efficient engine. When fireworks explode, energy produced is True. Heat flow from cold to hot is False. Entropy is not the arrow of time is False.

Carnot engine achieves maximum efficiency by operating on a reversible cycle.                                                                                               Therefore, the Carnot engine is considered the most efficient.                   Energy is manifested in the form of light and sound, resulting from the chemical reactions occurring within the firework.                                           Therefore, when fireworks explode, energy is produced is true.                 In reality, heat always flows from hot to cold.                                                 This phenomenon occurs due to the temperature difference between two bodies, and heat naturally transfers from a higher temperature region to a lower temperature region.                                                             Therefore, "Heat flow from cold to hot" is false.                                             Entropy is indeed considered the arrow of time.                                         This is because the entropy of the universe tends to increase with time.   As energy within a system is converted into unusable forms, the randomness or disorder of the system increases, which aligns with the concept of increasing entropy over time.                                                       Therefore, "Entropy is not the arrow of time" is false.

Answer:

The operating principle of a ramp type digital voltmeter is to measure the time that a linear ramp voltage takes to change from level of input voltage to zero voltage (or vice versa).

The initial pressure in the cylinder of 10 bar of argon with \(C_p\) = (5/2)·R

and the added gas at pressure of 50 bar gives the following values.

(a) 400.6 K

(b) 51.184 J

(c) The pressure of the cylinder when it is shipped is 37.194 bar

(a) Adiabatic compression, we have;

\(\dfrac{p_{1}}{p_{2}} = \mathbf{\left (\dfrac{T_{_{1}}}{T_{2}} \right )^{\dfrac{k}{k-1}}}\)

Where;

\(k = \dfrac{C_p}{C_v} = \mathbf{\dfrac{C_p}{C_p - R}}\)

Therefore;

\(K= \mathbf{\dfrac{\frac{5}{2} \cdot R}{\frac{5}{2} \cdot R - R} }= \dfrac{5}{3}\)

Which gives;

\(\dfrac{10}{50} = \left (\dfrac{298}{T_{2}} \right )^{\dfrac{\frac{5}{3} }{\frac{5}{3} -1}} = \left (\dfrac{298}{T_{2}} \right )^{2.5}\)

\(\dfrac{50}{10} = \mathbf{ \left (\dfrac{T_2}{298.15} \right )^{2.5}}\)

\(ln(5)= 2.5\cdot ln\left (\dfrac{T_2}{298.15} \right )\)

\(T_2 = 298 \times e^{\dfrac{ln(5)}{2.5} } \approx \mathbf{567.29\, K}\)

The temperature

Using an ideal gas model, we have;

\(\dfrac{V_{1}}{V_{2}} = \mathbf{\dfrac{P_{2}\times T_{1}}{T_{2} \times P_1}}\)

Which gives;

\(\dfrac{V_{1}}{V_{2}} = \dfrac{50\times 298}{567.29 \times 10} \approx 2.625\)

V₁ = 2.625·V₂

Volume occupied by the gas in the cylinder after the pressure increases is therefore;

\(V_2 = \dfrac{V_1}{2.625} \approx 0.381 \cdot V_1\)

Volume of gas added is therefore;

\(V =V_1 - \dfrac{V_1}{2.625} = 0.619\cdot V_1\)

Considering a molar volume of gas, we have;

0.040 × 0.619 × 2.5×8.3145×(T₃ - 298) = 0.040 × 0.381 × 2.5×8.3145×(567.29 - T₃)

Solving gives;

T₃ ≈ 400.6 K

For a molar volume of gas cylinder, the temperature just after the valve is closed is T₃ ≈ 400.6 K

(b) If the cylinder sits in the storage for a long time, and heat is conducted out, we have;

The temperature of the cylinder will revert to room temperature of 298 K

The heat transferred is therefore;

0.040 × (2.5 × 8.3145 - 8.3145) ×(400.6 - 298) ≈ 51.184

The heat transferred from the cylinder is 51.184 J

(c) The pressure of the gas in the cylinder is therefore;

\(\dfrac{P_1}{T_1} = \mathbf{\dfrac{P_2}{T_2}}\)

Which gives;

\(P_2= \mathbf{\dfrac{P_1}{T_1} \times T_2}\)

Therefore;

\(P_2= \dfrac{50}{400.6} \times 298 \approx 37.194\)

The pressure of the cylinder when it is shipped is 37.194 bar

To find the average power of a series LRC AC circuit with a peak voltage of 123 V, a peak current of 3 A, and a current that lags the voltage by 59°, the average power of the circuit is:
Option A. 614 W

Solution:
To calculate the average power in an AC circuit, we need to use the formula:
P = Vp * Ip * cos(theta)
where P is the average power, Vp is the peak voltage, Ip is the peak current, and theta is the phase angle between the voltage and current.
In this problem, we are given:
Vp = 123 V
Ip = 3 A
theta = 59 degrees
We can convert the phase angle to radians by multiplying by pi/180:
theta = 59 * pi/180 = 1.03 radians
Now we can substitute these values into the formula:
P = 123 V * 3 A * cos(1.03 radians)
Using a calculator, we get:
P = 614 W
Therefore, the answer is (a) 614 W.

Hence the magnitude of the pure moment m will be \(2\times 10^5.\)

Explanation:

Now,

We know that,

\(\frac{M}{I} = \frac{E}{R}\)

Thus, \(M =\frac{EI}{R}\)

Here

R = 10000 mm  

\(I=\frac{1}{12}\times 120\times 10^{3}\\= 10^{4} mm^{4}\)

\(E=2\times 10^{5}n/mm^{2}\\\\E=2\times 10^{5}n/mm^{2}\\\\M={(2\times 10^{5}\times 10^{4})/{10000}}\\\\M=2\times 10^{5}\)

D. The damage it causes is irreversible

Explanation:

Silicosis is a long term lung disease caused by crystalline silica dust inhalation. There is no cure, and once the damage is done it cannot be reversed.

------------------

Like stated above, the damage is irreversible. Option A is incorrect.

Construction workers are constantly moving to build whatever they're working on. The disease will make it hard to breathe and will have a heavy effect on their lungs, preventing them from properly doing their jobs. Additionally, it's possible to get the disease from this job since you're constantly inhaling dust particles.

Silicosis does major damage to the lungs. The dust particles are attacked by the immune system which causes inflammation and eventually leads to areas of hardened and scarred lung tissue.

Thus, the best option is D.

Answer:

the force conveyed by the fibers is 947.93 lb-f

Explanation:

Given the data in the question;

V_f = 80% = 0.8

V_m = 1 - V_f = 1 - 0.8 = 0.2

Now,

length of fibre L_f = length of Nylon L_n

V_f = A_f × L_f = 0.8

V_m = A_n × L_n = 0.2

so

V_f/V_m = A_f/A_n = 0.8/0.2

A_f/A_n = 4

now, the strains in fibre is equal to strains in nylon

(P/AE)f = (P/AE)n

P_f/A_fE_f = P_n/A_nE_n

P_f = (A_f/A_n)(E_f/E_n)(P_n)    

P_f = ( 4 )( 131 / 2.8 )(Pn)  

P_f = 187.14Pn

and P_n = Pf / 187.14

Hence

given that P_total = 953 lb-f

P_f + P_n = 953

P_f + ( P_f / 187.14 ) = 953

P_f( 1 + ( 1 / 187.14 ) ) = 953

P_f( 1.00534359 = 953

P_f = 953 / 1.00534359

P_f = 947.93 lb-f

Therefore, the force conveyed by the fibers is 947.93 lb-f

Explanation:

a) To draw the FBD of the system with the distributed load, we can represent the beam as a simple object with length L and represent the distributed load as a force acting along the length of the beam. The force acting on the beam due to the distributed load is G(x).

b) The equivalent resultant force due to the distributed load G(x) can be found by integrating the load along the length of the beam:

G_equiv = ∫ G(x) dx = ∫ -3x^2 j^ dx

= -x^3 j^ |x=L

= -L^3 j^

The magnitude of the equivalent force is |G_equiv| = L^3, and the line of action is j^ (downwards).

c) To draw the FBD of the beam using the equivalent resultant force, we can represent the beam as a simple object with length L and represent the equivalent force as a single force acting at the end of the beam.

d) The force applied to the end of the rope is F=17.5kN. The vertical reaction force at the support, Ry, can be found using the equation of static equilibrium:

ΣFy = Ry - G_equiv - F = 0

Ry = G_equiv + F = -L^3 j^ + 17.5 kN j^

The mass of the beam per-unit-meter, mx, can be found using the equation of motion:

ΣFy = mx * g

mx = (Ry - F) / g = (-L^3 + 17.5) / -9.81 = (17.5 + L^3) / 9.81 kg/m

Note that the units of L and g must be consistent.
