In any chemical reaction, energy must be conserved.

In any chemical reaction, energy must be conserved to uphold the fundamental law of energy conservation. Energy can neither be created nor destroyed; it only transforms from one form to another

. This principle holds true for all chemical reactions, where the total energy of the system remains constant. Energy changes occur as bonds break and form, and if a reaction absorbs more energy than it releases, it is endothermic.

Conversely, exothermic reactions release more energy than they absorb. Energy conservation is crucial not only in understanding the behavior of chemical reactions but also in various other scientific disciplines.

The net force between Superman and Spiderman is 3 N, and it acts in the direction of Superman's force.

As per the question, the force exerted by :

Superman against Spiderman = 28 N

Spiderman against Superman = 25 N,

We can determine the net force and its direction by considering the following:

To find the net force, we need to subtract the forces exerted in opposite directions. Since Superman and Spiderman are pulling against each other, we have:

Net force = Force exerted by Superman - Force exerted by Spiderman

Net force = 28 N - 25 N

Net force = 3 N

The net force between Superman and Spiderman is 3 N.

To determine the direction of the net force, we need to consider the signs of the forces. Since Superman's force is greater than Spiderman's force, the net force will be in the direction of Superman's force.

Thus, the net force of 3 N is in the direction of Superman's force.

Therefore, the net force between Superman and Spiderman is 3 N, and it acts in the direction of Superman's force.

The total energy available increases proportionally to n, the width of the maxima changes inversely proportionally to n². So, as n increases, the width of the maxima will decrease.

Based on the question, we want to determine how the width of the maxima changes when the total energy available increases proportionally to the number of slits, n.

Using the given information, we know that:
1. The maxima fall at the same locations for any number of slits.
2. The peak intensity of the maxima is proportional to n².
3. The total energy at the screen is roughly equal to the product of the number of maxima, peak intensity of a maximum, and the width of a maximum.

Since the total energy available increases proportionally to n, we can write this relationship as:
Total Energy ∝ n

However, we also know that the total energy at the screen is the product of the number of maxima, peak intensity, and the width of a maximum:
Total Energy ∝ (number of maxima) × (peak intensity) × (width of maxima)

As the number and location of the maxima do not change, the peak intensity of the maxima increases proportionally to n²:
Total Energy ∝ n × n² × (width of maxima)

Now we can equate these two expressions:
n ∝ n³ × (width of maxima)

To solve for the width of the maxima, we can divide both sides by n³:
1/n² ∝ width of maxima

For RC circuit: the value of the time constant τ is 12 μs.

For RL circuit: the value of the time constant τ is 0.115 ms.

It is proved that, τ = t1/2/ln(2) = 1.443 t1/2. This shows that the time constant is directly proportional to the square root of the half-life of the voltage decay.

For the RC circuit, the time constant τ is given by:

τ = RC = (10 nF)(1,200 Ω) = 12 μs

For the RL circuit, the time constant τ is given by:

τ = L/RL = (15 mH)/(130 Ω) = 0.115 ms

Now, for the RC circuit, the voltage across the capacitor can be given by:

vC(t) = Vmax(1 - e^(-t/τ))

where Vmax is the maximum voltage of the square wave, τ is the time constant, and t is the time. The voltage across the resistor is equal to vR(t) = vC(t), since the capacitor and resistor are in series.

For the RL circuit, the voltage across the resistor can be given by:

vR(t) = Vmax(1 - e^(-t/τ))

where Vmax is the maximum voltage of the square wave, τ is the time constant, and t is the time.

To show that τ = t1/2/ln(2), we start with the equation for voltage across the capacitor in the RC circuit:

vC(t) = Vmax(1 - e^(-t/τ))

Let t = τ, then we have:

vC(τ) = Vmax(1 - e^(-1))

vC(τ) = 0.632 Vmax

Now, let t = t1/2, then we have:

vC(t1/2) = Vmax(1 - e^(-t1/2/τ))

vC(t1/2) = Vmax(1 - e^(-1/2))

vC(t1/2) = 0.393 Vmax

The voltage across the resistor at t = τ and t = t1/2 can be found using the same equations as above.

Now, the half-life t1/2 is defined as the time it takes for the voltage to decay to half of its initial value. Thus, we have:

t1/2/τ = ln(2)

Solving for τ, we get:

τ = t1/2/ln(2) = 1.443 t1/2

This shows that the time constant is directly proportional to the square root of the half-life of the voltage decay.

The ratio of kinetic energies of a gas at 200 °C and 100 °C is approximately 1.268 .

It can be determined using the equation:

K.E. = (3/2) * n * R * T

Where:

K.E. = Kinetic energy of the gas

n = Number of moles of the gas

R = Gas constant (8.314 J/(mol·K))

T = Temperature in Kelvin

To calculate the ratio of kinetic energies between 200 °C and 100 °C, we need to convert the temperatures to Kelvin.

200 °C = 200 + 273.15 = 473.15 K

100 °C = 100 + 273.15 = 373.15 K

Now, let's calculate the kinetic energy at each temperature:

K.E.(200 °C) = (3/2) * n * R * 473.15

K.E.(100 °C) = (3/2) * n * R * 373.15

To find the ratio, we divide the kinetic energy at 200 °C by the kinetic energy at 100 °C:

Ratio = K.E.(200 °C) / K.E.(100 °C)

     = [(3/2) * n * R * 473.15] / [(3/2) * n * R * 373.15]

Explanation:

This is a simple energy convertion problem. Since there is no friction, and assuming no air drag and other external factors, mechanical energy should be conserved in this system.

Thus, we get:

\(KE_{initial} + PE_{initial} = KE_{final} + PE_{final}\)

We also know that the gravitational potential energy is equal to mgh, while the KE can be calculated using \(\frac{1}{2}mv^2\)

One thing to note here, is that the final KE will be 0, as there is no velocity at the end. Furthermore, we also can set the initial PE as 0 as we are looking at relative height, and at the start it is at h=0.

\(KE_{initial} = PE_{final}\)

The deflection of the beam at point C using the method of superposition is yet to be determined.

To determine the deflection at point C, we can use the method of superposition. This method allows us to analyze the beam's response to multiple independent loads by considering each load separately and then summing up their effects.

First, we consider the deflection caused by Load 1. We apply Load 1 to the beam and calculate the deflection at point C, assuming all other loads are absent. Let's denote this deflection as δ₁.

Next, we consider the deflection caused by Load 2. We apply Load 2 to the beam and calculate the deflection at point C, assuming all other loads are absent. Let's denote this deflection as δ₂.

Finally, we superpose the deflections caused by Load 1 and Load 2 to find the total deflection at point C. The deflection at point C is given by δ = δ₁ + δ₂.

To calculate the deflections δ₁ and δ₂, we need additional information about the specific loads and boundary conditions applied to the beam. Once we have this information, we can proceed with the calculations using the given value of (EI)beam.
