Cp=88.15J/mol.K is the molar heat capacity of the substance T is the temperature of the substance in kelvin ΔH=62.626kJ is the enthalpy change of the substance ΔSTe=141.32J/mol.

K is the change in entropy of the substance. The formula for calculating the equilibrium temperature for equation (1) can be given as:ΔH=ΔSTe*TFor the given values of ΔH and ΔSTe, we can calculate the value of temperature T as

:T=ΔH/ΔSTeT=62.626kJ/141.32J/mol.K = 442.87K = 169.72°C.

The calculated temperature is in degrees Celsius. We need to convert this to Kelvin by adding 273.15 to it.

Therefore,T=169.72+273.15 = 442.87K = 140°C

The molar heat capacity Cp is the amount of heat required to raise the temperature of one mole of a substance by one kelvin. The value of Cp depends on the nature of the substance and can be measured experimentally. In this case, Cp=88.15J/mol.K for the substance is given.The temperature of the substance is denoted by T and is given in kelvin.

The enthalpy change of the substance is denoted by ΔH and is given as 62.626kJ. Enthalpy is a measure of the heat released or absorbed during a chemical reaction. The change in entropy of the substance is denoted by ΔSTe and is given as 141.32J/mol.K. Entropy is a measure of the disorder of a system.

The formula for calculating the equilibrium temperature for equation (1) can be given as:ΔH=ΔSTe*T.

This formula relates the enthalpy change of the substance to the change in entropy of the substance and the temperature at which the reaction occurs.

The equilibrium temperature is the temperature at which the forward and reverse reactions occur at the same rate. This is the temperature at which the system is in equilibrium.

If the temperature is below the equilibrium temperature, the forward reaction is favored and if the temperature is above the equilibrium temperature, the reverse reaction is favored.

The calculated temperature is in degrees Celsius. We need to convert this to Kelvin by adding 273.15 to it. Therefore,T=169.72+273.15 = 442.87K = 140°C

Therefore, the equilibrium temperature for equation (1) is 140°C or 442.87K. This temperature is the temperature at which the forward and reverse reactions occur at the same rate.

The first gear set (12-72) provides a speed increase of 6, and the second gear set (8-64) further increases the speed by a factor of 8, resulting in an overall speed increase of 48.

To design a compounded reverted gear train as a step-up gear with a speed increase of 48 times while minimizing the gearbox size and avoiding interference problems, we need to carefully select the numbers of teeth for the gears.

The compounded reverted gear train consists of two sets of gears: the first set is the compound gear train, and the second set is the reverted gear train. The compound gear train is used to achieve a moderate speed increase, and the reverted gear train further amplifies the speed.

To determine suitable numbers of teeth, we can start by considering the speed increase ratio of 48. This ratio can be achieved by breaking it down into smaller ratios for the compound and reverted gear sets. For example, we can choose a speed increase ratio of 6 in the compound gear train and a ratio of 8 in the reverted gear train.

Next, we need to select suitable numbers of teeth for each gear to avoid interference problems and ensure smooth operation. To minimize gearbox size, we aim to keep the gears as small as possible. One approach is to use gears with a small number of teeth, which can help reduce their size.

For the compound gear train, we can select gears with, for example, 12 and 72 teeth. This gives a speed increase ratio of 6. For the reverted gear train, we can choose gears with 8 and 64 teeth, resulting in a speed increase ratio of 8.

The sketch of the designed compounded reverted gear system would show the gear positions and their numbers of teeth as follows:

     ----    12 teeth    ----

   /                              \

--- 72 teeth 8 teeth ---

\ /

      ---- 64 teeth ----

In this configuration, the first gear set (12-72) provides a speed increase of 6, and the second gear set (8-64) further increases the speed by a factor of 8, resulting in an overall speed increase of 48. By carefully selecting the numbers of teeth and the gear ratios, we can achieve the desired speed increase while minimizing the size of the gearbox and avoiding interference problems between the gear teeth.

Harry's fall from the helicopter's height, measured in horizontal distance, from the swimming pool Distance, d = 30 m.

Mark, who is moving at a speed of v = 15 m/s, unintentionally exits a helicopter.

T = 2 seconds later, he dives into a pool.

To determine how far Mark was from the pool when he fell from the helicopter, we must measure the horizontal distance.

Speed is defined as the amount of distance covered in a given amount of time, i.e., s=d/t, where d is the distance covered and t is the passing time.

d=s*t

d=12m/s*2s

d = 30 m

This means that when Mark fell from the helicopter, there was a 30 m gap between him and the swimming pool.

2-Iy=9m r²

3-Iz=10m r².

What is moment of inertia ?

The moment of inertia is a scalar quantity is obtained by the expression.

Sol-

I =∫ r² dm

Where I is the moment of inertia , m the mass of the body and r the distance from the axis of rotation.

In the case of point particles, the expression reduces to

    I = m r²

In this case we calculate with respect to each coordinate axis.

a) With respect to the x axis the distance is x = r, the moment of inertia is

      Iₓ = m r²

with respect to the y-axis, indicate that the distance is y = 3 r.

We calculate

        I_y = m (3r) ²

        I_y = 9 m r²

c) Regarding the z-axis.

We look for the distance.

         z =√x^2+y^2

         z = √ 1^2+3^2

We calculate the moment of interia  Iz = m (10r²)

        Iz = 10 m r²

In conclusion using the definition of moment of inertia we can look for the results of the moment of inertia for each axis are:

  a) Iₓ = m r²

A shape-preserving transformation (movement) in the plane or in space is called an isometric transformation (or isometry). The isometric transformations include translation, rotation, and combinations thereof, such as the glide, which combines a translation with a reflection.

A stiff transformation called an isometry keeps perimeter and area constant while preserving length and angle measurements.

The acceleration of the eraser is 169.19 m/s².

A body travelling in a circle has centripetal acceleration. Due to the fact that velocity is a vector quantity (i.e., it has both a magnitude and a direction), when a body travels in a circle, its direction is continually changing, which causes a change in velocity, which results in an acceleration.

Given that angular velocity of the eraser: ω = 127 rpm

Therefore, the final image of the stamp is located 15.8 cm to the right of the converging lens.

To solve this problem, we can use the thin lens equation and the magnification equation for each lens, and then apply the rules for combining lenses.

(a) The converging lens forms an intermediate image of the stamp:

1/f_con = 1/do + 1/di1

1/12.2 = 1/35.1 + 1/di1

di1 = 22.9 cm (positive, since it is on the same side as the object)

This intermediate image then becomes the object for the diverging lens:

1/f_div = 1/di1 + 1/di2

1/-5.64 = 1/22.9 + 1/di2

di2 = -15.8 cm (negative, since it is on the opposite side from the diverging lens)

Therefore, the final image of the stamp is located 15.8 cm to the right of the diverging lens.

(b) The overall magnification is the product of the magnifications of each lens:

m = m_con * m_div

= (-di1/do) * (-di2/di1)

= (22.9/35.1) * (15.8/22.9)

≈ 0.686

(c) The final image is virtual, since it is formed by a diverging lens.

The system described by the transfer function G(s) = -co² s² + 2a + w², with a damping ratio of 1.3 and a natural frequency of 0.5, has an overdamped unit step response. So, the correct option is (E)

The transfer function of the system is given as G(s) = -co² s² + 2a + w², where co represents the damping ratio, a represents an arbitrary constant, and w represents the natural frequency of the system. We are given that the natural frequency is 0.5 and the damping ratio is 1.3.

To determine the type of unit step response, we need to analyze the damping ratio (co) in relation to the critical damping value (co_critical).

The critical damping ratio (co_critical) is defined as the value where the system is on the threshold between being overdamped and underdamped. It is given by the formula co_critical = 2 * sqrt(a * w²).

In our case, the natural frequency (w) is 0.5, so we can calculate co_critical as follows: co_critical = 2 * sqrt(a * 0.5²).

Since the damping ratio (co) is given as 1.3, we can compare it with co_critical to determine the type of unit step response.

If co > co_critical, the system is considered overdamped (Option E).

If co = co_critical, the system is considered critically damped (Option D).

If co < co_critical, the system is considered underdamped (Option C).

Based on the given values, we can determine that the system is overdamped (Option E) because the damping ratio (1.3) is greater than the critical damping ratio.
