The output by the equation and energy required for friction is 160,000 J. Efficiency is 0.267 or 26.7% and this efficiency can be improved by friction reduction.

The useful work done by the pump can be calculated as the product of the weight of the water pumped and the height it is lifted. The weight of the water in the tank can be calculated as the density of water times the volume of water in the tank. The volume of water in the tank is half the total volume of the tank, which can be calculated as the cross-sectional area of the tank times its height (8 m). So the weight of the water is:

Volume = cross-sectional area x height = 2 m x 8 m = 16 m³

Weight = Volume x density = 16 m³ x 1000 kg/m³ = 16,000 kg

Useful work = Weight x height = 16,000 kg x 10 m = 160,000 J

The energy required for friction can be estimated as a percentage of the useful work. This percentage depends on the design of the pump, the viscosity of the water and other factors. Assuming a friction loss of 10%, the energy required for friction can be calculated as:

Energy required for friction = 0.1 x 160,000 J = 16,000 J

The efficiency of the pump can be calculated as the ratio of the useful work done by the pump to the energy input. The energy input can be calculated as the product of the power of the motor (1 kW) and the time it is run (10 minutes, or 600 seconds). So the efficiency can be calculated as: Energy input = Power * time = 1 kW x 600 sec = 600,000 J

Efficiency = Useful work / Energy input = 160,000 J / 600,000 J = 0.267 or 26.7%

The efficiency of the pump can be increased by reducing the friction loss, improving the design of the pump to reduce energy losses, or increasing the power of the motor. Another option is to increase the height the water is lifted, as the useful work done by the pump is directly proportional to the height the water is lifted.

To determine the maximum shearing stress and its corresponding plane, you would need to know the value of the axial load p, and the cross-sectional area A of the member.

What is shearing stress?

Shearing stress is a type of stress that occurs in a material when the applied forces generate sliding or slippage along the parallel planes within the material. It is a measure of the force per unit area that is resisting this sliding or shearing.

The maximum shearing stress in a member subjected to axial loading is given by the formula:

τ_max = p / (2A)

where p is the axial load, and A is the cross-sectional area of the member. The plane where the maximum shearing stress occurs is perpendicular to the plane of the cross section.

It is important to note that the maximum shearing stress occurs at 45 degrees to the axis of the member, at the point where the stress is acting at right angles to both the longitudinal and radial axes of the cross section.

Therefore, to determine the maximum shearing stress and its corresponding plane, you would need to know the value of the axial load p, and the cross-sectional area A of the member.

The temperature of the hot bath is approximately 400 °C.  (Option B).

To find the temperature of the hot bath, we need to use the temperature coefficient of resistance (α) of platinum and the resistance at 0°C and 100°C as a reference.

The equation to find the temperature is given by:

T = (R/R0 - 1) / α + T0

Where R is the resistance at the hot bath temperature, R0 is the resistance at 0°C, T0 is 0°C, and α is the temperature coefficient of resistance of platinum.

Using this equation and the given values, we can calculate T as:

T = (5.795/5 - 1) / (5.39/5 - 1) * (100 - 0) + 0 = approximately 400 °C

The boat's velocity relative to the water is 6.8 m/s, in the negative y direction.

To calculate the boat's velocity relative to the water, we first need to subtract the speed of the river from the desired speed of the boat. The desired speed of the boat is 5.0 m/s, and the speed of the river is 1.8 m/s. Thus, the boat's velocity relative to the water is 5.0 m/s - 1.8 m/s = 3.2 m/s.

To determine the direction of the boat's velocity relative to the water, we need to consider the direction of the river and the desired direction of the boat.

The river is flowing in the positive x direction, while the desired direction of the boat is in the negative x direction. Therefore, the direction of the boat's velocity relative to the water is in the negative y direction.

To calculate the magnitude of the boat's velocity relative to the water, we use the Pythagorean theorem. The magnitude of the boat's velocity relative to the water is equal to the square root of the sum of the squares of its x and y components. Thus, the magnitude of the boat's velocity relative to the water is 6.8 m/s (3.2 m/s in the negative y direction).

The heat supplied during compression is 432.26 K and the work done on the air is -3.859 KJ/kg

To find the compression temperature use the formula:

                                      P₁T₁= P₂T₂

To answer this question, we can use the following formula of work:

                                 W = mR (T₁ - T₂)/η - 1

now given,

mass: m = 1 kg

Law PV^1.3 : η = 1.3 (P¹°³)

initial pressure: P₁ = 1.02 bar,

initial temperature: T₁ = 20 + 273 = 293 K

final pressure: P₂ = 5.5 bar

final temperature: T₂ = ?

work: W = ?

Putting the given values ​​in the above equation, we get,

Temperature:

P₁T₁ = P₂T₂

T₂ = P₁T₁/P₂

T₂ = (5.5/1.02)0.3/1.3 × 293

T₂= (5.392)0.2308 × 293

T₂ = 1.4753 x 293

T₂ = 432.26 K.

So, the heat supplied during compression is 432.26 K.

Work:

W = mR (T₁ - T₂)/η - 1   → R = 8.314 J/Kmol

W = 1(8.314)(293 - 432.26)/1.3 - 1

W = 8.314(-139.26)/0.3

W = -1157.8/0.3

A magnifying glass is a simple optical device that uses a convex lens to produce a magnified image of an object.

When a magnifying glass is held close to an object, the lens refracts the light that is reflected off the object and causes it to converge or come together at a point. This point is called the focal point, and it is where the magnified image is formed. The image appears larger and closer than the actual object because it is formed by the light that has been bent and converged by the lens.

The magnification produced by a magnifying glass depends on the power of the lens, which is determined by its focal length.

The frequency of a microwave oven that emits radiation at a wavelength of 500 cm would be  6.00 × 10¹⁰ Hz (B)

The frequency of a radiation in physics is the quantity of waves passing a fixed location in a unit of time. It also indicates how many cycles or vibrations a body in periodic motion experiences in a given unit of time. Heinrich Rudolf's name was given to the SI unit that measures frequency known as the hertz. Additionally, 1 Hz means one cycle per second.

The distance between the two closest points that are in phase with one another is known as a wavelength. As a result, a single full wavelength separates two nearby peaks or troughs on a wave. Typically, the wavelength of a wave is denoted by the letter lambda (λ).

The following formula gives the relationship between wavelength and frequency:

                                                  V = f × λ

Where:

V = wave speed

   = 3 × 10⁸ m/s (speed of light)

F = frequency

λ = wavelength

  = 0.005 m

Thus, the frequency of the microwave would be:

3 × 10⁸ m/s = f × 0.005 m

f = ( 3 × 10⁸ m/s) ÷ (0.005 m)

It will take the boat 47.35 seconds to get to the dock on the northern shore.

The velocity of an object in relation to another object or observer is defined as relative velocity. The time rate of change of one object's relative position with respect to another object is defined as relative velocity.

We can start by using vector addition to find the velocity of the boat relative to the shore.

The velocity of the boat relative to the water is 6.50 m/s, and the velocity of the water relative to the shore is 4.00 m/s,

Let the boat's relative velocity to shore is v(bs)

water relative velocity  to shore is v(ws)

boat's relative velocity to water is v(bw)

So: v(bs) = √(v(bw)² + v(ws)² - 2 × v(bw) × v(ws) × cos(57.0°))

Plugging in the known values, we get:

v(bs) = √(6.50² + 4.00² - 2 × 6.50 × 4.00 × cos(57.0°)) = 5.47 m/s

Next, we can use this velocity to find the time it takes for the boat to cross the river:

t = d / v(bs) = 259.0 m / 7.76 m/s = 47.35 s

Thus, it will take the boat 47.35 seconds.
