If a 5 tons beam is raised 6 meters, then its potential energy is 294kJ and if it is raised another 8 meters in 6 seconds, the work done is 392kJ

Given the weight of beam(m) = 5tons

The height the beam raised (h) = 6m

We know that potential energy is equal to the weigh raised to a certain height such that PE = mgh where g is the gravitational acceleration.

We know that an object can store energy depending on its position. When a bow and arrow are employed, the kinetic energy of the arrow is provided by the energy accumulated when the bow is drawn.

PE = 5 x 1000 x 9.8 x 6 = 294000J = 294kJ (1 ton = 1000kg)

Hence the potential energy required is 294kJ

In the other case the height the beam raised = 8m

Time taken to raise = 6s.

But potential energy is irrelevant to time. So,

PE = 5000 x 9.8 x 8 = 392 KJ

Height of falling, h = 62 m

Let the time taken by the camera, = t

Now, by the second equation of motion

h = ut + 0.5gt²

62 = 1.2×t + 0.5×9.81×t²

4.905t² + 1.2t - 62 = 0

The compression exerted on the radius at the elbow joint is approximately 70 N.

To calculate the compression exerted on the radius at the elbow joint, we must consider the vector components of the tensile force exerted by the biceps brachii.

The biceps brachii muscle is oriented at a 30° angle to the radius, which means that the force it exerts can be divided into two components: one perpendicular to the radius (the compression force), and one parallel to the radius (the tensile force).

Using trigonometry, we can calculate the perpendicular component of the force as follows:

compression force = 200 N * cos(30°) = 173 N

This means that the compression force is 173 N. However, it's important to note that this is an idealized calculation and does not take into account the effects of other muscles and tendons that may be present at the elbow joint, which can affect the actual compression force.

When the temperature of a gas is raised in a tightly sealed, rigid container, the gas's density will not change. In contrast, when the piston is kept at the same temperature in a container, density decreases.

Charles Law: At constant pressure, the volume occupied by the fixed amount of gas is directly proportional to its absolute temperature.

A gas's mass per unit volume is its density. Volume is directly proportional to temperature, as stated by Charles's law. Volume increases as temperature rises. However, in a rigid container, the gas's mass is unaffected by changes in temperature and volume. As a result, even as the temperature rises, density does not change.

Braking hard in a straight line can be a tricky maneuver, but understanding the weight distribution of the vehicle is key. When braking hard in a straight line, most of the weight of the vehicle will shift onto the front wheels so option a is correct..

This is because the front of the car experiences more friction when braking, while the rear of the car remains relatively stationary. This shift of weight causes the car to decelerate more quickly, and also helps the car to stay balanced and remain in a straight line. The left and right wheels will experience an equal amount of weight during hard braking, as the weight is distributed evenly across the front of the car.

Answer:

The impulse (change in momentum) experienced by the astronaut is given by the product of the force applied and the time over which it is applied. The force applied is given by the rate at which mass is expelled multiplied by the velocity at which it is expelled, which is (35 g * 875 m/s) = 30.625 N.

The impulse experienced by the astronaut is equal to the change in momentum, which is given by the initial mass multiplied by the final velocity, so we can set up the following equation:

m_initial * v_initial = m_final * v_final

where m_initial = 84 kg (mass of astronaut) and m_final = 84 kg (mass of astronaut + 35 g of hot gas).

Solving for v_final, we get:

v_final = m_initial * v_initial / m_final

= 84 kg * 0 m/s / 84 kg

= 0 m/s

So the astronaut's velocity does not change after the thruster is fired because the velocity of the expelled gas is in the opposite direction to the astronaut's motion, they are canceling out.

The magnitude of vector A must be equal to the magnitude of vector B

Vector equals vector b. For two vectors to be equal, their magnitudes and directions must be the same. A vector’s components can never have a magnitude bigger than the vector itself. This is demonstrated by Pythagorean’s Thereom. There is a possibility that a component of a vector has the same magnitude as the vector itself. E.g. A=2x + 0y.

The frequency of the echo from the truck heard by the policeman inside the jeep would be approximately 450 Hz,.

The frequency of the echo heard by the policeman inside the jeep would be different from the frequency of the sound wave emitted by the police siren due to the Doppler effect. The Doppler effect states that the frequency of a wave changes if the source or the observer is in motion relative to the medium through which the wave is traveling.

In this case, the speed of the truck relative to the air is 10 m/s and the speed of the jeep relative to the truck is 20 m/s, so the relative speed of the truck with respect to the air is 10 - 20 = -10 m/s.

The frequency of the echo from the truck heard by the policeman inside the jeep would be given by the following formula:

f = f0 * (v + vr) / (v + vs)

where f0 is the frequency of the sound wave emitted by the police siren, v is the speed of sound, vr is the relative speed of the truck with respect to the air, and vs is the speed of the jeep with respect to the air.

Plugging in the values, we get:

f = 440 Hz * (330 m/s - 10 m/s) / (330 m/s - 20 m/s)

f = 440 Hz * 320 m/s / 310 m/s

f = 440 Hz * 1.03226
