We can assume that man-hour is a unit of power. Both man-hour and kilowatt-hour are units for power. The difference between them is that the second one can be quantified while the first one cannot.

Power has a wide range of meanings in everyday life, but in physics, it has a very specific meaning. Power is defined to be work over elapsed time. This can be mathematically expressed as P = W/t where P is power, W is work, and t is elapsed time.

If work is done faster, the power is higher. Power is smaller when work is done slower.

The standard unit used to measure power is watt (symbolized W, not to be confused with work which is a quantity, not a unit). 1 kilowatt-hour is equal to 1,000 watts. Another widely-used unit of power is the horsepower (symbolized hp).

The bird's speed immediately after swallowing is 6.91 m/s

The conservation of momentum states that, within a few problem domains, the quantity of momentum remains regular; momentum is neither created nor destroyed, but best modified through the movement of forces as described by means of Newton's laws of motion.

Calculation:-

Mass of bird m₁ = 280 g = 0.28 kg

velocity v₁ = 6 m/s

mass of insect m₂ = 11g = 0.011 kg

velocity = 30 m/s

applying conservation of momentum considering bird and insect as a close system

m₁v₁ + m₂v₂ =  m₁v₁ + m₂v₂ V

V =  m₁v₁ + m₂v₂ /m₁ + m₂

  = (0.28 × 6 + 0.011 × 30) /  0.28 +0.011

  = (1.68 + 0.33) / 0.291

   = 2.01 / 0.291

   = 6.91 m/s

The regulation of conservation of momentum states that in an isolated machine the full momentum of or more bodies appearing upon each other stays regular except an outside force is applied. therefore, momentum can neither be created nor destroyed.

The graph of the vertical component of the ball's velocity is in the attachment

Speed is the distance moved per unit time.

Velocity is the total displacement per unit time of an object.

Since a 0.1 kg ball is kicked from the edge of a cliff so that it attains a launch speed of 20 m/s at an angle of 37 to the horizontal, as shown above. To determine the vertical component of velocity,we use the equation of motion

v = u - gt where

So, substituting the values of the variables into the equation, we have

v = u - gt

v = u'sinФ - gt

v = (20 m/s)sin37° - (9.8 m/s²)t

v = (20 m/s) × 0.6018 - (9.8 m/s²)t

v = 12.04 m/s - (9.8 m/s²)t

So, for the first 3 seconds, we have

for t = 0 s

v = 12.04 m/s - (9.8 m/s²) × 0 s

v = 12.04 m/s - 0 m/s

v = 12.04 m/s

for t = 1 s

v = 12.04 m/s - (9.8 m/s²) × 1 s

v = 12.04 m/s - 9.8 m/s

v = 2.24 m/s

for t = 2 s

v = 12.04 m/s - (9.8 m/s²) × 2 s

v = 12.04 m/s - 19.6 m/s

v = -7.56 m/s

for t = 3 s

v = 12.04 m/s - (9.8 m/s²) × 3 s

v = 12.04 m/s - 29.4 m/s

v = -17.36 m/s

So, we plot the graph of the vertical component of the ball's velocity using the equation v = 12.04 m/s - (9.8 m/s²)t

The total amount of energy remains the same. It just changes from one form to another as the person swings back-and-forth. Statement (C) is true.

Energy is the ability to perform work in physics. It could exist in several different forms, such as potential, kinetic, thermal, electrical, chemical, radioactive, etc. Additionally, there is heat and work, which is energy being transferred from one body to another.

When Manuel was watching his younger siblings on the swing set; the motion of swinging is a kind  of simple harmonic motion where total energy remains conserved. But kinetic and potential energy are continuously exchanged in simple harmonic motion.

Potential energy is at its peak and kinetic energy is zero when you are farthest from the equilibrium point. The kinetic energy is at its peak and the potential energy is zero at the equilibrium point. The oscillating body's kinetic and potential energy values change at other points in its motion. So, the total amount of energy remains the same. It just changes from one form to another as the person swings back-and-forth.

From Newton's law of universal gravity, we understood that the force of attraction / repulsion between two objects is given as:

F = GM₁M₂ / r²

Where

With the above formula, we can determine the distance between the two asteroids. This is illustrated below:

F = GM₁M₂ / r²

1030 = (6.67×10¯¹¹ × 1.41×10¹⁴ × 1.41×10¹⁴) / r²

Cross multiply

1030 × r² = 6.67×10¯¹¹ × 1.41×10¹⁴ × 1.41×10¹⁴

Divide both sides by 1030

r² = (6.67×10¯¹¹ × 1.41×10¹⁴ × 1.41×10¹⁴) / 1030

Take the square root of both sides

r = √[(6.67×10¯¹¹ × 1.41×10¹⁴ × 1.41×10¹⁴) / 1030]
