Answer:
1. Work Is a type of Physical Activity
2. Power is Basically Having control of Society
Explanation:
The answer is C) rate of change of momentum. The answer is not initial or final momentum as the start and end points are not changing. On the other hand, the time it takes for the ball to change velocity is. This change relates to the change of momentum. Hope this helped :))
Answer:
The man's total displacement is equal to 0.
Explanation:
Given that,
A man ran a 5 mile race. The race looped around a city park and back to the starting line.
We need to find the total displacement of the man.
We know that,
Displacement = shortest path covered
Also,
Displacement = final position - initial position
As it reaches back to its starting line, it means, the displacement is equal to 0.
Hence, the man's total displacement is equal to 0.

Answer:
b)
Explanation:
Let the amplitude of SHM is given as A
so the total energy of SHM is given as
now we know that
a)
kinetic energy is given as
here
so now we have
now its fraction with respect to total energy is given as
b)
Potential energy is given as
so we have
so fraction of energy is given as
