Suppose, the same angular momentum is transferred to two rotating bodies of different moment of inertia , how will you compare t
Sonbull [250]

Answer:

As per the law of conservation of angular momentum, the angular velocity will be higher for the body with a lower moment of inertia and vice versa.

Explanation:

Angular momentum L of a body is given by:

L=I\times \omega

Now when the same angular momentum is transferred to two different bodies with different moment of inertia, the body with a higher moment of inertia will have lower angular velocity and vice versa.

A spring has a spring constant of 20 N/m. How much potential energy is stored in the spring as it stretched 0.20 m
makkiz [27]
The elastic potential energy (Ep) is given by Ep = \frac{1}{2}*k*x^2

Data: 
Ep = ? (Joule)
k = 20 N/m
x (displacement) = 0.20 m

Solving:
Ep = \frac{1}{2}*k*x^2
Ep = \frac{1}{2}*20*0.20^2
Ep =  \frac{20*0.04}{2}
Ep =  \frac{0.8}{2}
\boxed{\boxed{Ep = 0.4\:J}}\end{array}}\qquad\quad\checkmark
