The <em>gaseous state</em> of matter does that. A gas expands to take the shape and volume of whatever you put it into.
A
Excitation to a higher energy state requires energy which is absorbed from the electromagnetic waves applied.
Answer:
Explanation:
Given
Length of beam
mass of beam
Two forces of equal intensity acted in the opposite direction, therefore, they create a torque of magnitude
Also, the beam starts rotating about its center
So, the moment of inertia of the beam is
Torque is the product of moment of inertia and angular acceleration
