Answer:
Explanation:
The translational kinetic energy depends on the mass and speed of the body, as follows:
While rotational kinetic energy depends on the moment of inertia and the angular velocity of the body, as follows:
. We know that:
Replacing (1) in (2):
Both are mechanical waves (they must have a substance to travel through)
