The intensity of the sound wave is defined as the ratio between the power of the wave and the area through which the wave passes:
where
I is the intensity
P is the power
A is the area
If we use the data of the problem,
and
, we find the intensity of the sound wave:
Force your doing it purposely and acceleration it’s just happening
Angular momentum is conserved in the above examples such as the ice skater, the torque or the rotating effect of the force is almost equal to zero because there is negligible friction between the skates and the ice.
<h3>What is principle of conservation of angular momentum?</h3>
The principle of conservation of angular momentum states that the total angular momentum acting on an object is constant, provided there is no external torque acting on the object.
Angular momentum of a system is conserved as long as there is no net external torque acting on the system.
<h3>Examples of conservation of angular momentum</h3>
- the spinning ice skater
- someone spinning in an office chair
- a child spinning on roller coaster
Thus, angular momentum is conserved in the above examples such as the ice skater, the torque or the rotating effect of the force is almost equal to zero because there is negligible friction between the skates and the ice.

Hi there! Hopefully this helps!
Answer: A force applied to a machine to an object is the <em>effort force</em>.
