Explanation:
The average speed

Time to pass patch

The acceleration

Hence,
that the acceleration in the sandy patch.

What do you understand by the acceleration? </h3>
Any procedure where the velocity varies is referred to as acceleration. There are only two ways to accelerate: changing your speed or changing your direction, or changing both. This is because velocity is both a speed and a direction.
The meter per second per second (m/s2) unit of acceleration. Definition. The newton is the unit of force that, when applied to a mass of one kilogram, results in a one-meter-per-second acceleration.
Changing the speed at which an object is travelling is what acceleration is all about. A substance is not accelerating if its velocity is not changing.

"Ocean waves" is the only example of mechanical waves on that list.
The other three choices are all electromagnetic waves.
Hello
I think some details of the question are missing. However, I believe you are referring to a bob following some circular path. Therefore, the answer is "no": in fact, the centripetal force is equal on the earth and on the moon.
Keep in mind that the centripetal force is given by

where m is the mass, v the tangential velocity and r the radius of the circular motion. The mass m of the bob is the same on the earth and on the moon, so the centripetal force is the same.
