Answer: This is called backscatter which refers to the ability of big waves to reflect the energy in order to give back the signal .
Explanation:
What is meant by backscatter?
Backscatter is the process where by the waves or signal is reflected back to the original direction and get scattered in all directions.
Backscatter allows us to receive signal and be able to view all the channels that are connected through the satellite.

At 1.75 m high, PE = 1543.5 J
ANSWER:
D) centripetal acceleration.
STEP-BY-STEP EXPLANATION:
When a body performs a uniform circular motion, the direction of the velocity vector changes at every instant. This variation is experienced by the linear vector, due to a force called centripetal, directed towards the center of the circumference that gives rise to the centripetal acceleration.
Therefore, the answer is centripetal acceleration.
