Answer:
Stationary
20N
Explanation:
From the graph, we see that the body traveling is on a fixed position. Therefore, it is a stationary body.
The graph given is a position - time curve.
This curve depict a body changing position with given time.
Since the line of the curve is on a single position, the body is not changing position with the passage of time therefore, it is a stationary object.
B. 20N
From Newton's third law of motion we understand that "action and reaction force are equal but oppositely directed".
Since the person is exerting a force of 20N on the balance.
So, the reaction force by the balance is 20N upward.
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.
Im not to good at geography but I think you are correct :)
