Explanation:
From a new Moon, when the Moon is situated in orbit between the Earth and the Sun with its dark side in shadow facing towards us, the amount of lunar surface visible from the Earth increases through waxing crescent, first quarter and waxing gibbous phases until it becomes full.
Or
The new moon is the phase that is invisible to us here on Earth because the moon is between the earth and the sun, and its illuminated side is facing away from us. A solar eclipse occurs when the moon moves in front of the sun, blocking it from our view on Earth.
The first question's answer is :
If, F=ma
Then, 15N= 2.1kg (a)
15/2.1=a
7.14=a
Therefore, acceleration = 7.14m/s^2
sorry I am not sure about the second question :-(
Answer: Please find the answer in the explanation
Explanation:
Under what circumstances does distance traveled equal magnitude of displacement?
When a body's motion is linear in one direction. Or a body moving in a straight line without turning back.
What is the only case in which magnitude of displacement and distance are exactly the same?
When the body is moving in a straight line with without changing direction or without turning back.
