Answer:
According to <em>Newton's first law of motion:</em>
<u>An object in motion tends to remain in motion unless an external force acts upon it.</u>
<u>It stays in motion with the same speed and goes in the same direction.</u>

This imply that the force applied by the gravity of the earth on the person, is equal to the force applied by the person on the earth.
According to the Newton's third law, for every force there is an equal reaction force, in the case of person standing on the earth, the gravity of the earth pulls the person by the same magnitude as the force applied by the person on the earth (which is equal to the weight of the person)..
Answer:
The H-R diagram can be used by scientists to roughly measure how far away a star cluster or galaxy is from Earth. This can be done by comparing the apparent magnitudes of the stars in the cluster to the absolute magnitudes of stars with known distances (or of model stars).

Answer:
B v1= 12.5m/s
Explanation:
As the acceleration is constant and time taken is also same and distance covered is halfed so the speed will also be halfed.
