The law of gravitation states that things closer to the core of gravitation, have a larger force pulling down on them. In relation of you to your desk, you and the desk are both drawn downwards towards the center of gravity.
Answer:
v = 12.86 km/h
v = 3.6 m/s
Explanation:
Given,
The distance, d = 13.5 km
The time, t = 21/20 h
= 1.05 h
The velocity of a body is defined as the distance traveled by the time taken.
v = d / t
= 13.5 km / 1.05 h
= 12.86 km/h
The conversion of km/h to m/s
1 km/h = 0.28 m/s
12.86 km/h = 12.86 x 0.28 m/s
= 3.6 m/s
Hence, the velocity in m/s is, v = 3.6 m/s
Because sound waves don't travel through the vaccume of space. Hope this helped
Answer:
Initial position of a body is the position of the body before accelerating or increasing its velocity the position changes and then that position is the final position.

Answer:
clockwise
Explanation:
We shall apply Lenz's law to find the direction of induced current in case magnetic field changes. According to this law , direction of current induced is such that it will try to oppose the cause which produces the induced current .
In the present case, downward magnetic field decreases so current will be such that downward magnetic field increases . It can happen when clockwise current is induced. So clockwise current will be induced.
