Answer:
The ideal transformer has no resistance, but in the actual transformer, there is always some resistance to the primary and secondary windings. For making the calculation easy the resistance of the transformer can be transferred to the either side.
Why this would occur is because when the ground shakes under the water it causes the earth to move, which means earths plates are shaking which can lead to what?
Freefall is when you don't have any control over your body, you have gravity pulling you down to the center of the earth, while weightlessness you have the ability to float, go down, move side to side. In weightlessness you have zero gravity, but while your freefalling you are in gravity.
Hope I was able to help!
Answer:
Only a decreasing gravitational force that acts downward
Explanation:
The gravitational force is the gravitational pull which attract a mass of smaller size by the mass of a bigger size. It is the force which attract two masses close to each other.
In the context, when a ball is tossed up from the surface of an asteroid that have no atmosphere, the ball rises up and then falls back to the surface of the asteroid. The ball falls back because the gravitational pull of the asteroid pulls back the ball to its surface. Thus a decreasing gravitational force acts on the ball in the downward direction while the ball is in its way up.
It gains speed and kinetic energy, as it loses potential energy.
