Explanation:
<h2>Answer:-</h2>
In case of Figure A and B,
- The work is being done perpendicular against the gravity. And we know that when work is done perpendicular to gravity, then zero work is done.
For Example:-
We also need to know that work done in circular motion is zero.
So, work done by electron to orbit around a proton is also zero.

Answer:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

Answer: Light Refraction
Explanation:
Light rays travel in straight lines. When they strike an opaque surface, the rays bounce, and light is reflected back to your eye so that you see an image. When light strikes a transparent object, some of the light passes through. If that light strikes the object straight on, it continues to travel in a straight line. If the light enters the transparent object at an angle, though, it changes direction, bending.This bending of light is called refraction. Refraction occurs because light entering an object slows down. When it enters at an angle, one side of the light ray enters before the other, slowing down first.Looking from above, an object under water appears larger than it does in air. It's not that the image the light gave our eyes is bigger. It's that the image is actually closer to our eyes, since the light is not passing straight down, but is instead bending relative to the water's surface. Light passing straight down would be perpendicular to the water's surface, like the vertical line on the letter T.
the flow energy from the continental plates. this is due to the sudden movement and temperature caused by various things like temperature change caused by global warming, human pollution, and internal combustion,
movement caused by quakes, global warming, and human partiucipation
