Answer:
The answer is B
Explanation:
Because when the both sides aren't balanced one side has to cause motion. (fall down)
Answer:
In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium.

c.The warm surface water results in moist air and more rainfall.
Explanation:
- During upwelling, cold water in the ocean is stirred up and brought to the surface.
- The warmer surface water is then taken into deeper parts of the ocean.
- Upwelling allows for nutrient mixing in the ocean and allows for useful gases to circulate well.
- The warm surface water causes the air to be moisty.
- When the air is carried landward towards the coast, it leads to rainfall when the saturated air releases the water.
- The air then becomes cold and dry and it rises up.
- Therefore, warm surface water results in moist air and more rainfall.

Answer:
Change in potential energy of the block-spring-Earth
system between Figure 1 and Figure 2 = 1 Nm.
Explanation:
Here, spring constant, k = 50 N/m.
given block comes down eventually 0.2 m below.
here, g = 10 m/s.
let block be at a height h above the ground in figure 1.
⇒In figure 2,
potential energy of the block-spring-Earth
system = m×g×(h - 0.2) + 1/2× k × x². where, x = change in spring length.
⇒ Change in potential energy of the block-spring-Earth
system between Figure 1 and Figure 2 = (m×g×(h - 0.2)) - (1/2× k × x²)
= (1×10×0.2) - (1/2×50×0.2×0.2) = 1 Nm.
