Answer:
potential energy
Explanation:
this is because potential energy= mgh
so when m= 2m
p.e. = 2 times the previous value
Therefore , When mass is doubled , Potential energy gets doubled. When mass is halved , Potential energy decreases by half.
Answer: Option (a) is the correct answer.
Explanation:
Photosynthesis is defined as a chemical process in which plants tend to make their own food in the presence of sunlight, water and carbon dioxide.
During this process, product formed by the plants is glucose and oxygen.
The chemical reaction equation for photosynthesis is as follows.

Therefore, we can conclude that out of the given options the correct equation is as follows.
