An ant can have more momentum than an elephant when the elephant is standing still.
Answer: A
Explanation
The momentum is the quantification of the movement done by an object.
It is found to be dependent on the mass of the object and the velocity with which it is moving.
In the present case, the ant has negligible mass compared to elephant so the momentum can be more for ant only when the velocity with which the elephant is moving tends to be zero.
As the velocity of elephant will be zero, the momentum of elephant will be zero so in this criteria, the moving ant will be having more momentum compared to elephant with zero velocity.
So an elephant with zero velocity means the elephant is standing still.
Thus, the condition in which the ant will be having more momentum compared to elephant is when the elephant stands still.

Answer:Increase in the entropy of the universe are the result of chemical reactions
Explanation:
The second law tells about the quality of energy such that any isolated system tends to become more disordered. Any natural Process occurring on its own is irreversible and entropy is increasing for that process.
The entropy of the Universe is increasing which is the result of chemical reactions. Any chemical reaction which increases the number of gas molecules will generate more entropy. Entropy in simple meaning is the order of randomness.
