Answer:
d. NO
Explanation:
As, the potential energy between charge one and two does not depend upon the charge third, so it is very much possible to bring a third charge in from infinity without changing the potential energy of the system. And it does not matter what the sign of the third charge it.
Hence, the correct answer is D.
Answer:
Kinetic energy of bigger rock will be more than that of smaller one.
Explanation:
Kinetic energy of the rock is given by,
Kinetic energy =
As velocity of both the rocks are same. Thus, kinetic energy is directly proportional to the mass of the rock
Kinetic energy ∝ mass
So, For greater mass kinetic energy will be greater and for smaller mass kinetic energy will be smaller.
Hence, Kinetic energy of bigger rock will be more than that of smaller one.
Answer:
B
Explanation:
Nuclear fission is the process of splitting apart nuclei. When nuclei fission energy is released. So much energy is released that there is a measurable decrease in mass, from the mass-energy equivalence. This means that some of the mass is converted to energy.
