Answer the question who r brilliant

Answer 1

Pound of rocks is heavier

Answer 2

Heaviness is weight of a substance.

Weight = mg

Both are of same mass “m”.

Acceleration due to gravity “g” is same for every substance at the surface of a planet.

So, both are equally heavy.

P.S
No need to be brilliant for this question. Just knowing basics of physics is enough. In future don’t use such terms in your question.
