Question

which is heavier ? a Pound of feathers or a Pound of rocks​

Answer 1

Answer:

Definitely, a pound of rocks is heavier than a pound of feathers.

Answer 2

Answer:

A pound of rocks on earth (not in a vacuum) is slightly heavier than a pound of feathers; this is because 'rocks' obviously have a higher density than 'feathers', assuming the feathers are loosely held and not tightly packed.
