1. Homework Statement [/b]
The force you exert on the Earth is insignificant compared to the force the Earth exerts on you. (True or false)
The attempt at a solution[/b]
I believe that this is false based upon Newton's third law--shouldn't the forces be equal and opposite?
2. Ice cube floating in glass of water--water level increases when it melts.
Is this also false? Unless the ice cube is being held under the water, shouldn't the density and volume differences cancel out since the mass does not change? (Assuming the ice is chemically identical to the water?)
