The mass of an object at the polar region is the maximum.

The mass of an object on the earth is 10 kg. then its mass on the moon would be…………….kg.

The mass of an object is 30 kg, then Its weight on the moon would be ..................N.

The weight of an object on the earth is 98 N, then its mass would be ………. kg

If mass-energy equivalence is taken into account , when water is cooled to form ice, the mass of water should :-(Note: The mass energy of an object is the energy equivalent of its mass , as given by E= mc^(2) , where m= mass of object & c = speed of light)
