In `C^(12)` atom if mass of `e^(-)` is doubled and mass of proton is halved, then calculate the percentage change in mass no. of `C^(12)`

Mass of a moving body is doubled and velocity is halved . What will be the change in momentum ?

The percentage change in the pressure of a given mass of a gas filled in a container at constant temperature is 100%. Calculate the percentage change in its volume.

Calculate the percentage mass of water in crystals of washing soda.

The percentage change in the volume of the given mass of a gas at constant temperature is 50% (increases). Calculate the percentage change in the presure of the gas.

The ratio of the mass of the proton to the mass of the electron is

The distance between the carbon atom and the oxygen atom in a carbon monoxide molecule is 1.1 Å . Given, mass of carbon atom is 12 a.m.u. and mass of oxygen atom is 16 a.m.u., calculate the position of the centre of mass of the carbon monoxide molecule

The mass of a H-atom is less than the sum of the masses of a proton and electron. Why is this?

It is known that atom contain protons. Neutrons and electrons. If the mass of neutron is assumed to half of its orginal value where as that of proton is assumed to be twice of its original value then the atomic mass of ._(6)^(14)C will be :-
