A bomb dropped from an air plane explodes in mid air - (a) its kinetic energy increases (b) its total energy increases (c) its total energy decreases (d) none of these

A bomb dropped from an aeroplane explodes in air. Its total :

If the velocity an object increases 4 times, its kinetic energy increases

If the momentum of a body is increased n times, its kinetic energy increases

Kinetic energy of a body decreases with the increase in mass.

If the kinetic energy of a body increases by 125% , the percentage increases in its momentum is

An electron in a hydrogen atom makes a transition such that its kinetic energy increases, then

As an electron makes a transition from an excited state to the ground state of a hydrogen like atom/ion (a) kinetic energy, potential energy and total energy decrease (b) kinetic energy decreases, potential energy increases but total energy remains same (c ) kinetic energy and total energy decrease but potential energy increases (d) its kinetic energy increases but potential energy and total energy decrease
