Answer:
pressure is equal to the net amount of force acting per unit area. Dimensional Formulae of force is M1L1T-2 and of area is L2. Therefore Pressure's dimension can be obtained by calculating Force by Area. Dimensional formula of pressure difference is M1L-1T-2.
Answer:
It will be A. So since its 2 times more the kinetic energy. But then you have to square it 2^2 = 4
