Question

Prove that energy,density and pressure has same dimension

Answer 1

For Pressure,  P= F/A = ma/A=mv/At =ms/At²=[M ^1 L^-1 T^-2]

.....Try to go deep into the equation unless you'll reach for very basic one like Mass, Length(or area), Time.......

 I HOPE you understand and can get the dimensions of energy and density too by this method............

Don't forget their answer would also be equal to same as that........
