Impluse = ft.

Momentum of force = ft, so both are dimensionally identical.

Please reply me. If I am wrong.

hv = Joule & Hence h= Joule/v(frequency) = joule*time.

Angular momentum = mvr = joule*time.

Due to the description of torque. I can say that the exact answer is 'C'. (FULLY SATISFIED).

Could anybody please explain how planck's constant and angular momentum has same dimensions?

impulse = ft = Ns is the unit.

Moment of a force = f * distance = Nm is the unit.

Mv^2 has dimension = MLT-1.

Energy has dimension = ML2T-2.

So, How they equals?

Strom said:   1 decade ago
Mvr = Mv^2(r/v).

Mv^2 has dimension of energy.

(R/v) has dimension of time.

Distinguish between impulses and momentum and how they are related?

Seema said:   1 decade ago
How the dimension of angular momentum - joule* time?
