Question

Which of the following is not measured in units of energy
a.couple×angle turned through
b.moment of inertia ×(angular velocity)^2
c.force×distance
d.impulse ×second

Answer 1

Answer:

impulse ×second

Explanation:

dimensional formula of couple * angle = ML²T-²

Dimensional formula of energy = ML²T-²

Dimensional formula of force * disance (WORK) =ML²T-²

moment of inertia * (angular velocity )² =ML²T-²

Impulse (F*t)*time= M L T°

Answer 2

Explanation:

option d...

impulse ×second is not equal to energy....
