    Energy (J) = kg.m^2.s^-2 A. What is the unit of couple? Nevertheless angle has a unit of rad. I think the answer is A. B. Moment of Inertia (I) = kg.m.s^-1; (angular velocity)^2 = rad^2.s^-2. I think the answer is B too. C. Not the answer. Obviously this is J. D. Impulse (I) = kg. m.s^-1; time (t) =s. I think the answer is D. E. Not the answer. Obviously this is J. What do you think the answer? I think the answer is between A, B, and D. Please help.
