Question

3. Which of the following
have dimension
M^OL^2T^-2*
quantity​

Answer 1

Answer:

Explanation:

This is actually a tricky one since (at least) two common quantities have this dimension. This can be either an energy or a torque. Let’s go through it.

Force is mass times acceleration. Acceleration is distans per time per time or  LT−2 . Therefore force is  MLT−2 .

Work is force times (parallel) distance so it is  ML2T−2 . Since work is the transfer of energy it is also energy.

Torque is force times (perpendicular) distance so it is also  ML2.

The SI unit for both is newton-meter but in the case of energy we more often call it a joul

Answer 2

Answer:

I never see this dimensional formulla before.

M zero L two T minus two. Means ( L two T minus two)
