Question

Out of the following pairs ,which one does not have identical dimensions?
1.moment of inertia and moment of a force
2.work and torque
3.angular momentum and planck's constant
4.impulse and momentum

Answer 1

Answer:

The moment of inertia and the moment of a force does not have identical dimensions.

Explanation:

The sum of the masses of its constituent particles and the square of their relative distances from the axis of rotation equals the moment of inertia of a body about a certain axis.

A force's moment is a measurement of its proclivity to induce a body to revolve around a given point or axis. This is distinct from a body's inclination to move or translate in the force's direction.
