1.

(A^(2))/("mass")has the dimensions of kinetic energy. Then A has the dimensions of

Answer»

pressure
torque
MOMENT of inertia
IMPULSE

Solution :`(A^(2))/(mass(m))= KE= (1)/(2)mv^(2)` or `A^(2)= (1)/(2)m^(2)v^(2)`
`:.` A has the DIMENSIONS of `mv= [MLT^(-1)]`which are the dimensions of impulse `(F xx t)`.
