If 600J of energy is spent in increasing the speed of a wheel from 60 rpm to 240rpm the M.I.of the wheel is.[(pi^(2)=,10) (A) "2kgm^(2) (B) 3kgm^(2) (C) 4kgm^(2) (D) 5kgm^(2)

An energy of 484 J is spent in increasing the speed of a flywheel from 60 rpm to 360 rpm. Calculate moment of inertia of flywheel.

To increase the speed of a flywheel from 60 rpm to 360 rpm, energy of 490 J is spent. Calculate the moment of inertia of wheel.

A wheel increases its speed from 60 rpm to 120 rpm in 10 s. Number of rotation made by it in 10 s is

The speed of the wheel of an engine changes from 600 rpm to 1200 rpm in 5 s. Then its angular acceleration in rad//s^(2)

A fan of moment of inertia 0.6kgm^(2) is moving with a speed of 0.5 r.p.s. The angular momentum of the fan is

What is the angulr momentum of the electron in the fourth Bohr orbit in the hydrogen atom? [h/(2pi) = 1.055 xx 10^(-34) kg.m^(2)//s]

A flywheel is rotating at an angular speed of 150 rpm. If the moment of inertia of the flywheel somehow decreases from 10kgm^(2) to 4kgm^(2) , then what will be the new angular speed of the flywheel?

When the speed of a flywheel is increased from 240 r.p.m. to 360 r.p.m., the energy spent is 1936 J. What is te moment of inertia of the flywheel?

A disc of moment of inertia 9.8//pi^(2)kg m^(2) is rotating at 600 rpm. If the frequency of rotation changes from 600 rpm to 300 rpm, then what is the work done ?
