If an energy of 684 J is needed to increase the
speed of a flywheel from 180 rpm to
360 rpm, then find its moment of inertia.

The truth table given below corresponds to logic gate.

A particle executing simple harmonic motion
along a straight line with an amplitude A,
attains maximum potential energy when its
displacement from mean position equals

The bob of a simple pendulum is a spherical
hollow ball filled with water. A plugged hole
near the bottom of the oscillating bob gets
suddenly unplugged. During observation, till
water is coming out the time period of
oscillation would

The position of the direct image obtained at
O, when a monochromatic beam of light is
passed through a plane transmission grating
at normal incidence is shown in figure.
The diffracted images A, B, and C correspond
to the first, second and ...

A string fixed at both ends vibrate in 5 loops
as shown in the figure. The total number of
nodes and anti-nodes respectively are

The range of a projectile is 100 m. Its kinetic
energy will be maximum after covering a
distance of

When a force F = 17 \(-\) 2x + 6x\(^2\)N acts on a body of mass 2 kg and displaces it from x = 0 m to x = 8 m, the work done is

A rifle bullet loses \(\left(\frac{1}{25}\right)\)th of its velocity in passing through a plank. The least number of such planks required just to stop the bullet is

A uniform chain has a mass m and length \(l\).
It is held on a frictionless table with
one-sixth of its length hanging over the edge.
The work done in just pulling the hanging
part back on the table is
