EXPERTS PLZ HELP ME Is the moment of inertia of disc and ring are (mr 2 )/2 and mr 2 respectively?? and if yes how can the moment of inetial of ring greater than that of disc ??
Yes, its true. The moment of inertia of a disc and a ring about an axis perpendicular to their plane are and resspectively. Here you have to notice in both the cases we are taking the mass...

See the moment of inertia is proportional to r 2, for same mass ,as the mass is concentrated more farther from the ring it will have greater moment of inertia.

A body of mass 100g is moving with a velocity of 10m/s along the positive x-direction. At time t=0, when the body is at x=0, a constant force of 0.8N acting along the negative x-direction...
We get retardation here, a = – 0.8/0.1 = 8 m/s^2. final velocity at t=5s, v = 10i -8i * 5 = 10i – 40i = -30i Now at t=3 apply 2 nd law of eqn. and get the value of x.

What is modulation index and what are the equations for finding it?
Modulation index ( μ) is the ratio of amplitude of message signal (A m ) to that of the carrier wave (A c ) that is, μ = A m /A c = ((A max -A min )/2)/((A max +A min )/2) = (A max -A min...
