A horizontal disc rotating about a vertical axis makes 100 revolutions per minute. A small piece of wax of mass 10 g falls vertically on the disc and adheres to it at a distance of 9 cm from the axis. If the number of revolutions per minute is there by reduced to 90, calculate the moment of inertia of the disc.

A square loop of side 10 cm and resistance 0.70 ohm is placed vertically in the east -west plane. A uniform magnetic field of 0.10 T is set up across the plane in north-east direction. The magnetic field is decreased to zero in 0.7 sec. at a steady rate. Determine the magnitudes of induced e.m.f. and current during this time interval.

A horizontal platform is rotating with uniform angular velocityy about an vertical axis passing through its centre.At some instant of time,a viscous floud of mass m i s dropped at its centre and is allowed to spread out and finally fall,The angular velocity during this period:

A very small circular loop of area 5xxI0^(-4)m^(2) , resistance 2Omega and negligible inductance is initially coplanar and concentric with a much larger fixed circular loop of radius 0.1m . A constant current of 1A is passed in the bigger loop and the smaller loop is rotated with angular velocity omegarad//sec about a diameter. Calculate induced current in the smaller loop, as a function of time.

The oxygen molecule has a mass of 5.30 xx 10^-26 kg and a moment of inertia of 1.94xx10^-46 kg m^2 about an axis through its centre perpendicular to the lines joining the two atoms. Suppose the mean speed of such a molecule in a gas is 500 m//s and that its kinetic energy of rotation is two thirds of its kinetic energy of translation. Find the average angular velocity of the molecule.

A square loop of side 12 cm with its sides parallel to X and Y axes is moved with a velocity of 8 cm s^-1 in the positive x-direction in an environment containing a magnetic field in the positive z-direction. The field is neither uniform in space nor constant in time. It has a gradient of 10^-3T cm^-1 along the negative x-direction (that is it increases by 10^-3T cm^-1 as one moves in the negative x-direction), and it is decreasing in time at the rate of 10^-3T cm^-1 . Determine the direction and magnitude of the induced current in the loop if its resistance is 4.50 mOmega .
