In the circuit shown in the figure, the AC source gives a voltage \( V = 20\cos(2000t) \). Neglecting source resistance, the voltmeter and ammeter readings will be:

In the following circuit, the equivalent resistance between X and Y is ...... \( \Omega \):

A solid sphere of 80 kg and radius 15 m moving in a space becomes a circular disc of radius 20 m in 1 hour. The rate of change of moment of inertia in this process is:

A direct current of \(6A\) is superimposed on an alternating current given by \( I = 10\sin \omega t \) flowing through a wire. The effective value of the resulting current will be:

Transverse waves of the same frequency are generated in two steel wires A and B. The diameter of A is twice that of B, and the tension in A is half that in B. The ratio of the velocities of the waves in A and B is:

Which one of the following graphs represents the variation of electric potential with distance \( r \) from the center of a non-conducting charged sphere of radius \( R \)?

For an insulator, the forbidden energy gap is:

A submarine A, traveling at \(17 { m/s}\), is being chased along the line of its velocity by another submarine B, traveling at \(34 { m/s}\). Submarine B sends a sonar signal of \(600 { Hz}\) to detect A and receives a reflected sound of frequency \( v \). The value of \( v \) is: \[ {[Speed of sound in water} = 1500 { m/s}] \]

A transistor is connected in common-emitter (CE) configuration. The collector supply is 8V and the voltage drop across a resistor of 500 \( \Omega \) in the collector circuit is 0.6V. If the current gain factor \( \alpha \) is 0.96, find the base current.

Four holes of radius \(5\) cm are cut from a thin square plate of \(20\) cm side and mass \(1\) kg. The moment of inertia of the remaining portion about the \(Z\)-axis is:

An achromatic convergent doublet of two lenses in contact has a power of +5D. The power of the converging lens is +6D. The ratio of the dispersive power of the converging and divergent lenses is:
