An ideal diode is connected in series with a capacitor. The free ends of the capacitor and the diode are connected across a \(220 \mathrm{~V}\) ac source. Now the potential difference across the capacitor is :

A particle executes a simple harmonic motion of amplitude \(\mathrm{A}\). The distance from the mean position at which its kinetic energy is equal to its potential energy is

Which of the given dimensional formula represents heat capacity

Find the value of '\(n\)' in the given equation \(P=\rho^n v^2\) where '\(P\)' is the pressure, '\(\rho\)' density and '\(v\)' velocity.

In the Young's double slit experiment \(n^{\text {th }}\) bright for red coincides with \((n+1)^{\text {th }}\) bright for violet. Then the value of '\(n\)' is: (given: wave length of red light \(=6300^{\circ} \mathrm{A}\) and wave length o...

In a single slit diffraction experiment, for slit width '\(\alpha\)' the width of the central maxima is '\(\beta\)'. If we double the slit width then the corresponding width of the central maxima will be:

When light wave passes from a medium of refractive index '\(\mu\)' to another medium of refractive index '\(2 \mu\)' the phase change occurs to the light is :

The width of the fringes obtained in the Young's double slit experiment is \(2.6 \mathrm{~mm}\) when light of wave length \(6000^{\circ} \mathrm{A}\) is used. If the whole apparatus is immersed in a liquid of refractive index 1.3 the new fr...

A string of length \(25 \mathrm{~cm}\) and mass \(10^{-3} \mathrm{~kg}\) is clamped at its ends. The tension in the string is \(2.5 \mathrm{~N}\). The identical wave pulses are generated at one end and at regular interval of time, $$\Delta ...

The power of a gun which fires 120 bullet per minute with a velocity \(120 \mathrm{~ms}^{-1}\) is : (given the mass of each bullet is \(100 \mathrm{~g}\))
