The stopping potential in the photoelectric effect depends on:

In a series LCR circuit, the resonant frequency is 1000 Hz. If both the inductance and capacitance are doubled, the new resonant frequency is

A circular disc of mass M and radius R has moment of inertia I about its diameter. About an axis perpendicular to the disc and passing through its edge, the moment of inertia is:

The refractive index of glass is 1.5 and that of water is 4/3. The refractive index of glass with respect to water is:

Three identical resistors each of resistance R are connected in parallel. Their equivalent resistance is:

Three particles of masses 1 kg, 2 kg, and 3 kg are placed at the corners of a right triangle with vertices at (0, 0), (4, 0), and (0, 3) meters respectively. The coordinates of the center of mass are:

Kirchhoff's second law (the loop rule) is based on the conservation of:

Two identical springs of spring constant k are connected in parallel. The effective spring constant is:
