By keeping moment of inertia of a body constant, if we double the time period, then angular momentum of body
In series L-C-R circuit, the capacitance is changed from C to 2C. The inductance should be changed from L to ... to obtain same resonance frequency.
The path difference produced by two waves is 3.75 $\mu$m and the wavelength is 5000 $\mathring {A}$. The point is
The simple pendulum acts as second's pendulum on earth. Its time on a planet, whose mass and diameter are twice that of earth is
The energy stored per unit volume in copper wire, which produces longitudinal strain of 0.1% is $(Y =1.1\times10^3 Nm^{-2})$
An electron projected in a perpendicular uniform magnetic field of $3 \times 10^{-3} T, $ moves in a circle of radius 4 mm. The linear momentum of electron $(in \, kg-ms^{-1}) $ is
Consider a short magnetic dipole of magnetic length 10 cm. Its geometric length is

The binding energy of a satellite of mass m in a orbit of radius r is (R = radius of earth, g = acceleration due to gravity)
Two perfect gases at absolute temperatures $T_1$ and $ T_2$ are mixed. There is no loss of energy. The temperature of mixture of masses of molecules are $ m_1$ and $ m_2$ and the number of molecules in the gases are $n_1 $ and $ n_2 $ respectively, is

The displacement of a particle performing simple harmonic motion is given by, x=8sin$\omega t+6cos \omega t$, where distance is in cm and time is in second. The amplitude of motion is
The minimum phase difference between two simple harmonic oscillations, $ \, \, \, \, \, \, \, \, y_1 =\frac{1}{2}sin \omega t +\frac{\sqrt 3}{2} cos \omega t$ $ \, \, \, \, \, \, \, \, \, \, \, y_2 =sin \omega t +cos \omega t$ is
Two light rays having the same wavelength $\lambda$ in vacuum are in phase initially. Then the first ray travels a path $L_1$ through a medium of refractive index $n_1$ while the second ray travels a path of length $L_2$ through a medium of refractive index $n_2$. The two waves are then combined to produce interference. The phase difference between the two waves is
Turning effect is produced by
