The force of gravitation between two bodies does not depend on:
A signal of frequency 20 kHz and peak voltage 5 V is used to modulate a carrier wave of frequency 1.2 MHz and peak voltage 25 V. Choose the correct statement
A wire of variable mass per unit length is \( \mu = \mu_0 x \), hanging from the ceiling as shown in the figure. A small transverse disturbance is produced at its lower end. Find the time after which the disturbance will reach to the other end.
A particle of mass \(10\,\text{g}\) is in a potential field given by \[ V = (50x^2 + 100)\ \text{J kg}^{-1}. \] The frequency of its oscillation in cycles/sec is:
A tank full of water has a small hole at the bottom. If one-fourth of the tank is emptied in $t_1$ seconds and the remaining three-fourths of the tank is emptied in $t_2$ seconds, then the ratio $t_1/t_2$ is
