A pendulum oscillates 40 times in 4 seconds. Find its time period and frequency.
Frequency of oscillations is the number of oscillations of a vibrating object per second. Therefore frequency is = 40 vibrations /4 seconds= 10 Hertz. Time period is the time required to...

A positively charged particle (alpha-particle) projected towards west is deflected towards north by a magnetic
Since the positively charged particle (alpha-particle) projected towards west, so the direction of current is towards west. Now the deflection is towards north, so the force is towards north' Now...

A particle executes simple harmonic motion with a frequency v. The frequency with which the kinetic energy oscillates is
The correct answer is (c) 2 v EXPLANATION: Between one extreme position to another i.e. in half the time period the K.E. increases from zero to maximum (at the mean position) and again...

The energy contained in a small volume through which an electromagnetic wave is passing oscillates with (a) zero frequency
The energy per unit volume contained in electromagnetic waves is U = 1/2ɛE^2 + B^2/2μ If the electric field is represented by a form E_o cos( wt - kx) the energy can...
