Two coils, each of self inductance L, are closely wound in series such that the sense of their winding is opposite. The equivalent inductance of the combination is:
A bus moving at a speed of 24 m/s begins to slow at a rate of 3 m/s each second. How far does it go before stopping?
If a plant with green leaves is kept in a dark room with only green light on, which one of the following would we observe?
Two springs are connected to block of mass M placed on a frictionless surface as shown below. If both the springs have a spring constant . the frequency of oscillation of the block is:
Y and Z are two partially reflecting glass sheets, a distance apart in air. White light falls normally on Y. The light emerging from Z is analysed by a spectrometer. A dark band is observed in the spectrometer at a wavelength. The distance must be equal to:
If a small displacement of a system from the rest position (after getting some energy) results in a small bounded motion about the equilibrium position, then the system is in
