A capacitor (condenser) is used in an electrical circuit in order to
A capillary tube is kept vertical in a beaker containing liquid. The height to which the liquid rises by capillary action is increased if
A car accelerates uniformly from 18 kmph to 72 kmph in 5 s. The acceleration of the car (in m/s^2) is:
A car and lorry are both moving with equal kinetic energy. If equal breaking force is applied on both, then before coming to rest the
A car is moving on a road at a uniform speed of 60 km/h. The net resultant force on the car is
A car starts from rest and moves on a straight road with a uniform acceleration of 10 m/s2 for the first 10 s. During the next 10 s, the car moves with the velocity it has attained. What is the total distance covered by the carin 20 s?
A circular loop of wire is rotated at constant angular speed about an axis that makes an angle q with a constant magnetic field as shown in figure. The emf induced in the coil will be zero at all times if
A coating of dust on a computers main circuit boards has this probable consequence
A coil having an inductance of 100 mH is carrying a current of 100 A. If the current is reduced to zero in 0.02 sec, the self induced e.m.f will be
