Q. A small candle, 2.5 cm in size is placed at 27cm in front of a concave mirror of radius of curvature 36cm. At what distance from the mirror should a screen be placed in order t
what is the magnetic field at a distance l from the centre of the circle of radius r which carries a current i
Motion of simple pendulum. Simple Harmonic Motion: It is a type of vibratory motion in which body has an immediate acceleration whose magnitude is directly proportional to the
A transformer takes a current of 0.8A when its primary is connected to a 240 volt, 50Hz supply, the secondary being on open circuit. If the power absorbed is 72 watts, Determi
The physical value which does not depend on any other physical quantity is known as a fundamental physical quantity like length; mass and time are known as fundamental units.
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
Centrifugal pseudoforce A pseudoforce which occurs while one is moving in consistent circular motion. One feels a "force" directed outward from the center of motion.
Q What is Tyndal scattering? Tyndal scattering- When light passes throughout a colloidal solution its path is visible inside the solution. This is for the reason that the
