A wire 2 m long, 0.1 mm in diameter and has resistance of 20 ohm. Calculate the resistivityof its material.
How does the potential of a bird increases after sitting on a wire due to which, it does not get electric current?
if a object is moving at a velocity of 100kmph and suddenly decelerates at the speed of 10 kmph find the distance traveled
Form of energy that exhibits wavelength behavior as it travels through space. Example: Mircrowave rays, U.V. rays.
