Explain Centripetal force??
Sir Isaac Newton suggested that motion in a straight line is most natural, and that deviations from this type of motion are caused by a force pulling the body absent of line. When the force acts on the body from a fixed point, like a body moves in a circle, and the force towards the centre is known as a centripetal force.
When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
1. Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. II. The relationship between an object''s mass m,
Q. If 6.25 X 10 18 electrons flow through a given cross-section in unit time, find the current. Solution: Current I = q / t = ne / t = (6.25 X 10 18X 1.6 X 10 -19) / 1 = 1 A
It is the demagnetising force which is necessary to neutralize completely the magnetism in the magnetism material after the external magnetic field is reduced to zero.

Disadvantages of D.C. Transmission of power 1. Electric power cannot be produced at high d.c. voltages because of commutation problem. 2. The d.c. voltage cannot be stepped
Define the Wave Nature of Sound Sound is called a longitudinal wave because the vibrations are in the same direction as the motion and speed of the wave. This is most easily pi
