Explain newtons cradle-A typical Newton's cradle consists of metal balls of identically sized in a series suspended in a metal frame ,so that they are just touching each other at rest. Each ball is gently attached to the frame by 2- wires of equal length and angled away from each other. This restricts the pendulum's movements to the same plane.
Newtons Cradle
1 Farad: One farad is described as the capacity of that capacitor which keeps a charge of 1 coulumb, if the potential difference among the plates is one volt. It's equation
Coulomb: Coulomb is the fundamental unit of charge. It is explained as the charge required to obtain 9?109 newton of force among two equal charges separated at a distance of one m
composition of two SHM at right angle to each other and having time period in the ratio of 1: 2
EXAMPLES OF IT
