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.

Net force acting on particle of mass 2 kg is 10N in north direction.At t=o, particle was moving eastwards with 10m/s. Find displacement and velocity of particle after 2 seconds.
valu of g above and below the surface of earth
what is the unit of hardness?
Explain Simple Pendulum Simple Pendulum : The A point mass suspended by a weight less and inextensible string to a friction less support is known as a Simple pendulum.
Q. Show Constant Moment Arm? The simplest case is that of a point mass, and the moment of inertia can be immediately written as I = mR 2 ,
Q. How is a galvanometer converted into (a) an ammeter and (b) a voltmeter? A galvanometer is transformed into an ammeter by connecting a low resistance in parallel with it. Th
why the light vibrating in the plane ofincidence is not reflected at Brewster''s angle?
Refractive Index: The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing single medium to another medium. This constant is
