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.

a) What is the magnitude of a point electric charge chosen so that the electric field because of it at a point 50 cm away has magnitude 2.0 NC¯¹ ? (b) Get a mathematical expre
c). at what speed does it hit the ground? d). what total length of time is the ball in the air
In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use
Is photon a particle or a wave? What is its rest mass? Can X-ray generate photoelectric effect? Determine the work function of a metal production photo electrons with X-rays of
A block of wood initially at rest slides down an inclined plane. Neglecting friction, the kinetic energy of the block at the bottom of the plane is: a) All converted into h
TA=300 TB=400 rA= rA=6.3(10)^12
how the direction of friction is obtained?
Q. In the given circuit, calculate the potential differences across each resistor Solution : i) R s = R 1 + R 2 + R 3 = 10Ω ii) Current in circuit I = V/R s
The capacitors can be classified on the basis of nature of value, type of dielectric material used and polarity. On the basis of nature of value: Fixed value capacitor
