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.

Q. Illustrate what does hull speed mean? Answer:- Hull speed- It is the theoretical limit of a sail craft's speed. It is able to be approximated by the following formula
Static electricity: If electrons are removed from one material and placed on another, or if they are moved from one region of a piece of material to another, we have a separati
Electromagnetic waves are transverse waves; that means magnetic vector and electric vector, propagation vector are perpendicular to each other. Prove the statement mathematically.
Q. Define: ampere's circuital law. The line integral → → for a closed curve is equivalent to μo timesthe net current Io B . d l By the area bounded by the curve.
A truck engine mass 5000kg is pulling a trailer mass 1000kg along a level track at an acceleration of 0.01.Resistance are 10N per 1000for the engine 5N per 1000kg for the trailer.
Can you explain Ohms Law? Ans. If Temperature remains constant then current flow is directly proportional to applied Voltage. I ∝ V, I = V/R (resistance of the conductor)
Explain the Vector Addition of Velocity Of course the velocity is relative to how you indicate the position d. If you are moving in water that is itself moving, then your full
