EXAMPLES:
(i) A book lying on the table remains at rest until it is listed or pushed by exerting a force.
(ii)A rolling ball on the ground comes to rest after covering some distance. The ball has not contradicted the first law of motion due to the ball has been stopped because of friction of ground and resistance of air. If we delete these frictional forces, once the ball set into motion will carry on its motion for ever.
The greatest induced EMF will occur in a straight wire moving at constant speed through a uniform magnetic field when the angle between the direction of the wire's motion and the d
STABLE EQUILIBRIUM If object is in stable equilibrium and if we displace object to a very little displacement dr then it will return back to starting position. UNSTABLE EQU
1 Coulumb Charges: 1 coulumb charge is that amount of charge which when placed 1 m from an identical charge in vacuum which repels it with a force of 8.99 × 109 N.
to derive expreation for magnitude & direction for the resultant which two are acting at a point
When a small size magnet is laid in two uniform magnetic fields and which are at right angles to each other, the magnet comes to rest at an angle Φ with respect to B h like that
If we have to strain a ferromagnetic crystal along certain direction, we would change the inter atomic spacing not only along this direction but also in other direction. And hence
Get an expression for work done during reversible isothermal expansion. Get the terms open, isolated and closed system. Give examples.
What is heat
It is the ratio of the internal electric field induced by the charges on the surface on the dielectric when an external field applied to the polarization of the dielectric.
The force applied at A is P30 Newton's, and P31 and P32 are dimensions in mm. A mechanic uses his left hand to support the wrench at point B. Determine the upward force required a
