Yes magnetism more important for iit because the weight of this magnetism is very hign so be careful about this magnetism chapterAll the best for your preparation
A rod follower AB is subjected to a vertical up and down movement while resting on a circular contour of radius 30cm of a cam.the cam moves to the right with a velocity of 5 cm/s a
CONSERVATION OF ENERGY 1. Potential energy is, as the word suggests, the energy "locked up" up somewhere and which can perform work. Potential energy Potential energy can b
Explain Circular and Orbital Motion Let's start by looking at circular motion with constant speed. Can there be acceleration in this problem? Yes, velocity includes speed and
Ampere; A (after A.M. Ampere, 1775-1836) The basic SI unit of electric current, described as the current that, while going through two infinitely-long parallel conductors of ne
Define, with the help of diagram, the principle and working of an a.c. Generator. Write the expression for the e.m.f. generated in the coil in terms of its speed of rotation
A lead bullet moves horizontally with a velocity of 130 ms-1 and embedded into a cement wall after collision. If the specific heat capacity of lead = 130 JKg-1°C-1 and all heat pro
(i) The procedure of ejection of electrons from a metal surface by the application of heat is known as thermionic emission and emitted electrons are known as thermions and current
A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in the accordance with ohm’s law.
Motion of an object in a plane is called two dimensional (2-D) motions. For 2-D motion acceleration or velocity can be explained by two elements in any two mutually perpendicular d
A 2kg piece of copper at 200 o C is taken out of a furnace and is allowed to cool in air with an ambient temperature of 25 o C. Calculate the entropy change in the universe as a
