(a) Explain the terms: 'magnetic field strength', 'magnetic flux density' and 'permeability' of a magnetic material. Write their SI units.
A current carrying conductor is placed at an angle of 30° to a uniform Magnetic field of strength 2×10³ T. The length of the conductor inside the Magnetic field is 2 m and the current flowing through it is 1.6 A. Calculate the Magnitude of the force experienced by it.
(b) Distinguish among 'nuclear fission' and 'nuclear fusion'. Which one of them is used for release of energy in a nuclear reactor? Name one fuel used in a nuclearreactor.
(c) With the help of a circuit diagram, explain the working of a P-N-P transistor.
Refracting telescopes, if uncorrected, suffer from chromatic aberration. Chromatic aberration occurs because: a) red light is focused more strongly than blue light b)
how temperature increases w.r.t. voltage and current for same wire
Q. Why there is no horizontal acceleration during projectile motion? Ans: The gravitational force (F)acting on the particle during its flight has only vertical component i.e. F(co
To determine the acceleration due to gravity using a simple pendulum. Apparatus: Pendulum, meter scale, stand, stop watch, vernier callipers. Procedure: 1. The diameter of the bob
