(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.
HYSTERESIS LOOP: A ferromagnetic material retains some magnetism after the magnetising force is removed. The BH curve (O to Q) will therefore only be followed once, on initial
The initial conditions for an air-standard Otto cycle operating with a compression ratio of 8:1 are 95 kPa and 17 o C. At the beginning of the compression stroke, the cylinder vol

The molar heat capacity of a gas at constant pressure is 18.7 J mol -1 K -1 . What is the heat capacity of 9.4 moles of this gas at constant volume ?
The simple equation E = mc² is not usually applicable to all these types of mass and energy, except in the special case that the total additive momentum is zero for the system unde
Suppose you sound a 1056-Hz tuning fork at the same time you strike a note on the piano and hear 2 beats/second. You tighten the piano string very slightly and now hear 3 beats/s
