(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.
These are non-metallic compounds consisting of ferric oxide and one or two bivalent metal oxides such as NiO, MnO. These have resistivity of the order of 10 9 O cm, which reduces e
Isn't there any relation to calculate the dipole moment from the electronegativities of the participating atoms? Solution) formulae:- 16(X A -X B )+3.5(X A -X B ) 2
At certain sharply explained wavelengths, the power of X-rays is very large as marked K alpha, K beta .... As shown in figure. These X-rays are called as property of X-rays. At oth
What is Ancient view Ancient view: objects tend to stay if they are in motion; force is needed to keep something moving. This was a natural thing to believe in because we see
An ideal Rankine cycle uses water as a working fluid, which circulates at a rate of 80 kg/s. The boiler pressure is 6 Mpa, and the condenser pressure is 10 kpa. The water enters th
Weiss constant: A characteristic constant based on the material, utilized in calculating the susceptibility of paramagnetic materials.
