Define Kirkwood gaps
Kirkwood gaps (Kirkwood): The gaps in the asteroid belt, caused by the resonance effects from Jupiter. Similar gaps are also exists in Saturn's rings, due to the resonance effects of the shepherd moons.
What do you mean by the term Newton meter? Explain briefly?
Lenz's law (H.F. Lenz; 1835): The induced electric current always flows in such a direction that it resists the change generating it.
Planck constant: h: The basic constant equivalent to the ratio of the energy of a quantum of energy to its frequency. This is the quantum of action. This has the value 6.626 196 x 10-34 J s.
Roche limit: The position about a massive body where the tidal forces due to the gravity of the primary equivalent or exceed the surface gravity of a specified satellite. Within the Roche limit, such a satellite will be interrupted by tides.
What is main difference between secondary electron image and the back scattered electron image? State briefly.
Define the term engineering in brief.
Write a short note on diffuse reflection?
For the magnetically coupled circuit in Figure a, calculate I1 and I2. If the dotted terminals in are changed so that the circuit now becomes that in Figure b, re-calculate I1 and I2.
When one coil of a magnetically coupled pair has a current of 5.0A, the resulting fluxes Φ11 and Φ21 are 0.2mWb and 0.4mWb, respectively. If the turns are N1 = 500 and N2 = 1500, find L1, L2, M and the coeffici
Planck radiation law: The law which explained blackbody radiation better than its precursor, therefore resolving the ultraviolet catastrophe. This is based on the supposition that electromagnetic radiation is quantized.
