Write down a brief note on the classification of Alloys?
Expert
Alloys can be categorized by the number of their components. The alloy with two components is termed as binary alloy; one with three is termed as ternary alloy and so on. Alloys can be further categorized as either substitution or interstitial alloys, depending on their process of formation. In substitution alloys, the atoms of components are around of similar size and the different atoms are simply replaced for one another in the crystal structure. An illustration of a binary substitution alloy is brass, which is made up of copper and zinc. Interstitial alloys take place whenever the atoms of one component are substantially smaller than the other and the smaller atoms fit to the spaces (or interstices) among the bigger atoms.
Explain Thermodynamic laws and also First law, Second law, third law and zeroth law of thermodynamics? Thermodynamic laws: Q : Define Watt or SI unit of power Watt: W Watt: W (after J. Watt, 1736-1819): The derived SI unit of power, stated as a power of 1 J acting over the period of 1 s; it therefore has the units of J/s.

Explain how is energy transformed in the windmills?
The velocity of a body was observed to be constant throughout five minutes of its motion. Determine its acceleration during this interval?
No-hair conjecture (1960s): The conjecture (confirmed in the 1970s and 1980s) in general relativity that a black hole has merely three salient external characteristics: angular momentum, mass, and electric charge. All the other proper
Tachyon paradox: The argument explaining that tachyons (should they subsist, of course) can’t carry an electric charge. For an imaginary-massed particle travelling faster than c, less energy the tachyon has, the faster it travels, till at zero e
Cosmological redshift: The effect where light emanates from a distant source appears redshifted since of the expansion of the space time itself.
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.
The voltage v mV in a circuit is given by: v = 20 sin (200 Πt - 0.7854) where t is the time in seconds (a) State the amplitude, frequency, period and phase angle of v.(b) Determine the initial voltage.(c) Determin
