Compton effect (A.H. Compton; 1923)
An effect which demonstrates that photons (the quantum of electromagnetic radiation) contains momentum. At a stationary particle, a photon fired such as an electron, will impart momentum to the electron and, as its energy has been reduced, will experience a corresponding falling in frequency.
A 100 hp car engine operates ata bout 15 percent efficiency. Assume the engine's water temperature of 85°C is it scold-temperature (exhaust) reservoir and 500°C is its thermal "int

Rydberg constant (Rydberg): A constant that governs the relationship of the spectral line features of an atom by the Rydberg formula. For hydrogen, it is about 1.097 x 10 7 m
theory of wedge constraint

WHAT IS MACHINE
The phase of weightlessness may be observed in the following situations: (i) When objects fall freely under gravity : For example, a lift goes down freely, or an airship showing
