Hawking temperature:
The temperature of a black hole caused through the emission of Hawking radiation. For a black hole along with mass m, it is following
T = (hbar c3)/(8 pi G k m).
As blackbody power emission is proportional to the area of the hole & the fourth power of its thermodynamic temperature, the emitted power scales like m-2 i.e. as the inverse square of the mass.
A cylinder having 1.00 g of water at the boiling point is heated until all the water turns into steam. The expanding steam pushes a piston 0.365 m. There is a 215-N frictio

When an electron makes transition from higher energy level having energy E2(n2) to a lower energy level having energy E1 (n1) then a photon of frequency v is emitted.
