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.
When current is passed by a junction of two dissimilar solids, the temperature is either evolved or absorbed at the node. This effect is known as Peltier effect
When atoms (or) group of atoms are added, to form more saturated compound it is known as addition reaction.
Davisson and Germer scattered electrons from a crystal of nickel. The scattered electrons formed a strong diffraction pattern. What important conclusion was drawn from this experi
two insulated charged copper spheres A and B of identical size have charge q and -3q respectably .when they are brought in contact with each other and then separated,what are the n
In nuclear fusion two or more than two lighter nuclei join to form a single heavy nucleus. The volume of one molecule so formed is less than the sum of the masses of parent nuclei.
Determine the zero-point energy of a harmonic oscillator havingof a particle of mass 2.33 x 10 -26 kg and force constant 155 N m -1 .
Differentiate between displacement current and conduction current.
If we have to strain a ferromagnetic crystal along certain direction, we would change the inter atomic spacing not only along this direction but also in other direction. And hence
Hence refractive index µ can be determine by measuring the diameter of Newton's rings first with air and then with the liquid for same value of m.
Determine the ratio of the frequencies of harmonics in an air column of same length in a) a closed pipe and b) an open pipe
