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.
Moment, Centre of mass and Centroid Moment of force is tendency of the force to twist or rotate an object. A measure of the body's resistance to the angular acceleration, which
Explain about the single mode fibres in intermodal dispersion. Into single mode fibers, the core size of the fibre is decreased to 3 to 9µm so that this supports simply axial m
what is needed to make assignment on electromagnetism?
Applied Force (Fapp) : an applied force is a force that is useful to an object by a person or another object. If a person is approaching a desk across the room, there is applied fo
Explain the Spinning Problems The Law of Conservation of Angular momentum states that if there is no net applied torque on a body then angular momentum is conserved. This is si
Explain electric flux. Write its S.I. units. A spherical rubber balloon carries a charge that is uniformly distributed over its surface. As the balloon is blown up and enhances in
How many dimension follow a atomic particle?
Q. What is a frame of reference? A system of co-ordinate axes which describe the position of a particle in two or three dimensional space is called a frame of reference.
(i) On the average, particles are separated by a distance of the order of 10-10 m and exert a force of attraction of the order of 10-11 N on each other. (ii) The force of atta
SECOND DEFINITION OF IMPULSE: It can be described as, "The change in momentum produced by the force of impulse".
