what different is between photons?
Answer; the difference between photons depends to their frequency, and frequency depends to the number of CPH in structure of photon.
Thus, the number CPH in red photon is less that the number of CPH in blue photon.
Total height of the gymnast just before falling back down is=(2+.3)=2.3m Energy gained at that point = m*g*h(m=mass, g=gravitational force, h=height) =55*9.8*2.3=1239.7 J

What do you mean by thermal neutron? What is its importance? What do you mean by annihilation of matter? Given an example
Brownian motion (R. Brown; 1827) It is the continuous random motion of solid microscopic particles while suspended in a fluid medium because of the consequence of ongoing bomb
An x-ray photon collides with a free electron, and the photon is scattered. During this collision there is conservation of: a) momentum but not energy b) neither moment
Energy: The term energy may be defined as the capacity for doing work. There are two forms of energy: potential energy and kinetic energy. POTENTIAL ENERGY Potential e
