In Rutherford's experiment including the deflection of alpha particles by atomic nuclei, the fact that some of the alpha particles bombarding the thin gold foil were back-scattered, led to.
It was concluded that
Ans- Most of the mass of a gold atom is in its nucleus
Describe the theory of black body. Black body At an exact temperature the black body would produce the maximum amount of energy probable for temperature. This would emit at

Sclera: It is an outer most, thick, impermeable to light. It is more convex and it's front part is transparent is known as Cornea.
A student finds that a particle whose life is micro-sec (µ- sec) moves with a velocity of 2.7 x 108 m/sec. i) What will be its lifetime as measured by another observer in the labor
A monochromatic parallel beam of light is incident on a single slit. Graphically show the intensity distribution among the secondary maxima and principle maxima in diffracted beam.
After the parallel algorithm has been written as well as executed performance of both algorithms is one of other main concerns. In order to examine performance of algorithms there
Given that dH for the reaction is -92.2 kJ mol-1, which is larger, the total bond dissociation energy of the reactants or the total bond dissociation energy of the products?
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
Major steps for analyzing forces in uniform circular motion: Let consider one axis along the radius of circle (i.e. in direction of acceleration) and other axis perpendicular to th
Translational : If a body goes such that its orientation does not change with respect to time then body is said to move in translational motion. ROTATION : If an object is rota
