Rutherford's alpha-scattering experiment recognized that the mass of atom is concentrated with small positively charged region at the centre which is known as 'nucleus'.
Nuclei are made up of neutron and proton. The quantity of protons in a nucleus (known the atomic number or proton number) is shown by the symbol Z. The number of neutrons (neutron number) is represented by N. The total quantity of neutrons and protons in a nucleus is known it's mass number A so A = Z + N.
Neutrons and proton, when explained collectively are known as nucleons.
Nucleus have two types of particles : Protons and neutrons
Why are some flashlights brighter than others?

1). A ring of outer diameter 80 cm is made from square of cross -section steel bar size(8 *8 cm) . If relative permeability 1200 for steel . calculate the current needed to produce
Demonstrate the typical ultrasonic flaw detector in its reflection modes? A typical ultrasonic flaw detector into its reflection modes is as demonstrated below: Assume
A copper rod which is 1 centimetre in diameter carries a current of 5 amps. The current is distributed uniformly over the rod. The magnetic field half way among the axis o
Construction and working of michelson interferometer,.how will you use it to measure the wavelength of a monochromatic light.
Because force=dp/dt and force=0 in first law of motion => dp/dt=0 => p=const. or linear momentum is conserved.
A bar has a 20N weight at one end. You have a weight of 15N to hang somewhere on the bar so that the bar is in equilibrium. Where would you hang the 15 N weight on each of these ba
For the system shown below the gain, G, of block A is variable and can be set as low as 100 and as high as 500. The only problem with block A is that its gain fluctuates with high
