Nuclei Test - 2...

When four hydrogen nuclei fuse together to form a helium nucleus, then in this process

What is the mass of one atom of $$C-12$$ in grams?

Isotopes are the atoms of the same element which contain equal number of

The kinetic energy of $$\alpha$$-particles at a distance $$5  \times 10^{-14}$$m from the nucleus will be(in Joules)

The energy released per fission of Uranium is 200 MeV. Determine the number of fission per second required to generate 2MW power.

Write the following steps of the liquid drop model in sequential order to show the various stages of a nuclear fission reaction.
(a) During the bombardment of a nucleus by neutrons, a neutron could be absorbed by the drop like the nucleus.
(b) A heavy nucleus is treated as the drop of a liquid with the positive charge uniformly distributed.
(c) This leads to the disturbance of the internal forces and sets up oscillations.
(d) From this stage the repulsive forces take over causing the fission of the nucleus.
(e) These oscillations lead to the development of a thick neck forming two parts, giving the nucleus and elongated shape.

One a.m.u. or one 'u' is equal to :

The sun's energy is due to

The modern atomic mass unit is based on the mass of :

The average $$\ KE $$ of molecules in a gas at temperature $$\ T $$ is $$\displaystyle \frac {3}{2}kT $$. Find the temperature at which the average KE of molecules equal to binding energy of its atoms.
