For the nuclear reaction:
The blank space can be filled by:
1.
2.
3.
4.
Nuclear – fission is best explained by:
1. Liquid droplet theory
2. Yukawa - meson theory
3. Independent particle model of the nucleus
4. Proton-proton cycle
The energy released in nuclear fission is due to:
1. | some mass is converted into energy |
2. | the total binding energy of fragments is more than the B.E. of the parental element |
3. | total B.E. of fragments is less than the B.E. of parental element |
4. | total B.E. of fragments is equal to the B.E. of parental element |
Which of the following are suitable for the fusion process?
1. | light nuclei |
2. | heavy nuclei |
3. | the element must be lying in the middle of the periodic table |
4. | middle elements which are lying on the binding energy curve |
Solar energy is mainly caused due to:
1. | burning of hydrogen in the oxygen |
2. | fission of uranium present in the sun |
3. | fusion of protons during synthesis of heavier elements |
4. | gravitational contraction |
In any fission process the ratio
1. Greater than 1
2. Depends on the mass of the parent nucleus
3. Equal to 1
4. Less than 1
Fission of nuclei is possible because the binding energy per nucleon in them:
1. | decreases with the mass number at low mass numbers |
2. | increases with the mass number at low mass numbers |
3. | decreases with the mass number at high mass numbers |
4. | increases with the mass number at high mass numbers |
