Which of the following is true? when a nucleus is separated into its constituent protons and neutrons, the sum of the masses of the individual protons and neutrons is less than the mass of the stable nucleus. when a nucleus is separated into its constituent protons and neutrons, the sum of the masses of the individual protons and neutrons is greater than the mass of the stable nucleus.

the sum of the masses of the individual protons and neutrons is less than the mass of the stable Nucleus

Explanation:

Nuclei fission involved bonds breaking with the loss of quantity of Energy by the protons and Neutrons

Remember : e=mc2

Therefore, this breakage of bonds result in loss in masses of p and n.

However, in intact Nucleus the energies of the p and n are trapped in the intact bonds holding them together therefore heavier masses than when broken down.

good thing- during decomposition the organic molecules in organic matter are broken down into simpler organic molecules that require further decomposition or into mineralised nutrients

bad thing- it can be harmful in crop productivity

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
