Using the liquid drop model, plot on the same graph, as a function of a, in units of mev/nucleon (a) the bulk volume binding energy per nucleon, (b) the negative of the surface binding energy per nucleon, (c ) the negative of the asymmetry contribution per nucleon, (d) the negative of the columbic contributing per nucleon, and (e) the total binding energy per nucleon ignoring the pairing terms. for a given a value, use z determined from eq. (3.18) for the most stable member of the isobar z(a)2

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."

answer: the correct answer is 1.

explanation: there are various process in which a radioactive nuclei decays:

1) alpha decay: in this process, a heavier nuclei decays into lighter nuclei by releasing alpha particle. the mass number is reduced by 4 units.

2) electron capture: in this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. simply, a proton and an electron combines together to form a neutron. mass number does not change in this process.

3) gamma ray emission: it is a decay process in which an unstable nuclei gives excess energy by a spontaneous electromagnetic process. this decay releases . this process does not change the mass number.

4) positron emission: it is a type of decay process, in which a proton gets converted to neutron and an electron neutrino. this is also known as -decay. in this the mass number remains same.

from the above information, we see that only alpha-decay is producing a change in the mass number of the nucleus.
