Assume the radius of a neutron to be approximately 1.0×10−13 cm, and calculate the density of a neutron. [hint: for a sphere v=(4/3)πr3.]

The density of the neutron,

Here, m is the mass and V is the volume.

Now to calculate the volume of a neutron, we use the formula

Here r is the radius of the neutron and its value of

So,

We know the mass of neutron,

Thus,  

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."

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
