Aneutron and a proton combine to form a nucleus. how does the mass of the nucleus compare with the sum of the masses of its individual particles?

a. the nucleus has less mass, because matter is converted into binding energy.

b. the nucleus has more mass, because matter is converted into binding energy.

c. the nucleus has less mass, because binding energy is converted into matter.

d. the nucleus has more mass, because binding energy is converted into matter.

Now that we have a feel for the state of the circuit in its steady state, let us obtain the expression for the current in the circuit as a function of time. note that we can use the loop rule (going around counterclockwise): e−vr−vl=0. note as well that vr=ir and vl=ldidt. using these equations, we can get, after some rearranging of the variables and making the subsitution x=er−i, dxx=−rldt. integrating both sides of this equation yields x=x0e−rt/l. use this last expression to obtain an expression for i(t). remember that x=er−i and that i0=i(0)=0. express your answer in terms of e, r, and l. you may or may not need all these variables. use the notation exp(x) for ex.
