We can understand why 235u is readily fissionable, and 238u is not, by usingthe following calculation.
(a) find the energy difference between 235u + nand 236u. we can regard this as the "excitation energy" of 236u.
(b) repeat (a) for 238u + nand 239u.(c) (2 pts) comparing your results for (a) and (b), explain why 235u will fission with very low energy neutrons, while 238u requires fast neutrons of 1 to 2mev of energy to fission.

You can still be friends with each other. you don't have to date since he likes someone else. just stick to being friends for now

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
