Aradioisotope has a neutron/proton ratio which is too low. which of the following processes is least likely to occur for such a nucleus? i. alpha emission ii. beta emission iii. electron capture iv. positron emission v. all the above are equally likely to occur

I'm not sure what your asking buddy.. but i know that you can weld two peices of steel by pure force and pressure.

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.
