In a nuclear experiment a proton with kinetic energy 1.0 mev moves in a circular path in a uniform magnetic field. what energy must (
a. an alpha particle (q = +2e, m = 4.0 u) and (
b. a deuteron (q = +e, m = 2.0 u) have if they are to circulate in the same circular path?

A. an alpha particle (q = +2e, m = 4.0 u) and 

Ur e n d is not real

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
