Why are gamma rays not affected by a magnet as they pass over it? gamma rays are composed of only energy. gamma rays do not have enough mass to be affected. gamma rays do not have the right electrical charge to be affected. gamma rays move too fast for anything to affect their pathway.

Apeak with a retention time of 407 s has a width at half-height (w1/2) of 7.6 s. a neighboring peak is eluted 17 s later with a w1/2 of 9.4 s. a compound that is known not to be retained was eluted in 2.5 s. the peaks are not baseline resolved. how many theoretical plates would be needed to achieve a resolution of 1.5?
