By designing mass spectrometers that can determine m/z values accurately to four decimal places, it is possible to distinguish different formulas having the same nominal mass. The table on the right illustrates this important feature, and a double-focusing high-resolution mass spectrometer easily distinguishes ions having these compositions.

What we have to find?

Answer 2

Answer:

u=0 v2=u+2as

Explanation:

that means v=1/2gh
