The mass fraction of the hydrogen atom is 0.9995 u.
<h3>Calculation:</h3>
We know that mass fraction can be determines as,
Mass fraction = Mass of proton/mass of H atom
Given,
Mass of proton = 1.007276 u
Mass of H atom = 1.007825 u
Put the values in the formula,
Mass fraction = Mass of proton/mass of H atom
Mass fraction = 1.007276/1.007825
= 0.9995 u
Hence, the mass fraction of the hydrogen atom is 0.9995 u.

Explanation:
Number 29
= 10 N (from rocket) + 10 N (from wheels) - 7 N (from parachute 'cause force in other direction)
= 20 N - 7 N
= 13 N ✔
Number 30
= 100 N - 85 N
= 15 N to the left ✔
