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.

Answer:
'
Explanation:
It is given that,
Mass of the plunger, 
Mass of the bullet, 
Initially both plunger and the bullet are at rest, 
Final speed of the bullet, 
Let 
is the final speed of the plunger. Using the conservation of momentum to find it. The equation is as follows :
Since,
So, the recoil velocity of the plunger is 8.19 m/s. Hence, this is the required solution.
Answer:
Potential energy turn to kinetic energy
Explanation:
Answer:
40%
Explanation:
Student -> Pump = 100j
Pump -> Tire = 40j
Between the two, 60j of energy were lost.
Efficiency = 40/100 = 40%
