The emission of a beta particle has the effect of : C. No change in mass
basically, beta particle has a very very little mass compared to the proton and neutrons, so little to the point that it never considered as a change in mass. But it does decreases the charge of atom
hope this helps
Argon is the third most common gas found in the air we breathe. The air we breathe has approximately 78% nitrogen and 21 % oxygen. The third more abundant gas in the air we breathe is Argon. It is available in a very small quantity in the air that we breathe.
The percentage of the gas argon is about 0.9% in the air
that we breathe. There are several other gases also present in the air that we
breathe, but they are found mostly in negligible amounts.
Explanation:
workdone = force x distance
force = mass x acceleration
30 x 10 = 300N
300N x 1m
workdone= 300J
Answer:
Final pressure = 362.7 Pa
Explanation:
Given that,
Initial volume, V₁ = 930 ml
Initial pressure P₁ = 156 Pa
Final volume, V₂ = 400 mL
We need to find the final pressure. We know that the relation between volume and pressure is inverse i.e.
So, the final pressure is equal to 362.7 Pa.
