It tells us the number of protons that are present in the nucleus, the positively charged region of that atom.
Answer:
3.834 m/s
Explanation:
h = 0.750 m
vx = 5 m/s
Let the initial vertical velocity is vy.
Final vertical velocity is zero
use third equation of motion along y axis
v^2 = vy^2 - 2 x g x h
0 = vy^2 - 2 x 9.8 x 0.75
vy^2 = 14.7
vy = 3.834 m/s
Increasing the pressure of gas is like exactly the same as increasing its concentration. If you have a given mass of gas, the way you increase its pressure is to squeeze it into a smaller volume.
Hope this helps!
