Given two electrons with charge of 1.5x10^-10 m
The electostatic force between them is determined by this formula:
F = kq1q2/r^2
where
k = 9x10^9
q1 = q2 = 1.5x10^-10
r = 2.82x10^-15
F = 9x10^9 * (1.5x10^-10)^2 / 2.82x10^-15
= 71808.51
Answer: 1.87 atm
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 2.50 atm
= final pressure of gas = ?
= initial volume of gas = 26.4 ml
= final volume of gas = 36.2 ml
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The new pressure is 1.87 atm by using combined gas law.
The work formula is W=Fx and and so for the first box it would be W= (4)•(0.5)= 2 J. On the other hand for the second box it would we W= (1)•(4)= 4 J. Therefore the second box is more work
