The electric potential energy is 
Explanation:
The electric potential energy stored in a capacitor is given by the equation
where
Q is the charge stored in the capacitor
is the potential difference between the plates
For the capacitor in this problem, we have
is the charge
is the potential difference
Substituting, we find the potential energy:

Answer:
1.17 x 10^2 L
Explanation:
We can find the volume of the gas by using the ideal gas law:
where we have:
is the pressure
V is the volume
n = 4.8 mol is the number of moles
R = 0.0821 L · atm/mol · K is the ideal gas constant
is the temperature
Solving the equation for V, we find the volume
Answer:
2160.26 N.
Explanation:
From the question,
The total energy of the woman = work done by the water.
mg(h+d) = F'×d.......................... Equation 1
m = mass of the the woman, g= acceleration due to gravity, h = height of the platform, d = depth of water reached by the woman, F'= Resistance force exerted on her by the water.
make F' the subject of the equation
F' = mg(h+d)/d............................ Equation 2
Given: m = 65.0 kg, g = 9.8 m/s², h = 11 m, d = 4.6 m.
Substitute into equation 2
F' = 65(9.8)(11+4.6)/4.6
F' = 9937.2/4.6
F' = 2160.26 N.
D............................
in this since your volume remains at a constant you'll need to use Gay-Lussacs law, p1/t1=p2/t2.
your temp should be converted in kelvin
variables:
p1=3.0×10^6 n/m^2
t1= 270k
just add 273 to your celcius
p2= ? your solving for this
t2= 315k
then you set up the equation
(3.0×10^6)/270= (x)(315)
you then cross multiply
(3.0×10^6)315=270x
distribute the 315 to the pressure.
9.45×10^8=270x then you divide 270 o both sides to get
answer
3.5×10^6 n/m^2
