The electric potential energy is $1\cdot 10^{-7} J$

Explanation:

The electric potential energy stored in a capacitor is given by the equation

$PE=Q \Delta V$

where

Q is the charge stored in the capacitor

$\Delta V$ is the potential difference between the plates

For the capacitor in this problem, we have

$Q=4.0\cdot 10^{-10}C$ is the charge

$\Delta V=250.0 V$ is the potential difference

Substituting, we find the potential energy:

$PE=(4.0\cdot 10^{-10})(250.0)=1\cdot 10^{-7} J$

A force of 3600 N is exerted on a piston that has an area of 0.030 m2. What force is exerted on a second piston that has an area

Airida [17]

For Pascal's law, the pressure is transmitted with equal intensity to every part of the fluid:
$p_1 = p_2$
which becomes
$\frac{F_1}{A_1}= \frac{F_2}{A_2}$
where
$F_1=3600 N$ is the force on the first piston
$A_1=0.030 m^2$ is the area of the first piston
$F_2$ is the force on the second piston
$A_2=0.015 m^2$ is the area of the second piston

If we rearrange the equation and we use these data, we can find the intensity of the force on the second piston:
$F_2=F_1 \frac{A_2}{A_1}=(3600 N) \frac{0.015 m^2}{0.030 m^2}= 1800 N$
