Each shot of the laser gun most favored by Rosa the Closer, the intrepid vigilante of the lawless 22nd century, is powered by the discharge of a 1.89 F capacitor charged to 59.9 kV . Rosa rightly reckons that she can enhance the effect of each laser pulse by increasing the electric potential energy of the charged capacitor. She could do this by replacing the capacitor's filling, whose dielectric constant is 435 , with one possessing a dielectric constant of 923 . Find the electric potential energy of the original capacitor when it is charged.

Energy stored in original capacitor is

Explanation:

We have given capacitance

Capacitor is charged by

We to find energy stored in the capacitor when it is charged

Energy stored in original capacitor is equal to

So energy stored in original capacitor is

the part of the wave he is travelling on is the crest

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
