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 1.27 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 421, with one possessing a dielectric constant of 907.find the electric potential energy of the original capacitor when it is charged.

U = 1794.005 × 10⁶ J

Explanation:

Data provided;

Capacitance of the original capacitor, C = 1.27 F

Potential difference applied to the original capacitor, V = 59.9 kV

= 59.9 × 10³ V

Now,

The Potential energy (U) for the capacitor is calculated as:

Potential energy of the original capacitor, U =  × C × V²

on substituting the respective values, we get

U =  × 1.27 × ( 59.9 × 10³ )²

or

U = 1794.005 × 10⁶ J

there are no correct statementd on the list of choices you provided.

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
