A nuclear power plant produces power with a current of 15.0 kA. A transformer with 500 windings in the primary circuit and 1700 windings in the secondary circuit is used to step up the potential difference to 198 kV. Calculate the power the nuclear plant produce. Assume no energy is lost in the transformers.

873 MW

Explanation:

Find the voltage in the primary circuit.

Vp / Vs = Np / Ns

Vp / 198 kV = 500 / 1700

Vp = 58.2 kV

Calculate the power.

P = VI

P = (58.2 kV) (15.0 kA)

P = 873 MW

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.

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.
