Answer:
900 W.
Explanation:
Given that
Electric heater 1500 W
We know that power P given as
P= V I
So the total power of 120 V and 20 A circuit
P = 120 x 20
P= 2400 W
So the power new load P'
P'= Total system power(P)- Electric heater load
P ' = 2400 - 1500
P'= 900 W
So the answer is 900 W.

Explanation:
1) the helium in the suns atmosphere from the original helium and any helium the sun has produced from the nuclear fusion of hydrogen.
2) the helium present in Jupiter's atmosphere came from the helium in the matter that produced our solar system.
3) the helium found in the suns core comes only from the nuclear fusion of hydrogen
