I am not sure on the rest but the answer to question 4 is volts. sorry i couldn’t be of more help!
Answer:
1000 kg
Explanation:
We know the formula for finding out weight is W=mg
W= 10,000 N
M=?
g=10 N/KG
W=mg
10,000=10m
m=1000kg
Answer:
C. changing nuclear energy to radiant energy
Explanation:
Nuclear energy takes atoms in their potential state, split them (fission) or fuse them (fusion) creating chain reactions of radiant energy. Most nuclear electrical power plants use fission, radiant energy heats water making steam to spin turbines.
Or think of the atom bomb. Definitely potential energy until the fuse starts detonation and chain reactions. The radiant kinetic energy and shock waves were horrendous.
