So how much mass must be converted to release 1 million kilowatt hours of energy? we'll be using the equation e equals mc squared.
00:17
So 1 million kilowatt hours, that is, e is equal to 10 to 6 kilowatt hours.
00:28
We want to convert this into joules.
00:30
So multiply by 1 ,000, then multiply by 60 to get minutes, then multiply by 60 to get seconds.
00:41
We get that the energy is going to be 3 .6 times 10 to the 12 joules.
00:55
C is equal to the speed of light, 3 times 10 to the 8th.
01:00
So we're going to square that.
01:03
C squared is equal to 9 times 10 to the 16 meters per second.
01:11
Now that we have everything, we simply have to isolate mass...
