this question. First, find out how much energy is required to operate your light bulb for one hour. Now we're given the poverty like always 100 once, so it uses up 100 juice for a second. So the energy required for one hour She closed two D, taking the power multiplied by total number of seconds in one hour. And there is ST on 600. But you don't 600 seconds power. So why should get use? Water it down. Tree Don't 600. He gets 3.6. I'm set about five juice. No, to find in a more fission reactions or events that require documented energy for each fission. Make sure he's 208 MTV. Now let us come better into juice. What? By by 1.6 times 10 part minus 13 e juice. Put MVV Sorry, You get three points Tree times 10 apartments Levin juice. So the number of fissures there you take Tripoli 6 to 10 45 developed by she points You treat Paul minutes 11 we get one points you eat. Send power 60 to the scene of the official reactions. Quiet two polity like about for an hour
