Joules is the unit of measurement for "work," right?
And work requires energy, so I guess
Energy = 1000(c)^2?
Sorry, not in Physics. Only taking Bio P-AP since it is my freshmen year, but I know what the variables in the equation is. |

| Gah, 7th and 8th grade Science only goes to the freaking Joules. My Biology Teacher goes way in depth though, so I wish I had her for my 7th and 8th grade years as well. Man, I love teachers that go way beyond the book, since I learn something actually "useful" in life that sets me apart from the "regulars" and into the category of "advanced." |

| Ok the anwser is: 100'000'000'000'000'000 joules (100 trillion) this could lift up a middle sized lake one kilometer up! You can also calculate this with e=mc2 |

| Because they're composed of gas that emits the color blue. Simple as that. Also, Neptune (I think it's Neptune) is tilted the wrong way. |

What do you mean with neptune is titled wrong? Anyway your basicly right. Neptunes outher atmosphere is made out of hydrogen, helium and methane (and a few other gases) and the methane doesent reflect the red glowing of the sun. It just reflects the blue light. (sorry about the bad english, im swiss) |
