  • I just proved Einstein wrong where's my nobel prize?

    Something with matter gains mass as it gains energy, so therefore matter and energy are both mass. If energy is mass then how does energy equal mass times c^2?

  • Does this theory make sense?

    My dad told me his theory of another planet just like earth in our solar system. So he believes that there is another planet on our orbit exactly on the other side of the sun that's just like earth. He says that they move at the exact same speed in the same orbit around the sun, never to meet eachother. I... show more
    My dad told me his theory of another planet just like earth in our solar system. So he believes that there is another planet on our orbit exactly on the other side of the sun that's just like earth. He says that they move at the exact same speed in the same orbit around the sun, never to meet eachother. I believe it would make sense, because we have sent out small spacecrarts to explore space, but we have never sent one to follow our orbit. If we sent one the opposite way that the earth moves, we could see if his theory could be true. It may or may not be true, but I believe it could be true, but we don't have proof

  • Can you solve this quadratic equation?

    Best answer: the equation 2x² + 5x + 3 = 0 can be solved:

    2x^2 + 2x + 3x + 3 = 0

    2x(x + 1) + 3(x + 1) = 0

    (2x + 3)(x + 1) = 0

    x = -3/2, x = -1
    Best answer: the equation 2x² + 5x + 3 = 0 can be solved:

    2x^2 + 2x + 3x + 3 = 0

    2x(x + 1) + 3(x + 1) = 0

    (2x + 3)(x + 1) = 0

    Its seems like these people really want us to be prepared for the worst and its very understandable but when it comes to stuff like this I was reading up about a very big one that occurred way back in the late 1850's 1859 to be exact it was apparently known as the Carrington Event accordingly it a very big solar storm and known to be one the biggest ones that occurred way back then from what it sounds like this type of storm was so big thats kind of rare that we see storms like the Carrington event but from what they said about it if we had one like that one in todays world of course it'd be catastrophic cause think about all the stuff it would knock out and possibly for a long time now even though they say another is coming but I think its going be as big as that one from many years ago but still big a one but heres the thing for me how do we know if this next one would hit us or just pass us by and we'd just have to wait & see will find out 04/23 or 04/24 cause thats when they expect it to reach us also I haven't noticed the effects of solar flares all that much lately heck it might not even be nothing to worry about I think nasa and those guys bullsh*t us about stuff like this a lot I say its not gonna be that big of deal if this does happen because if we go through anyblackouts from this when it comes it would only be about a couple days or so but anyways I would like to get your opinions on this what do you think will happen and are any you worried about it?

  • A plate carries a charge of -3.1 nC and a rod carries a charge of +8.4 nC?

    Best answer: Let’s determine the difference of these two charges. ∆ Q = +8.4 – -3.1 = 11.5 11.5 ÷ 2 = 5.75 nC This is the amount of charge that must be transferred. -3.1 + 5.75 = 2.65 nC 8.4 – 5.75 = 2.65 nC This is charge of both objects. For both objects to have the same charge, a charge of 5.75 nano coulomb must be... show more
    Best answer: Let’s determine the difference of these two charges.
    ∆ Q = +8.4 – -3.1 = 11.5
    11.5 ÷ 2 = 5.75 nC
    This is the amount of charge that must be transferred.

    -3.1 + 5.75 = 2.65 nC
    8.4 – 5.75 = 2.65 nC
    This is charge of both objects.

    For both objects to have the same charge, a charge of 5.75 nano coulomb must be transferred.

    q = 5.75 * 10^-9 C

    The charge of one electron is 1.6 * 10^-19 C. Let n be the number of electrons that must be transferred.

    n * 1.6 * 10^-19 = 5.75 * 10^-9
    n = 5.75 * 10^-9 ÷ 1.6 * 10^-19 = 3.59375 * 10^10 electrons
