    What is Taking Up Space on My Hard Drive?

    deleting files won't make it run any faster, you can try disk defrag

    Undergrad Half Life of radioactive element

    no youre wrong, half-life decay is like a log function, so doubling the time won't mean it would decay

    High School Does a full 3TB hard drive weigh more than an empty one?

    as far as I know no chemical reactions occur in this process like the book, a hard drive merely rearranges electron to create storage spaces etc. SO no, it wouldn't weigh any more than a brand new one.

    Graduate Why artificial gravity is not possible?

    It IS possible, you have to rotate the ship about its horizontal axis to create a force that holds the astronauts to the circular hull/floor of the ship

    The Earth is heated by gravitational forces I think, not magnetic
