  • Is it possible for time travel to exist with the right technology?

    I've heard traveling into the future is possible but traveling back in time is really hard. One of my friends actually time traveled before so he asked me if I wanted to come next time he goes I'm a bit scared though.

  • A rubber ball is dropped from the top of a hole. Exactly 1.5 seconds​ later, it's heard hitting the bottom. How deep is the hole​?

    Best answer: The speed of sound in air is 343 m/s. During the first part of 1.5 seconds, the ball falls from the top to the bottom of the hole. During the second part of 1.5 second part of the 1.5 seconds, the sound rises from the bottom to the top of hole. Let t be the time the ball is falling and 1.5 – t be the time the sound... show more
    Best answer: The speed of sound in air is 343 m/s. During the first part of 1.5 seconds, the ball falls from the top to the bottom of the hole. During the second part of 1.5 second part of the 1.5 seconds, the sound rises from the bottom to the top of hole. Let t be the time the ball is falling and 1.5 – t be the time the sound is rising.

    For the ball, d = ½ * 9.8 * t^2 = 4.9 * t^2
    For sound, d = 343 * (1.5 – t) = 514.5 – 343 * t
    These two distances are equal.

    4.9 * t^2 = 514.5 – 343 * t
    4.9 * t^2 + 343 * t – 514.5 = 0
    t = [-343 ± √(343^2 – 4 * 4.9 * -514.5)] ÷ 9.8
    t = [-343 ± √127,733.2] ÷ 9.8
    t = [-343 + √127,733.2] ÷ 9.8

    The time is approximately 1.47 seconds.

    For the ball, d = 4.9 * (343 + √127,733.2] ÷ 9.8)^2
    The distance is approximately 10.6 meters.

    OR

    d = 514.5 – 343 * (-343 + √127,733.2] ÷ 9.8)
    The distance is approximately 10.6 meters.

  • What would happen if a nuclear power plant explodes in a small town?

    I live in a small town and they are putting in a nuclear power plant. My imagination tends to run wild so I was wondering what would happen if it explodes. Will it cause radioactive problems, or will it not cause any problem?

    ball, what is it that keeps it moving through the air? I understand weights, like on scales, pivoting. Also how electrons can repel one another. But it's the point passed initial contact that confuses me. I've tried looking up momentum and velocity but it just outlined the way that they work, not really an answer to this. Is the explanation on a particle level? I want to know how, if you caught one ball that had been hit by a bat, and another that was simply dropped, on video, and paused it to show both balls near one another. While both balls are basically the same in appearance, mass, etc. - scientifically, what is it about the bat-ball bat means it will soar on, not drop straight down like the dropped-ball? Thank you for all answers

    Best answer: Answer: Light behaves as a wave when observed in the double slit experiment.

    What we do know is that the fringe pattern formed on the screen during the double slit experiment shows the wave nature of light. Only waves may produce this pattern and not corpuscles.
    This fringe pattern may be reproduced in a liquid medium under experimental conditions to show that waves that are out of phase tend to cancel one another and thus form the double slit experiment pattern of light on the screen.

    According to the laws, the more the energy of a wave in a medium, the shorter is its lambda. When two waves merge, the energy increases and the lambda shortens marginally, causing a phase shift. The Dark Lines occur at points of resonance.

    Best answer: You need to use the terms used by Sir Albert Einstein and the meaning would sink in after a decade or so of studying physics.
    GRAVITY is a pucker (or dip) in the fabric of space time.

    1821SJ10
    First read this which you may not understand: Space time is created by force fields that tend to converge by gyrating into a point mass. At the central point (center of gravity), the converging forces that spiral in form a dome (GRAVITON) that compresses the forces upward into the Y-column also called the pole or magnetic axis pole. Now after reading this which you may not understand, fit in a pucker in this model. Each time a dip forms, some volume is transferred away and this allows trans-location due to gravitation.

  • Aren't we creating Energy from an electric motor that receive a horse power for one hour of work produced?

    Best answer: We are TRANSFORMING energy not creating it.
    We take a kw hr of electrical energy and with a good motor we might get 70% of that as work done.
    The other 30% is lost as heat.
    So rather than creating energy we are LOSING useful energy.
