• How do I accelerate a toy car?

    I would like to know if you accelerated it by means of weight or maybe not also by propulsion

  • Could a light sail be used to propel ground vehicles?

    Best answer: No. The impulse of a photon is so very very ... very tiny, that it would take a light sail the size of several city blocks to collect enough photons to create sufficient impulse to accelerate a small vehicle.

  • How loud would a sound have to be in order to be heard on the other side of the planet?

    Is it even physically possible? Wouldn't the sound itself (difference in air pressure) have a destructive force like a shock wave? I'm thinking either a meteor striking the earth or the loudest loud speaker imaginable.

  • Why do I hear sonar beeps at night sometimes?

    Sometimes if I'm up late at like 2 am or past that, I hear the sounds of sonar beeps in a submarine the whole night until day comes. It's more spaced out and faint, but I'm not sure what it is. There's nothing obvious I live near that makes that sort of sound.

    it is often useful to have a mirror with a larger than normal field of view
    one such application is the outside mirror on the passenger side of some vehicles
    in order to get the larger view
    the mirror is slightly convex
    convex mirrors produce reduced, upright, virtual images

  • GRAVITY...falling objects fall at the same speed in a vacuum? But surely heavier objects have more gravity and therefore would fall faster?

    So, I have always understood that falling objects like a feather and egg fall at the same speed in a vacuum. However,the egg having more mass should have more gravity and therefore a stronger gravitational pull towards the earth. I read somewhere that falling objects basically don't have gravity, which seems... show more
    So, I have always understood that falling objects like a feather and egg fall at the same speed in a vacuum. However,the egg having more mass should have more gravity and therefore a stronger gravitational pull towards the earth. I read somewhere that falling objects basically don't have gravity, which seems silly. Doesn't everything have gravity? If everything has gravity and things with higher mass have more gravity then surely heavy things fall faster.

  • Do magnets work in outer space, or is magnetism something that is indigenous to Earth?

    I'm guessing a compass wouldn't work in outer space due to not having the Earth's magnetic field to align itself with, but do magnets even work in space in the first place? Or do they suddenly become demagnetized chunks of rock or metal(not sure what they consider magnets as, maybe rock)

  • Name the rays which are considered death rays? a) X-Rays b) laser rays c) Gamma rays d) Ultra violet rays?

    Best answer: Gamma rays are most dangerous, I'm pretty sure. However, UV rays can also be damaging in excess. Because of this, I would guess Gamma rays are most likely to be called 'death rays'.

  • Stephen Hawking Philosophy Question.?

    Physicist Stephen Hawking claims that the idea of god is useless to explain why the universe was formed.

    Physicist Stephen Hawking claims that the idea of god is useless to explain why the universe was formed. He writes: “Because there is a law such as gravity, the Universe can and will create itself from nothing. Spontaneous creation is the reason there is something rather than nothing, why the Universe exists, why we exist.” Let’s assume he holds some version of the view that something came from nothing: (i) Evaluate Hawking’s position that something can come from nothing, explaining the potential flaws with this view. (ii) Of the two opposed positions (a) something existed forever and (b) something came from nothing, explain which position you find more plausible and why.

  • If one were to sexually orgasm in space, would the kinetic energy cause the individual to be propelled in a backwards velocity?

    Best answer: Vibrating gas molecules cause air pressure. Each and every collision imparts a momentum away from each other. Unless there is some bonding as there is in solids, the thermal vibration causes the repulsion of gas molecules. Now there is no fundamental difference. If you are vibrating back and forth then you will... show more
    Best answer: Vibrating gas molecules cause air pressure. Each and every collision imparts a momentum away from each other.
    Unless there is some bonding as there is in solids, the thermal vibration causes the repulsion of gas molecules.

    Now there is no fundamental difference. If you are vibrating back and forth then you will repel your partner.
    Without some attractive force holding you together you will never get the opportunity to orgasm in space.

    Which brings us back to the same fundamental law of sex. Unless you are attractive you end up not getting any.
