• If 2 drops of water touch is one of the drops of water wet?

    Best answer: No, because whenever two drops of water touch, they instantly become one drop of water due to the physical properties of water, specifically surface tension. I mean, I get the game of semantics you're trying to play, which--pardon the pun--also doesn't hold water, but there's actually a scientific... show more
    Best answer: No, because whenever two drops of water touch, they instantly become one drop of water due to the physical properties of water, specifically surface tension. I mean, I get the game of semantics you're trying to play, which--pardon the pun--also doesn't hold water, but there's actually a scientific reason why it doesn't, as well.

    Make your next question: "If I cut a round cake into eight pieces, do I have one thing or eight things?" That at least won't get you shot down based on simple science.

  • Which tank would be full first?

    Which tank would be full first?

    Best answer: We have to know if this is to scale. If there is "unlimited" water in the top reservoir tank a will fill first because flow rate is determined by the height of water and if the height of water in the reservoir is always higher than the height of the tanks the flow rate is higher into a than out of a and... show more
    Best answer: We have to know if this is to scale. If there is "unlimited" water in the top reservoir tank a will fill first because flow rate is determined by the height of water and if the height of water in the reservoir is always higher than the height of the tanks the flow rate is higher into a than out of a and it will fill first. If the drawing is to scale and that's all the water there is it looks like all the water will either flow out of d, be left in a full d, or be in an unfull c

  • If you were on top of the Empire State building, would time travel faster or slower relative to its base?

    Best answer: Time goes faster because you are in a weaker gravity field. Time goes slower because you are going faster as the Earth rotates. Which effect is larger? You would need to figure effect from each source. The net effect is that time is FASTER for someone farther from Earth. The number is 1.1 x 10^-9 seconds per... show more
    Best answer: Time goes faster because you are in a weaker gravity field. Time goes slower because you are going faster as the Earth rotates. Which effect is larger? You would need to figure effect from each source. The net effect is that time is FASTER for someone farther from Earth. The number is 1.1 x 10^-9 seconds per year, for each foot higher you are. Since the Empire State Building is 1,454 feet tall, that adds up to 1.6 x 10^-6 seconds per year. You could stay up there for 100 years, the difference would be less than 0.0002 seconds.

    There is a height where, for orbiting objects, time goes at the same rate, and if you go higher, time goes slower. The GPS satellites run slower by 38.64 microseconds per day.

    I know this is an impossible situation, but if a planet were that way, would laying down be possible?

  • How are thrust and drag related when a car is accelerating forward?

    Best answer: When it is accelerating there is only ONE known relationship. The thrust must be greater than the drag. There could possibly be no drag at all. That would not change very much. In most cases, except at very high speed, the thrust during acceleration is many times greater than the drag. Even on my pushbike, at... show more
    Best answer: When it is accelerating there is only ONE known relationship. The thrust must be greater than the drag.
    There could possibly be no drag at all. That would not change very much.
    In most cases, except at very high speed, the thrust during acceleration is many times greater than the drag.

    Even on my pushbike, at 10km/hr the drag is perhaps 10W at most. Yet I am putting out some 300W into the acceleration.
    When I reach my chosen speed I reduce the power but of course the drag has increased with the increasing speed.

  • How is the force of gravity responsible for the moon’s motion around Earth?

    Best answer: "EVERY body moves in a straight line with constant speed UNLESS acted upon by a force". ( Isaac Newton). This was what was behind the famous apple.

    Best answer: "EVERY body moves in a straight line with constant speed UNLESS acted upon by a force". ( Isaac Newton).
    This was what was behind the famous apple. Newton knew that there must be a force to keep anything moving in a circle.
    He knew that the moon moved in a circle. But what could the force be that kept the moon attracted to the earth without any connection?
    When he saw the apple fall he realized that gravity acts on bodies that do not touch it.
    So he rushed back and calculated some things from known orbits.
    He concluded that the force COULD be gravity. But only if gravity reduced with increasing distance from the earth.

    In fact it had to reduce according to 1/R^2 if it was to explain Kepler's Laws.

    A little more work and the conclusion was F = GMm/R^2 where G is some form of universal constant.
    that is Gravity could be the cause of all orbits if this formula accurately described it.

    It was left to Cavendish to actually perform the experiment and find the value of G.
