Maybe it's "normal" for things to work in waves on a quantum level, just like it's "normal" for objects to travel in a straight line in classical physics. I'm not saying that explains anything, but it seems like there might be some underlying principle that connects all of the phenomena you...
The reason coffee isn't as good as drinking plain water for hydration is because caffeine is a diuretic and prevents your body from absorbing as much water. I suppose if you drank enough of it that wouldn't be a problem...=P
Think about what numbers could be rounded up or down to get these numbers, for example the biggest number that rounds down to 0.30 must be less than 0.305. The smallest number that can be rounded up to 0.30 is 0.295. So 0.30 is plus or minus 0.005.
0.005 is 1.67% of 0.30.
Thank you all for your replies. I still don't understand why tidal force falls off at 1/distance cubed. Is there a formula for that? Can you please explain?
Homework Statement
The gravitational attraction of the Sun and Moon on the Earth produces tides. The Sun's tidal effect is about half as great as the Moon's. The direct pull of the Sun on the Earth, however, is about 175 times that of the Moon. Why is it that the Moon causes larger tides...
