Whilst watching the olympics and other various athletics events I have always pondered this question: If the Earth spins on its axis at a high rate (I presume it must be at leat a few metres per second), why if a long jumper jumps against the direction the earth is spinning doesnt he jump out of the stadium! Or if he jumps in the direction the earth is spinning doesn't he travel backwards? If anyone has a simple explanation other than just one word - 'gravity' then I would like to hear it!

I see on the telly, various chefs and what not saying thisis how you boil an egg.

Some of them say, get the water boiling, then drop your egg into the water and boil for 2 minutes. now, when you pop your egg into the water, the egg will affect the temperature of the water. If you have a pan and drop 6 eggs into the water, this will have a greater affect on the templerature of the water.

Therefore, my hypothsis is, what is the optimal amount of water you need per egg, so if you are adding 6 eggs, the temperature fo th ewater is not affected enough to affect the outcome of your egg boiling.

a formula would be good :-)

A bath is filled up with hot water, say 42 degrees C. A volume of cold water is added, taking the temperature down to 38 degrees C.

As a proportion of the water that is already in the bath, how much hot water (42 degrees C) will be needed to bring the whole bath back up to 42 degrees C.

If you could show your working and explain any laws you are using that would be great.

It's a very famous concept that was drawn up nigh on 100 years ago and I have no idea what it means or why I should.
Seems the original theory of Special relativity said that if two people are standing looking at each other from across the gulf of space then they cannot say if the other person is moving or not.
Seems reasonable, the gulf of space is a long way to look for somebody.
Then Einstien said that planets etc cause dents in spacetime relative to their weight or gravity or something, and that all things are subject to the same laws of physics no matter what speed they are moving at, and something about the speed of light in a vacuum.
I still don't understand any of this.

when we go near the edge of the window from which sun rays are coming, our shadow is observed to be pulled by window edge asshadow is under tension.this phenomenon seems to much similar as two drops of water kept near each other forms elongation at apoint of just touching each other

Is software on your hard disk SOLID LIQUID OR GAS?

One stores data and the other stores power. So there should be something in common that allows you to store both in the same physical medium yet be able to transmit it from place to place, just as the electrical cable can transmit power and the network cable can transmit data?

Or could you choose to strip off layers (or put them on again quickly, depending on who you're looking at) at will? What I can't understand is that if you could see through everything then surely you wouldn't be able to see anything, it would be like being blind which would be rubbish.

Maybe I am using the wrong terminiogy for what I am trying to explain but I am just curious. Has it changed at all or is it entirely dependent on the spin of the earth? My husband gave me a funny look for this one. o_O

A hunter wusges to cross a river that is 1.3km wide and that flows with a speed of 6.4 km/h. The hunter uses a small powerboat that moves at a maximum speed of 14km/h with respect to the water. Draw the vectors to scale on a graph to determine the answer. What is the time necessary for crossing if the boat goes directly across the river? Answer in units of min. Your answer must be within +/- 5%

I don't get this problem... Please solve it for me or give me a way to solve this... Thanks!
