I have always thought that if you use cold water then you're body will try to climatise by increasing your internal temperature so you will feel warmer or am I just making this up. Please help to dissolve my confusion!

a. How long did it take the rock to reach the ground?

b. Neglecting air resistance, how far did the rock travel horizontally before hitting the ground?

c. What was the rock’s vertical velocity hitting the ground?

d. What was the rock’s horizontal velocity hitting the ground?

e. What was the rock’s resultant velocity hitting the ground?

I don't want anybody to give me any of the answers. I'm really looking on how to set up the problem to get to the answer. I just started physics and I want to understand it because it's interesting but I'm having some problems. Any help is greatly appreciated. Thanks.

The spider's body is quite big.It looks like a gnaphosidae but i'm not a spider proffessor. The web is quite interesting.It's situated under the window outside and looks like a cocoon with another small webb in front of it.The spider sits next to it and doesn't move during the day.

In an atom, the electrons revolve around the nucleus in orbits. That's ok.
But in the nucleus, the protons and nuetrons stay together.
How is that possible?
I mean, nuetrons do not have any charge.
So...why aren't the protons thrown away from each other???

We've got to do a project on maths in nature... Our teacher has already given us a few ideas we could use.. for example, the cells in a bee-hive are hexagonal in shape, many things in nature are symmetical, crystals of many substances have geometrical shapes etc... But I need many more ideas to work on too.. can anybody here help???
