1.In a rectangle ABCD, AB=100 and BC=70. A beam of light leaves a and travels through P which has perpendicular distance 3 and 4 from AB and AD respectively. The beam is reflected every time it reaches a side of ABCD. How much distance would it travel before hitting a vertex?

2.S is a set of some integers and includes 1 and 2002. For every integer contained in S, the average of the remaining integers in S is also integer. What is the maximum possible number of integers in S.

I've been wondering this for a long time because coyotes in the east are as much as 2 times larger than the coyotes in the west. I have heard that eastern coyotes are not true coyotes but a coyote/wolf hybrid. Is this true? In the east some coyotes have grown as large as a german shepard. And coyotes in the east have been know to kill large prey like deer, and even cattle!

How could one capture massive amounts of CO2 from the atmosphere - what chemical reactions are there that could be used? Obviously there is the risk of reversing the problem of greenhouse gases so much that plant life is at risk, but if the process was limited to just in power stations or in cars - how could one do it?

I have a confusion...

My teacher taught us that when we are drawing a Lewis Dot Diagram, we would start from the top then go clockwise, putting 1 dot each time for every valence. If more than 4, then we would start from the top again, adding 1 more dot beside the previous dot(s).

For example, if according to my teacher, let say:

Hydrogen (H)
the dot should go above H, right?

or

Oxygen (O)
there should be 2 dots above, 2 dots on the right, 1 dot at the bottom, and 1 on the left, right??

_------------------------

However, when I searched upon the internet, there seems to be differences from mines...why?

example from site: http://www.uoregon.edu/~ch111/images/dotsstruct.gif

Please explain...this is urgent for a project
