Science & Mathematics - 5 January 2007

I was recently at a club and as I stood there watching the laser show it appeared as if plugs of laser light were traveling thru the smoke. They moved from the origin thru the smoke, reflected off of a mirror and where redirected to the opposite end of the room. The "plugs" or "bullets" appeard to be about the size of a can of spray paint. They also appeared to travel about as fast as a bird flying across the room... like I could dodge them if I wanted to. My question is how. How did they appear to travel as bundles and how did they appear to travel at such a slow speed. A typical laser would have shown a solid stream of light either on or not on, right?

this is str8 from the paper,,analyze different given areas. complete the questions and make drawings as required . before you determine some possible dimentionss for an area of 150,000 acres lets start with some simple problems.

1. suppose you look in the real estate section of the newspaper and read that a house for sale is located on 4 acres of land:

(a) what portion AND what percent of a square mile is four acres

(b) how many square kilometers, square feet, AND square yards your answer in part (a) represent.

(c) explain how you arrived to your answer , show all calciulations.

I know how a circle can spin forever, returning to places they would before. But I don't know how something would be forever as a "line".

Who believes that the world will end December 2012 because the mayan people predicted this a couple thousand years before now and they also predicted World War I and II. This is just an opinion question and yes you should freak out. =)

And also...


7. Atmospheric pressure p at an altitude a is given by:

p(a) = p(sub o)e ^ -0.00005a

where p (sub 0) is the pressure at sea level = 14.7 lb/in^2. Explain how a barometer, or some device for measuring armospheric pressure, can be used to find the height of a skyscraper.

Is there any way to tell whether or not you would make a good surgeon before you begin all the years of training? What qualities are the most important to possess? Is it worth all the time and effort put in?

El Nino has after effects on Brazil and Argentina but why does it even affect these areas in the first place, there are water surpluses of 300mm but diagrams which show the effects of El Nino only show the west coast of South America and don't mention Brazil and Argentina, on the east coast. Please help. And if you could perhaps do something else about water surpluses in east Africa, weak monsoons in India and/or fewer, weaker hurricanes affecting the USA's east coast please do so. Thanks in advance people.

I used the feature SinReg and came up with :
y=a*sin(bx+c)+d
a=1.543405174
b=.4515057809
c=-.0047737648
d=2.114463735

I know amplitude equals a, but how do I find Period, Maximum and Minimum?

I'm doing a science project in my Biology class involving Radish plants & different colored light [white,blue & red].

The point of my project is to see if light affects the way radish plants grow & their survival rate after a month.

I would greatly appreciate if you guys could help me come up with a catchy title. Thanks.
