Science & Mathematics - 12 December 2007

I got the data logger and it does not have the program that can make the report of the distance between each point so I export the CSV file and open it in excel.However, I have search about how to calculate the distance and got the formula.Then I use it with my data ;however, the result does not quite make sense to me.
I am not sure that I use the right formula or not? If not what is the right one?
What the unit of the distance ? (km,m or miles)

Click the following link to see my screens hot.

Please write the formula in the excel format so that I can understand how the calculation works. For example, the first record and the second record as the example.

I think it was a mother ringtail possum and it's baby. All that's left of both is the head, stomach and intestines and a smear of blood. I noticed the first when hanging out the washing under the house. The other was near the carport. Foxes have been seen in the area. I can't imagine a cat eating such a big meal. Any suggestions?

#1
Find c that makes
x^2 - 8x + c
a perfect square trimonial, then write as binomial

#2 solve by completing square
x^2 - 12x + 4=0

#3 complete square
2x^2 + 8x -1=0

What are people's thoughts on here about Garret Lisi's paper? It is pretty interesting. At least there are some predictions that the LHC can test.

I tried asking this question before and just got yelled at by a bunch of people telling me how stupid it is to try to interact with a wild animal, especially a big cat. Before you yell at me some more, though, listen. I am NOT going to ever buy/touch/get close to a big cat, nor am I saying that anyone should. I know they're better off in the wild and that lots of people treat them cruelly and they're life-threatening if you get close, etc. etc. etc. BUT
I am writing a FICTION novel that has big cats in it (not endorsing interaction with wild animals, by the way), and I want to know for purely THEORETICAL purposes, what your most interesting moment was interacting with one or more big cats. I will give a "thumbs-down" to anybody who chews me out about the evils of interacting with big cats, because I'm NOT DOING IT, and NOT GOING TO DO IT, and NOT ENDORSING IT!!!!!!!!!!!!!!!!!!!!
Thank you very much.

1.Space Traveler whose mass is 75kg leaves the earth.compute his weight?
a. on earth b. on mars,where g=3.8m/s

2. A box of mass 0.6 slug is moving w/ a constant velecity of 15ft/s on a horizontal surface.The coefficient of sliding friction between the box and the surface is 0.20.what horizontal force is required to maintain the motion?

3. A dictionary is pulled to the right at consstant velocity by a 10N force acting at 30% above the horizontal.the coefficient sliding friction between the dictionary and the surface is 0.5.What is the weight of the dictionary?

assume an earthquake wave has a frequency of 2 Hz. Seismic velocities in the rock of your area range from 1000 m/s to
10 000 m/s. construct a graph of wavelength versus seismic velocity for your area, To do this remember
velocity = wavelength x frequency

If a building is safe from earthquake damage ONLY if it is shorter that one-fifth of a wavelength, what is the largest building you can build in the area

PLEASE HELPPP!P!P!P!P!P!P!P!!P!P!PP!!

Lets pretend the mean weight of a cat is 10 stone (I know, its a pretty heavy cat haha) with a standard deviation of 1.5 stone. The mean weight of a dog is 8 stone with a standard deviation of 1.2 stone.

If I took one cat and one dog and put them in a box, how can I find the standard deviation of the difference in weight? How can I find what percent of dogs weigh more than cats?

Triangle ABD’s BD is an opposite, AB is adjacent, AD is hypotenuse & angle ABD is 90 degree & AB = 6 cm. But in the line AD has point C & angle BCD is 90 degree. Show that CD = 6 (sec theta – cos theta).

How can I show this?

I have done a Cap GC analysis of Xylene mix.

I have the Chromatogram and the chromatogram report which shows the retantion time peak area and area%.

how can I calculate the relative peak area from the above information?

is the relative peak area meance the area on the chromatogram report?

Ive lived in Chicago, Illinois now for 15 Years and every year its chilly/cold alot around this time and with snow.

Since last year it did not snow as much as the past years i have lived here with not alot of snow and as cold.

Now this year it has only snowed 1 time about 1 week ago and it has already almost completely melted when around this time its usualy alot of snow and in feet size of height.. right now theres none, and it also warmer than last year and the other years passed.. ive been using a sweater mostly till now since it hasnt been cold some days and till now.

But could all this be because of Gloal Warming or just something random thats happening around here?

~Thx~
