originates from an underwater diver, has a radius of 8 mm at some depth h. When the bubble reaches the surface it has a radius of 9.6 mm. Assume the temperature of the air and the bubble remain constant and that acceleration of gravity is 9.8 m/s^2.

1) Determine the this depth h of the diver in units of m, AND
2) Determine the absolute pressure at depth h in units of Pa.

Will it work, sewing another persons leg onto the place where you lost yours? It works sewing your own leg back on so why not someone elses, if your leg is unavailable?

I live and grew up in Utah. When I was little the winters
were bold and snowy, cold and white. In the past few years
they have just been brown and dry. I am saddened that my
daughter won't get to grow up with the same Winter's that
I experienced when I was a kid- months of snowmen and sledding
and catching snow flakes on your tongue. I don't know if
its because of Global Warming- because I know that the weather
has cycles that are far reaching and this could be, a 100 year
cycle or something... but when I was a kid in Utah, man we
had the best winters. Walls upon walls of snow, igloos, mittens
and snow-ball fights. Now we have brown dirt and leaves blowing
around.. only the majestic Wasatch Front is snow tipped.
Has anyone else seen such a dramatic change in the weather where
YOU live? Tell me about your observations....

How do i go about solving this?

In the vector space of polynomials with real coefficients show that {5–x, 6+x, x^2+4x+1} is a basis for the subspace of polynomials with degree at most 2. Express 5x^2+7x+3 as a linear combination of these basis vectors.

I was a weather forecaster for a few years in the military. I did everything from weather briefs to combat weather graphics, annalyzing data, Med Evacs, and actual forecasts for S Cntrl US. I've been out for three years now, but I'm curious if this is enough experience to apply for any sort of forecasting job?
