Science & Mathematics - 30 November 2007

This ? concerns roots. Here is the problem:

8 5/6 (this problem follows the rule of: a m/n = n, then the "square root" sign; then, inside the sq. root, a to the m power)

8 5/6= 6th root of 8 to the 5th power

So, it is the 6th root of 32, 768.

I don't have a calculator w/ me, so
I couldn't give you the answer.

Anyway, I believe that 6th root of 8 to
the 5th power is the answer (short of
solving that final part of the problem).

Assume G(X)=definite ∫ g(t)dt on the interval [a,x] is Riemann integrable on [a,b], then prove G(X) is well defined and prove or disprove G(X) is the antiderivative of g(t); i.e. prove the following statement: If g is continuous at x, then G ' (X) = g(x).

The sun has a mass of 1.99*10'30 kg, and is moving in a circular orbit around the center of our galaxy, the Milky way, dragging the rest of the solar system behing it. The radius of the orbit is 2.3*10'4 light years(1 ly=9.5*10'15)and the sun has an angular speed of 1.1*10'-15 rad/s. What is the magnitude of the net force keeping the sun moving on this path?

Hey Southern California, how do you feel about the rainy, wet and cool weather you have today? Are you going to complain about a little rain that you desparately need? Are you going to complain about the cool (not even cold) temperatures? Are you going to wish the rain should have came on another day (and on that "other" day you'd wish it should have came on yet another day)? Is this going to be the headlines of the news now? Or have you forgotten about what rain is?
