Howdy, I am 40+ year old math teacher(teaching 13-16yo kids). On my old days, I decided to study some physics. I have always been interested in physics but now I am really getting into it. Sorry for my bad english...
Mass of a satellite is 750g(##m = \rho V = 8,96 \frac{g}{cm^3}\cdot (\frac{4\pi(100cm)^3}{3} -\frac{4\pi(99,9cm)^3}{3}) = \approx 750g =0,75kg##)
I am not sure what to integrate. I solved T there but it seems far stretched
$$T =\sqrt[4]{\frac{dQ}{dt}\frac{1}{e\sigma A}} $$
How to get the...
