Please make sure that when you finish your work for the problem, you show the work to the camera carefully. Then write “Done” in the answer box.  Evaluate the double integral

TRICKY! It is thought that many stars eventually collapse to rapidly rotating neutron stars with a density of 1.00 x 1017 kg/m3. Calculate the value of the surface gravity (acceleration due to gravity) on a neutron star. DENSITY = Mass/Volume     Mass of the star = 1.98 x 1030 kg    volume of a sphere = 4/3 π r3 G = 6.67384 × 10-11 m3 kg-1 s-2   REPORT YOUR ANSWER NUMERCALLY and its units will be x 1011 m/s2

Explain why astronauts in the International Space Station are not ACTUALLY experiencing zero gravity.
