... Assuming that the mass of the Eagle module is constant during its ascent and equal to 5000kg (of which 2700kg is fuel) and that the acceleration due to gravity on the moon, g=1.6ms-1, is assumed to be constant during the ascent, calculate the work required to lift Eagle to the command module. By how ...

Honors Question – Black Holes and Neutron Stars In Friday`s lecture
... In Friday's lecture, we learned that physicists think that black holes are mass singularities – an enormous mass concentrated in essentially a point. Since gravitational force increases as the distance decreases, it's natural to conclude that within some radius the gravitational force is so large th ...

Fluid Instabilities
... • Inviscid case: Rayleigh Criterion (1917) • Viscous case: Taylor Criterion (1923) • Magnetic case: Velikhov (1959)/Chandrasekhar(1961) Couette Flow: a fluid confined between two cylinders which rotate at different rates. Results apply to accretion disks. ...

I have heard people call Jupiter a "failed star" that just did not get big
... Stars form directly from the collapse of dense clouds of interstellar gas and dust. Because of rotation, these clouds form flattened disks that surround the central, growing stars. After the star has nearly reached its final mass, by accreting gas from the disk, the leftover matter in the disk is fr ...
