The gravitational force of attraction between two masses m and M at a distance apart of R is:
F = GmM/R^2.
Where G is the universal gravitational constant. Suppose that m is the mass of a rocket which decreases as it burns up its fuel, and that M is constant.
(a) Calculate and ponder the meaning of:
F_m =
F_R =

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

the tires are rotating at 0.434 rpmlinear speed=45 m/sdiameter=0.550 mradius=0.275 mnow v= rωω= v/rω=45/0.275ω=163.6 rad/sω=163.6 rad/s (1rev/2π rad) (60s/1m)ω=1563 rpm

i think its d if wrong im sorry
