N was just a constant my professor gave us. It's just hypothetical. How does this force compare to the actual distance between the two galaxies
Thanks for everyone's help!
Oh I know that galaxies aren't perfect spheres, but this problem is for an intro astronomy course.
I'm still unclear what gets plugged in where...
M1=mass of andromeda
m2= mass of milky way
G= 6.7 x 10^-11
so I solve for d^2?
there Is a force causing the andromeda galaxy and the milky way to move away from each other with a magnitude of 2x10^28N. How close must the galaxies be to each other for the force of gravity overtake this repulsive force?
Mass of andromeda=
6 x 10^41
Mass of milky way= 3 x 10^41...
If Mork decided he wanted to go home to his planet Ork (10 light years away) and
traveled at 99.1% of the speed of light, while Mindy stayed in Colorado, who would have
aged more, Mork or Mindy, in the following situations.
a. If Mork went to Ork and returned to Colorado. Who would...
