Objects that are at rest relative to Earth's surface are in circular motion due to Earth's rotation. What is the radial acceleration of a painting hanging in a museum at a latitude of ϕ = 38.9° North? (Note that the object's radial acceleration is not directed toward the...
well i don't know how to find the height but for the acceleration i know if
G= 6.67*10^-11
M= 5.97*10^24
then V=sqrt((GM/r)
but my solutions don't seem to be working
i am comlpetely stuck on this problem
Two satellites are in circular orbits around Jupiter. One, with orbital radius r, makes one revolution every 16 h. The other satellite has orbital radius 4.0r. How long does the second satellite take to make one revolution around Jupiter?
any help please?
