Kepler's Laws and the Motion of Planets

AI Thread Summary
To determine the orbital period of an artificial satellite in a circular orbit where the acceleration due to gravity is 9.00 m/s², one must first calculate the altitude of the satellite above the Earth's surface. This involves using gravitational equations to find the radius of the orbit. Once the radius is established, the orbital period can be calculated using the formula that relates distance and orbital periods. The discussion emphasizes the importance of understanding the relationship between gravitational acceleration and orbital mechanics. Proper calculations and application of Kepler's Laws are essential for accurate results.

You could start by figuring out how high above the Earth's surface that satellite may be, and then using some equation that relates distance and orbital periods.
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
