So is the period 8222 s? I still don't get why the ansser for the aphelion is wrong...

Sorry for reposting this but I'm still confused with the last part... You have been sent in a small spacecraft to rendezvous with a space station that is in a low circular Earth orbit, say, with a radius of 6,720 km, approximately that of the orbit of the International Spa...

For a scene in a movie, a stunt driver drives a 1.50x10^3 kg SUV with a length of 4.35 m around a circular curve with a radius of curvature of 0.333 km. The vehicle is to be driven off the edge of a gully 10.0 m wide, and land on the other side 2.96 m below the initial side. W...

A 3.8 kg object is supported by an aluminum wire of length 1.9 m and diameter 2.2 mm. How much will the wire stretch?

Physics Question
Here is a demonstration Pascal used to show the importance of a fluid's pressure on the fluid's depth : An oak barrel with a lid of area 0.17 m^2 is filled with water. Along, thin tube of cross-sectional area 4.7×10−5 m^2 is inserted into a hole at the cent...

I'm sorry, I don't understand, you mean this equation: P = 2pi sqrt[R^3/(GM)] won't a be 12,345?

Physics
Thanks, I now get 5481 seconds for the period, then I have to multiply that by 1.5 right? I get 8222 s When you say substitute a for R, you meant for the equation of the aphelion?

Physics
I must be doing something wrong because I typed the answers for a second time and they are wrong, I have only one attempt left, can you please check what I did wrong? For the period what I did was P = sqrt(R^3(4pi^2)/GM) P = sqrt ((6720^3(4pi^2)/(6.674E-11(5.9742E24))) P = 0.1...
