Physics
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 Space Station. Due to mishandling of units by a technician, you find yourself...

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...

So will the aphelion be the perihelion + 2a = 31,410 km?? In order to calculate the period, won't I need the velocity?

I'm sorry, you are right, I omitted some words, here is the question: 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...

Um..... I thought it was because he was the symbol of preventing wildfires, but I thought it had to be bigger than that. I know he is trying to promote stopping wildfires to save our ecosystem, but the popularity question confuses me. I mean, I pretty much know, but I can'...

Why has Smokey the Bear been popular for so long? What does he try to promote?

Physics
A beam, B1, of mass M1 = 0.6887 kg and length L1=1 m is pivoted about its lowest point at P1. A second beam, B2, of mass M2=0.200 kg and length L2=0.200m is suspended (pivoted) from B1 at a point P2, which is a horizontal distance d=0.550, from P1. To keep the system at equili...
