Unformatted text preview: Chapt. 14 Gravity 127 014 qmult 00686 1 3 3 easy math: fiducial-value orbital speed 2 (fo2) Extra keywords: A test follow-up to fo1 !!! It can only be given as a follow-up!!! 29. Plutos mean radius of orbit around the Sun is 39 . 48168677 AU (Wikipedia: 2007sep25), where 1 AU is the mean radius of the Earths orbit around the Sun. What approximately is Plutos orbital speed? a) 1200 km / s. b) 30 km / s. c) 4 . 7 km / s. d) 0 . 75 km / s. e) 200 km / s. 014 qmult 00720 1 1 3 easy memory: gravitational PE of a point mass 30. The inter-object gravitational potential energy of two spherically symmetric masses of mass M and m with center-to-center distance r (with PE for r = being zero as is conventional) is given by: a) PE = GMm r 2 . b) PE = GMm r . c) PE = GMm r . d) PE = GMm r 2 . e) PE = GMm 2 r . 014 qmult 00730 1 1 1 easy memory: grav PE localizable distribution 31. If one has a localizable set of point particles or objects that can be approximated as point particles, the total potential energy of the set is...
