Once more a mysterious metallic sphere has come to ground in Kansas, and the citizens of Hoxie have called in your consulting firm for help in identifying the material in the meteorite, which appears to have magnetic properties. You rush to Hoxie to investigate, but unfortunately your Hall probe device fails, leaving you with only a strong bar magnet and a sensitive compass. Nevertheless, you manage to identify samples from three parts of the meteorite as being diamagnetic, paramagnetic, and ferromagnetic. For your later report, you jot down the measurements and observations you made to establish the identifications. Briefly summarize these for the:

A. Diamagnet
B. Paramagnet
C. Ferromagnet

To place a communications satellite into a geosynchronous orbit at an altitude of 22,240 mi above the surface of the earth, the satellite first is released from a space shuttle , which is in a circular orbit at an altitude of 185 mi, and then is propelled by an upper-stage booster to its final altitude. as the satellite passes through a, the booster's motor is fired to insert the satellite into an elliptic transfer orbit. the booster is again fired at b to insert the satellite into a geosynchronous orbit. knowing that the second firing increases the speed of the satellite by 4810ft/s, determine (a.) the speed of the satellite as it approaches b on the elliptic transfer orbit, (b.) the increase in speed resulting from the first firing at a.
