Rolanda sees an error in her friend’s graphic organizer comparing electrical and gravitational forces. A Venn diagram with two intersecting circles. The circle on the left is labeled gravitational force. The circle on the right is labeled electrical force. There is an X in the circle on the left with infinite reach and depends on mass. In the circle on the right is Z with depends on charge. There is a Y in the intersecting area.

Which change should Rolanda suggest to her friend to correct the error?

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.
