Science: You and some friends are at the park. You find some rope and decide you'd like to play a game of tug-of-war. Unfortunately, there are 5 people so you can't have an equal amount of people on each team. One of your friends suggests that the two biggest people should be on one side, while the three smaller people should be on the smaller side. Do you think this is a fair way to split up the teams? Why or why not?

How is the gravitational force related to the distance between two objects?

A4.0-cm tall light bulb is placed a distance of 32.0 cm from a concave mirror having a focal length of 16.0 cm. determine the image distance

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.
