Atheory is a framework of ideas and assumptions used to explain some set of observations and to make predictions about the real world. each of the three theories for the formation of the moon lead to different predictions about evidence that we should find. which predictions should be true if each theory is correct?

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
