Ou are writing a short adventure story for your english class. in your story, two submarines need to arrive at a place in the middle of the atlantic ocean at the same time. they start out at the same time from positions equally distant from the rendezvouspoint. they travel at different speeds, but both go in a straight line. the first submarine travels at an average speed of 20 km/hr for the first 500 km, 40 km/hr for the next 500 km, 30 km/hr for the next 500 km and 50 km/hr for the final 500 km. in the story’s plot, the second submarine is required to travel at a constant velocity, so the captain needs to determine the magnitude of that velocity. what is that velocity?

[05.02] what is the best explanation of the kinetic molecular theory as it relates to the energy of the molecules in the states of matter? (1 point) the molecules in a gas have greater kinetic energy than those in a liquid, which in turn have greater kinetic energy than the molecules in a solid. kinetic energy cannot be created nor destroyed, and, as a result, all states of matter have the same kinetic energy. the molecules in a gas have greater kinetic energy; therefore, they are more tightly packed than the molecules in either a liquid or a solid. the molecules in gases and liquids, in constant motion, have greater kinetic energy than those in a solid, which do not move or vibrate because their position is fixed.
