1d collisions head on collisions sticking together ANSWER: mv - mv = collective mass x v 1d collisions in the same direction not sticking together ANSWER: mv + mv = mv + mv 1d collisions in the same direction sticking together ANSWER: mv + mv = collective mass x v 1d explosions ANSWER: mv + 0 = collective mass x v 1d recoil ANSWER: 0 = mv + mv Gun velocity will be negative as it is going back 2d collisions ANSWER: Total momentum in vertical component Total momentum...

Does the thrust of a turbojet engine increase or decrease with altitude? Why? The thrust of a turbojet engine decreases with altitude, principally because of the lower air density and hence the lower mass flow rate of air ingested into the engine. Does the thrust of a rocket engine increase or decrease with altitude? Why? The thrust of a rocket engine increases with altitude, principally because of the decrease in ambient pressure and hence the increase in pressure thrust. State ...

Exam (elaborations) TEST BANK FOR An Introduction to Modern Astrophysics By Carroll B.W. and Ostlie D.A. (Solution manual) CHAPTER 1 The Celestial Sphere 1.1 From Fig. 1.7, Earth makes S=P˚ orbits about the Sun during the time required for another planet to make S=P orbits. If that other planet is a superior planet then Earth must make one extra trip around the Sun to overtake it, hence S P˚ D S P C 1: Similarly, for an inferior planet, that planet must make the extra trip, or S ...
