In an experiment to test for conservation of momentum, the total momentum of a system is measured before and after a collision. suppose that a graph of final momentum (pf) vs. initial momentum (pi) is made. if the hypothesis is that momentum is conserved during the collision, make a quantitative prediction of the slope and the vertical intercept of the trendline that the data should be expected to follow.

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.

Much of the information taught in earth-space science would not be available if it weren’t for our remote sensing abilities. explain two ways our remote sensing strategies contribute to our knowledge of these topics.

Which accounts for an increase in the temperature of a gas that is kept a constant volume
