The eight figures below show spheres that have been thrown horizontally, i. e., straight out, off cliffs. All of the spheres are the same size and have the same mass, but they are thrown at different speeds off cliffs of
different heights. The specific speeds and heights are given in each figure.

Rank these spheres from longest to shortest on the basis of how long they take to reach the ground. That is,
put first the spl ere that takes the most time in the air, and put last the sphere that takes the shortest time
in the air.

Which of the following is a source of heat for magma formation? magma plumes in the continental crust friction due to divergence friction due to subduction magma plumes in the oceanic crust

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.

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
