An astronomer is studying the eight planets in our solar system and their orbits. He wants to explain in mathematical terms the difference between Earth's orbit and Saturn's orbit in relation to one another and in relation to the Sun. Write a summary that can help him decide how to determine this information.

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

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.
