Indiana Jones is searching an underground tomb for the Eye of Klaatu. He comes across two seemingly identical potential artifacts: a jewel in the center of a heavy steel framework. One is the Eye of Klaatu; it has a diamond in the center. The other is a fake and has a cubic zirconia in the center. Cubic zirconia is twice as dense as diamond, but the steel frame is so heavy that Indy can't tell by holding which one is heaver and he can only carry one out. Indy finds a fallen wooden beam that can act as a straight ramp, so he rolls both artifacts down the ramp from rest at the same time and object A reaches the bottom first. Which one is the true Eye of Klaatu? Explain your reasoning. The B-36 Peacemaker was a strategic bomber airplane built for the US Air Force from 1949 to 1959. The first prototypes had a landing gear that consisted of a single large wheel as shown in the diagram. Later models replaced the single large wheel with four smaller wheels. The large wheel (a cylinder) has radius R and height L. Each of the four smaller wheels has radius R and height L. The big and small wheels all have the same density. When the big wheels were replaced with the smaller wheels, it was found that the bomber reached its take-off speed in much less time. Explain why this would be the case. Include specific calculations. Object A Big Wheel SRI Object B Four Small Wheels Indiana Jones is searching an underground tomb for the Eye of Klaatu.
