What are the two postulates of special relativity? (Choose two answers.) A In any closed system, the total momentum will not change. B F=ma (c) The entropy of an isolated system will always increase over time. The speed of light is the same regardless of the speed of the observer or the speed of the source. Light travels to us from the hands of the clock. If we could move away from the clock at the speed of light, time will appear to stand still. If you measure both the position of a particle and its momentum, then the product of the F uncertainties of these two measurements must always be at least half of the reduced Planck's constant. For all possible paths between two points, the actual trajectory is the one that results in the action being minimized.
Jupiter's moon Io has active volcanoes (in fact, it is the most volcanically active body in the solar system) that eject material as high as 500 kmkm (or even higher) above the surface. Io has a mass of 8.93×1022kg8.93×1022kg and a radius of 1821 kmkm. Part A How high would this material go on earth if it were ejected with the same speed as on Io? (RERE = 6370 kmkm, mE=5.96×1024kgmE=5.96×1024kg) Express your answer with the appropriate units.
You are the pilot of a spacecraft intended for travel at very high speeds. Before leaving you measure the spacecraft to be 31.4 m long and have a mass of 5.28 x 104 kg. During your travel, you pass a planet and exchange information with an observer on the planet. You are told that your spacecraft has been measured to be 28.6 m long. a. How fast is your spacecraft travelling with respect to the planet? b. You are told there is a nearby planet that is stationary with respect to the first planet. The observer on the first planet says it will take you 25 s to reach the nearby planet. How far away does your co-pilot on the spacecraft say the nearby planet is? c. How much energy was required to accelerate your spacecraft to this speed?
