A 26 year-old biologist makes a trip to study life forms in a distant planet 18 light-years away. The round trip including a stay of 1 year in the distant planet takes 40 years according to the clock on earth. The biologist's son is 2.5 year-old when she left. Assume that the planet is not moving with respect to earth. How fast is the spaceship traveling? (in terms of the speed of light) How old is she when she returns...

A 22 year-old biologist makes a trip to study life forms in a distant planet 18 light-years away. The round trip including a stay of 1 year in the distant planet takes 40 years according to the clock on earth. The biologist's son is 2.5 year-old when she left. Assume that the planet is not moving with respect to earth. 1.How fast is the spaceship traveling? Give your answer in terms of the speed of light. You do not need...

One of a pair of 26-year-old twins takes a round trip through space while the other twin remains on Earth. The traveling twin moves at a speed of 0.93c for a total of 35 years, according to Earth time.a) Assuming that special relativity applies for the entire trip (that is, neglect accelerations at the start, end, and turnaround), what are the twins' ages when the traveling twin returns to Earth? B)Assuming that special relativity applies for the entire trip (that...

Jacob is 20 y old when he takes off on a road trip space voyage at a speed of .8 c to a star and come back to earth at age 27 as his time measured in moving frame. His twin sister who stayed on Earth will find her age diff from Jacob. What will be her twin sister's age when Jacob return to Earth from space voyage.

I. Darth Vader's parking problem (Part I): Darth Vader "drives" his Star Destroyer of length = 2,200 m home. He tries to park the spaceship in his newly-build garage, which is at rest. The contractor who build the garage messed up the blueprints and made the garage only 2,000 m long (the poor guy must not have known who he was working for). Darth Vader apporaches the garage at very high speed (close to the speed of light). From the...

3. a) As shown in Figure 3a, a hibernating astronaut in a ship at rest lies on a recliner making an angle = 35° with the horizontal. The height of the recliner is y = 1.15 meters. In Figure 3b, the ship is moving at velocity v = 0.75c with respect to a stationary observer. Calculate the value of the Lorentz factor y. What is the observed angle e' of the length-contracted recliner? Figure 3b. Relativity: 1 - 22 ť=yto...
Except for a few pigeons, Central Park was deserted
Except for a few pigeons, Central Park was deserted. Mist hung above the chilled grass. Patches of old snow, scattered here and there, looked like white puddles. The sun hung just above the horizon, casting red and orange streaks across low-hanging clouds. The portly, gray-haired gentleman jogging down the path looked out of place. For one thing, he was dressed in ordinary street clothes, not a sweat suit. Also, every few seconds, he looked anxiously back over his shoulder. Coming...
