Suppose an astronaut travels to a star 10 lightyears away at a significant fraction of the speed of light (for example, v=0) and returns. Assume the negligible amount of time is spent at the destination.

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...
Astronaut Flo wishes to travel to a star 20 light years away and return. Her husband Malcolm, who was the same age as Flo when she departs, stays home (baking cookies). If Flo travels at a constand speed of 80% of the speed of light (except for a short time to turn around), how much younger than Malcolm will Flo be when she returns?Hint--How long does Malcolm sit around baking cookies? How far is the distance to Flo?
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...
This question is to be solved in Python. Question 1 10 points): Purpose: To practice recursion with a simple example Degree of Dificuity Easy The evil Team Rocket has invented an incredible new space-ship! The ship works as follows . If the distance to the destination is greater than 1 meter, the ship will Told space' and 'jump to a position exactly half way to the destination It takes exactly one minute to perform this process e Any distance of...
choose correct answer. no explanation needed QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...
Case 27 To Use or Not to Use? Beaufort Sea Production Company (BSPC) operates a medium-sized oil field on Alaska’s north coast. The field is still producing at its maximum rate, 325,000 barrels of oil per day (BOPD). However, to sustain this rate the company started a waterflood of the reservoir two years ago. Now a capacity bottleneck in the water disposal process is threatening to curtail production. In waterflooding, salt water from the Beaufort Sea is treated to remove...

Zipcar: “It’s Not About Cars—It’s About Urban Life” Imagine a world in which no one owns a car. Cars would still exist, but rather than owning cars, people would just share them. Sounds crazy, right? But Scott Griffith, CEO of Zipcar, the world’s largest car-share company, paints a picture of just such an imaginary world. And he has nearly 800,000 passionate customers—or Zipsters, as they are called—who will back him up. Zipcar specializes in renting out cars by the hour...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
