- Give the consequences of the Postulates of the General Relativity.arrow_forwardThe Millennium Falcon is approximately 35.2 m long. There are conflicting reports, but the Falcon made the Kessel Run in approximately 12.27 parsecs. This is an odd unit to measure speed with as a parsec is a unit of length equal to 3.26 light-year. The science FICTION comes in when you consider that ships in Star Wars use hyperdrive to travel faster than the speed of light, so they are able to make jumps through space. Han Solo picked difficult or dangerous points to jump between to make the trip so short. Let's imagine that the Millennium Falcon travels at 0.96c during the 12.27 parsec Kessel Run. What distance, in light-year, does an observer at the finish line measure for the trip? Don't forget to convert parsec to light-year. X light-year What distance, in light-year, does Han Solo measure for the trip as he pilots the ship? light-year Which person measures the proper distance of the trip? Which person would measure the proper length of the Millennium Falcon?arrow_forwardThere is a galactic, royal wedding in El Candrea. Maria Isabela, the princess of andalusia prima maxima, is riding a diamond-studded, pink spacetime motorcycle whose maximum speed is 5x10^2 km/s. The religious princess started her speed at about 5x10^1 km/s and she is to supposed to travel 1.78 x 10^4 km at a straight distance in about 60 seconds to reach the wedding before the galactic church closes. The princess accelerated until her max speed was reached. She then maintains the aforementioned speed till she reached the wedding gates. To reach the church before it closes, what should be her minimum constant acceleration? a. 8.30 km/s^2, b. 7.50 km/s^2, c. 5.29 km/s^2, or d. 6.95 km/s^2arrow_forward
