The diameter of our disk-shaped galaxy, the Milky Way, is about 1.0 105 light-years (ly). The distance to the Andromeda galaxy (Fig. PI.57), which is the spiral galaxy nearest to the Milky Way, is about 2.0 million ly. If a scale model represents the Milky Way and Andromeda galaxies as dinner plates 25 cm in diameter, determine the distance between the centers of the two plates.

Your roommate is playing a video game from the latest Star Wars movie while you are studying physics. Distracted by the noise, you go to see what is on the screen. The game involves trying to fly a spacecraft through a crowded field of asteroids in the asteroid belt around the Sun. You say to him, “Do you know that the game you are playing is very unrealistic? The asteroid belt is not that crowded and you don’t have to maneuver through it like that!” Distracted by your statement, he accidentally allows his spacecraft to strike an asteroid, just missing the high score. He turns to you in disgust and says, “Yeah, prove it.” You say, “Okay, I’ve learned recently that the highest concentration of asteroids is in a doughnut-shapedregion between the Kirkwood gaps at radii of 2.06 AU and 3.27 AU from the Sun. There are an estimated 109 asteroids of radius 100 m or larger, like those in your video game, in this region . . .” Finish your argument with a calculation to show that the number of…
true or false. I- The speed of light in vacuum is a universal constant, whose value (without uncertainty, as it is defined as a standard) is c=299792458 m.s -1..The value of c in scientific notation is 2.99792458 x108 m.s-1. II- The value of c (velocity of light in vacuum) written to 3 significant figures is 3.00 x 108 .m.s-1. III- The value of the density of an object obtained was ρ±uρ=(7.768581114 ± 0.012540242) g.cm -3. The value obtained for the density and its respective uncertainty is incorrect, as it makes no sense to report the uncertainty with so many decimal places. IV- To convert g/cm 3 to kg/m 3 just multiply by 10 3.

Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54×107 light-years from Earth. If the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed ?min to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between ?min and the speed of light ?. ?−?min= m/s
