I4 You travel to a star 185 light-years from Earth at a speed of 2.90×108 m/s . Part A What do you measure this distance to be? l = ??? ly
We know that:
l = l0 xsqrt(1-v2/c2)
c = 3 x 108
Substitute given information as follows:
l = 185 x sqrt[(1-2.9 x 108)2/(3 x108)2]
therefore:
l =47.367 ly

You travel to a star 195 light-years from Earth at a speed of 2.90*10^8m/s . What do you measure this distance to be? units ly
A star is 14.7 ly (light-years) from Earth. (a) At what constant speed (in m/s) must a spacecraft travel on its journey to the star so that the Earth–star distance measured by an astronaut onboard the spacecraft is 4.46 ly? m/s (b) What is the journey's travel time in years as measured by a person on Earth? yr (c)What is the journey's travel time in years as measured by the astronaut? yr
Part A If you were to travel to a star 155 light-years from Earth at a speed of 2.70 x 10 m/s, what would you measure this distance to be? 180 AS - OO ? Submit Request Answer
Light requires 4.5 years to travel from the nearest star to earth. If we could travel there in a spaceship going 90% of the speed of light, the trip would require 5.0 years according to clocks on earth. How much time would pass for the passengers in the ship?
PLEASE ANSWER BOTH!!! Our best measurements from Earth indicate that the star system Alpha Centauri is 4.2 light-years away. Suppose some of our astronauts traveled there at a speed v 0.83c. What would the astronauts measure as the distance to Alpha Centauri? O 2.8 light-years 9.1 light-years O 2.9 light-years O 2.3 light-years O 7.5 light-years If a proton with mass 1.67 x 10"27 kg moves in an accelerator such that its total energy is five times its rest energy...
Suppose you decide to travel to a star 69 light-years away at a speed that tells you the distance is only 28 light-years. Part A How many years would it take you to make the trip? Express your answer using two significant figures.
1. -11 points SerPSE10 38.4.0P.003. My Notes A spacecraft is to travel from Earth to a star 6.15 ly away. At what speed must the craft travel in order for the Earth-star distance to be 4.10 ly, when measured in the reference frame of the craft? Express your answer as a multiple of c, the speed of light in a perfect vacuum. ПС Need Help? Read
the sun is 1.50 x 108 km from earth, and the speed of light is 3.00 x 108 m/s. how many minutes elapse as light travels from the sun toearth?please show work
Consider a bright star in our night sky. Assume its distance from Earth is 31.7 light-years (ly) and its power output is 4.00 x 1028 W, about 100 times that of the Sun. (a) Find the intensity of the starlight at the Earth. 3.54e-8 Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. nW/m² (b) Find the power of the starlight the Earth intercepts. One light-year is the distance traveled...
In an Earth reference frame, a star is 76 light-years away. How fast would you have to travel so that to you the distance would be only 39 light-years?
