If astronauts could travel at
v = 0.951c,
we on Earth would say it takes
(4.20/0.951) = 4.42
years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree.
(a) How much time passes on the astronauts' clocks?
years
(b) What is the distance to Alpha Centauri as measured by the
astronauts?
light-years
If astronauts could travel at v = 0.951c, we on Earth would say it takes (4.20/0.951)...
26) If astronauts could travel at v = 0.950c, we on Earth would say it takes (4.20/0.950) - 4.42 years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree. (A) How much time passes on the astronauts' clocks? (B) What is the distance to Alpha Centauri as measured by the astronauts?
If astronauts could travel at v = 0.945c, we on Earth would say it takes (4.20/0.945) = 4.44 years to reach Alpha Centauri, 4.20 light-years away. The astronauts disagree. (a) How much time passes on the astronauts' clocks? years (b) What is the distance to Alpha Centauri as measured by the astronauts? light-years
If astronauts could travel at v = 0.960c, we on Earth would say it takes (4.20 / 0.960) = 4.67 years to reach Alpha Centauri, 4.38 lightyears away. The astronauts disagree. (a) How much time passes on the astronauts' clocks? years (b) What is the distance to Alpha Centauri as measured by the astronauts? light-years
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...
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?
c. Remember that a light-year is defined as the distance, relative to Earth, that light travels in one calendar year on Earth. If Alpha Centauri is 4.37 light-years away from Earth, what is this distance measured by you from your spaceship? d. You and your twin decided to synchronize your clocks before you started your trip so you can compare the length of your trip once you get back. i. How long does it take the spaceship to reach its...
The nearest star to Earth besides the Sun is Proxima Centauri, which is a distance of approximately 4 light years away. A planet that may be able to sustain liquid water on its surface was discovered in 2016 orbiting Proxima Centauri. According to observers on Earth, a spaceship that travels at 0.9c should be able to reach the planet in 3.6 years. How long would the trip take according to astronauts on board the spaceship?
How much time does it take light to travel from the moon to the earth, a distance of 384000 km ? Correct answer= 1.28 secs Light from the star α Centaurus takes 4.30 years to reach the earth. What is the distance to α Centaurus in kilometers? please answer with 3 significant figures and km for units
You travel in ship 2) You travel in your ship White Star One at a constant speed of v 0.96*c to the nearby star Proxima Centauri, located 4.2 light years away from Earth. a. From your point of view in the ship, how far is the star from the Earth? b. If your mass is 68 kg, what is your kinetic energy while moving with the ship? c. How long does the journey take, according to clocks on your ship?...
The nearest star to Earth is Proxima Centauri, 4.2 light-years away. Part A At what constant velocity must a spacecraft travel from Earth if it is to reach the star in 3.9 years, as measured by travelers on the spacecraft? Express your answer using two significant figures. v=_____c Part B How long does the trip take according to Earth observers? Express your answer using two significant figures. t=_____ years
