Homework Statement I have a question regarding calculating luminosity given accretion power. I have accretion power given to me as Δm/Δt= 1.5 solar masses/yr, in order to solve for luminosity are we supposed to convert the accretion power into solar masses/seconds or is it just some kind of...

the answer for tmoving is 5.6 and when you add that to the age of the passenger that is 21yrs+ 5.6 yrs= 26.6 yrs old when the ship arrives at Altair!

thank you I understand it now, so Lmoving = 20m and Lrest= 100 meters and then I just solve for velocity. Thanks for all the help!

Homework Statement The dimensions of your friend’s spaceship are 100 meters in length, with a cabin width of 20 meters (i.e., you could approximate the main body of the ship as a cylinder with length 100 meters and diameter 20 meters). However, since your friend’s spaceship is speeding past...

okay, I understand how to do it, so I plug what I calculated into the time dilation equation as delta t rest and calculate tmoving based on what I have given. Thank you!

Special relativity homework question time dilation 1. Homework Statement You are a passenger on a brand-new spaceship that travels at 95% of the speed of light, i.e., v = 0.95 × c. The spaceship is bound for the star, Altair, at a distance of 17 light years from Earth. If the spaceship...

Homework Statement You are a passenger on a brand-new spaceship that travels at 95% of the speed of light, i.e., v = 0.95 × c. The spaceship is bound for the star, Altair, at a distance of 17 light years from Earth. If the spaceship departs on your 21st birthday, at a speed of v = 0.95c, how...
