Answer to Question #81634 in Physics for Ha
Question #81634
The light from a star takes 21⁄2 years to reach an observer. If the velocity of light is 330 × 106 ms-1, determine the distance of the star from the observer based on a 365 day year.
Expert's answer
The distance of the star from the observer:
l=vt
l=(330 ∙ 〖10〗^6 )(21/2(365)(24)(3600))=1.1∙ 〖10〗^17 m
l=vt
l=(330 ∙ 〖10〗^6 )(21/2(365)(24)(3600))=1.1∙ 〖10〗^17 m
