Astronomy 1 -Orbital period Apps BA WISER-University- R, Blackboard UMB- CS1 10: Introductio..UMass Boston G Grammarly or QUESTION 3 Two exoplanets orbit a star that has twice the mass of the Sun. Planet A orbits at a distance of 2 au while Planet B orbits at a distance of 1 au. What is Planet A's orbital period compared to Planet B's orbital period? a. V2 = 1.414 times longer b. 8 times longer times longer d.4 times longer O eV8-2.828 times longer QUESTION 4 Which device sends the fastest signal? a all are equally fast 0 b. a green laser O c. a radio transmitter O d, an x-ray machine O e. a photon gun QUESTION 5

Explanation / Answer

T = 2pi * sqrt(r^3/GM)

ra = 2 au

rb = 1au

Ta/Tb = 2pi*sqrt(2^3/GM) / 2pi*sqrt(1/GM)

Ta/Tb = sqrt(8) ( e option)
