Question

You are the science officer on a visit to a distant solar system. Prior to landing on a planet you measure its diameter to be 1.8 x 10' m and its rotation period to be 22.3 hours. You have previously determined that the planet orbits 2.2 x 1011 m from its star with a period of 417 earth days. Once on the surface you find that the free-fall acceleration is 12.2 m/s. Part A What is the mass of the planet? Express your answer with the appropriate units. μΑ ? mg = Value Units Submit Request Answer Part B What is the mass of the star? Express your answer with the appropriate units. НА ? mg = Value Units Submit Request Answer Provide Feedback

Answer 1

=) Daimeler 0:1.8x107m 3) Radices () : 0.9x107m =) time period 6) - 22.3 hao's => distance (31) = 2.axio'm (420m2 star) 3) time (6) - 417x qux3600 > Babaloose - 36028800 see =) free-fall acceelaficu () =) jaa misce? (i) are have: 8 R² :-) mass of planet (M) G = 6:67X70" G (19.2)(0.9x107) 6.67X10" 9.882 X1014 6.67 X10 - 3) mass of planet (m): as 7.48X10 kg

(!!) similay, El ehh -) mass of Slay(m) GE2 (u) (3.10%(2.2810")3 6.67x16") (36028800) 419.94 X1033 8.658x105x10" :) mass of staro) = 48.5X1029 =) (mass of star (m) = 4.85x10 4.85x10 30 key
