The mean distance between the earth and the moon is 3.84x10^8 m, and the moon has an orbital period of 27.3 days. Find the distance from Earth of an artificial satellite that has an orbital period of 8.5 days. a. 1.76x10^8 m b. 1.76x10^4 m c. 1.76x10^10 m d. 5.24x10^8 m So far I got: I used the formula: (Ta/Tb)^2 = (rA/rB)^3 Plugged in these values: Ta= 8.5 days Tb= 27.3 days rA= ? rB= 3.84x10^8 m rA^3=(3.84x10^8)^3(8.5/27.3)^2 =(5.489164304x10^24)^1/3 rA^3=1.829721435x10^24 This obviously is incorrect. Please help thanx!
