It’s approximated that tbelow are a trillion comets in the Oort cloud, which exhas a tendency out to around 50,000 AU.Part A What is the full volume of the Oort cloud, in cubic AU? (Hints: For the purpose of this calculation, you can assume the Oort cloud fills the whole sphere out to 50000 AU. The equation for the volume of a spbelow is 43πr3 wright here r is the radius.)VtheOortcloud = AU3Part BHow a lot area does each comet have in cubic AU, on average?Vper comet = AU3 Part CTake the cube root of the average volume per comet, to discover their typical spacing in AU.Ltypical = AU

You are watching: How much space does each comet have in cubic au, on average?

What is the full volume of the Oort cloud, in cubic ( m AU)? (Hints: For the purpose of this calculation, you have the right to assume the Oort cloud fills the totality sphere out to 50000 ( m AU). The equation for the volume of a sphere is (frac43pi r^3) wbelow r is the radius.)
Plug the numbers into the formula and also calculate: 4/3 pi r^3 = 4/3 pi (5x10^4)^3 = 5.24 x 10^14 cubic AU
