One astronomical unit (AU) is equal to

Astronomical distances are so large compared to terrestrial ones that much larger units of length are used for easy comprehension of the relative distances of astronomical objects. An astronomical unit (AU) is equal to the average distance from Earth to the Sun, 1.50xx10^(8)km . A parsec (pc) is the distance at which 1 AU would subtend an angle of 1 second of arc. A light year (ly) is the distance that light, traveling through a vacuum with a speed of 3.00xx10^(5) km/s, would cover in 1 year. Express a light - year and a parsec in kilometers.

Define astronomical unit.

Define astronomical unit (A.U), write its value in metres.

What is the relation between 1 astronomical unit (AU) and one parsec (P)?

Suppose we invent a unit of mass which we shall call the caendish (C). One cavendish of mass is defined such that G = 1.0000(AU)^(3)//(yr^(2)C) . Our unit of length is the astronomical unit (AU) , the earth-sun distance -1AU = 1.496 xx 10^(11) m - and our unit of time is the year (yr) . (a) Datermine the conversion factor between C and kg. (b) Find the mass of the sun in C.
