(a) A light-year, the distance light travels in 1 year, is a unit used by astronomers to measure the great distances between stars. Calculate the distance, in miles, represented by 1 light-year. Assume that the length of a year is 365.25 days, and that light travels at a rate of 3.00 × 10⁸ m/s.

(b) The distance to the nearest star (other than the Sun) is 4.36 light-years. How many meters is this? Express the result in scientific notation and with all the zeros.
