A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 x 10^8m/s) 5 light-minutes 6 light-days 6 light-days, but this time answer in miles (enter just the number with no units)

A light-year is the distance that light can travel in one year. Similarly, we can define a light-second, light-day, etc. as the distance that light can travel in other time intervals. Calculate the distance represented by each of the following: (Assume that the speed of light is 3 × 108 m/s). 1. 4 light-seconds 2. 3 light-minutes 3. 2 light-days 4. 2 light-days, but this time answer in miles (enter just the number with no units)
A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 km. 1 year = 3.156 ×× 107 s. How many meters are there in 1.70 ly? Express your answer using three significant figures. Express in scientific notation! 1.70 ly = _________________m How many AU are there in 1.70 ly light-year? Express your answer using three significant figures. Express in scientific notation! 1.70 ly = _________________AU

Several hundred years in the future, humans discover an alien world named Noveria. On Noveria, time is measured in pjokas, which is equivalent to 5.93 seconds, There are 7 pjok in every pjokas (much like there are 60 seconds in a minute). If a Noverian alien watches 40 mok of cat videos, how many minutes is this?
