1.34 light-years to miles (a light-year is an astronomical measure of the distance traveled by light in a year, or 365 days; the speed of light is 2.998 × 10^8 m ;1 km = 0.6125 mi) Part 2 of 3 mi Be sure your answer has the correct number of significant digits. 30.0 yd to centimeters (1 in = 2.54 cm) 2743.2 cm Part 3 of 3 Be sure your answer has the correct number of significant digits. 3.4×1010 cm S to ft X S (1 in = 2.54 cm)
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.

- The distance from the Sun to the nearest star is about 4 1016 m. The Milky Way galaxy (Fig. P1.31) is roughly a disk of diameter 1021 in and thickness 1019 m. Find the order of magnitude of the number of stars in the Milky Way. Assume the distance between the Sun and our nearest neighbor is typical. Figure P1.31 The Milky Way galaxy.arrow_forwardThe meter was redefined as a reference to Earth, then to krypton, and finally to the speed of light. Why do you think the reference point for a meter continued to change?arrow_forwardThe speed of light is 2.998 × 108 m/s. One light-year is the distance that light travels in one year. One Astronomical Unit (AU) is 1.50 × 108 km. (a) How many meters are in 1.0 light-year? (b) How many meters are in 1.000 light-year? (c) How many AU are in 1.00 light-year?

- How many miles does light travel in one hour? The speed of light is 1.86x10^5 miles per second.arrow_forwardThe speed of light in a vacuum is 2.998×10^8 m/s. What is its speed in kilometers per hour (km/h)? What is its speed in miles per minute (mi/min)?arrow_forwardA 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)arrow_forward
