Calculate the number of miles in a light-year, using 1.86 105 mi/s as the speed of light. (Hint: The number of seconds in a year, 365 days, will be useful.) Answer in mi/y
A light year (LY) is the distance that light travels in one year.
1 LY = 9.46x1015 m.
Suppose we have detected a planet that orbits a star that is 104 light
years away. How many millions of years would it take us to get there if
we used a modern rocket with a maximum speed of 20.0 km/s (about
45,000 mph)? Assume 3 sig figs.
Using a single dimensional equation, estimate the number of steps it would take a person with a step length of 2.65 ft to walk from the Earth to Alpha Centauri a distance of 4.37 light-years. The speed of light is 1.86282 x 105 miles/s. Number of Steps = Enter your answer in accordance to the question statement x 1017

How many cubic meters are contained in one cubic parsec?arrow_forwardRecall that Hubble’s Law is given by V=HR; this means that H has units of inverse seconds (1/sec). A convenient laboratory set of units is to give H in km per sec per megaparsec. A parsec is 3.26 light years and the speed of light is 3 X 105 km/sec. Use 3.156 X 107 sec/yr. The first data off the then new Hubble Space telescope suggested a value of H equal to 108 km per sec per megaparsec. What is H in inverse seconds? Hint divide by the number of km in a megaparsec.arrow_forward

But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.arrow_forwardA small light source located 1 mm in front of a 1-m2m2 opening illuminates a wall behind.
