The speed of light in space — the ultimate speed limit of the Universe — is 9.45 x 10^12 km/yr. What fraction of the speed of light is your interstellar travel velocity from 3.19 x 10^8 km/yr. Show work and give the answer as a decimal

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

Dao makes a table to identify the variables used in the equations for centripetal acceleration. what quantities belong in cells x and y?

What conclusion can be made based on the temperature of soil when the light hits the soil at 0°, 45°, and 90° angles in section 2 of the experiment? did your results support your hypothesis? why or why not?
