7. Kepler-186f is an exoplanet that orbits a star other than the Sun. Its star is the red dwarf Kepler-186. It is the first planet to be discovered that orbits its star at a distance similar to Earth's distance from the Sun.
If Kepler-186f is approximately 5.4 x 10^10meters from Kepler-186, how long does it take for light from
the star to reach the exoplanet? The speed of light is 3.0 x 10^8 m/s.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
