boyakko [2]
Autotrophs remove CARBON DIOXIDE from the air and fix this into tissues providing OXYGEN for secondary consumers.

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
Radda [10]

Answer:

180seconds

Explanation:

According to the question, Kepler-186f is an exoplanet that orbits a star called kepler-186, other than the Sun.

Distance of the star (kepler-186) away from the planet is 5.4 x 10^10 meters

In order to calculate how long i.e. time, a light moving at an average speed of 3.0 x 10^8 m/s will get to the exoplanet from the star, we use;

Speed (m/s) = Distance (m) ÷ time (s)

Time = Distance/speed

Time = 5.4 x 10^10 ÷ 3.0 x 10^8

Time = 5.4/3.0 × 10^ (10-8)

Time = 1.8 × 10^2

Time = 180seconds.
