Answer:
Time taken by space shuttle = 714.28 m/s
Explanation:
Given:
Distance cover by space shuttle = 500,000 meter
Speed of space shuttle = 700 m/s
Find:
Time taken by space shuttle
Computation:
Time taken = Distance / Speed
Time taken by space shuttle = Distance cover by space shuttle / Speed of space shuttle
Time taken by space shuttle = 500,000 / 700
Time taken by space shuttle = 714.28 m/s
Dust in the atmosphere represents suspension. It is collaborating shaped during colliding and collapsing of the interstellar mediums this is influenced by the gravitational attraction of the atoms and particles in the entitles. Hence, there are three types of nebular namely, are classical nebula, diffuse nebula, planetary nebular and supernova remnants.
