A great amount of Antarctic animals feed on them. Whales, penguins, fish, birds, etc. They eat phytoplankton.
The time taken by light to reach pluto will be 5.6 hours.
<h3><u>Explanation</u>:</h3>
The light is a electromagnetic wave that has the highest velocity and same velocity as all other electromagnetic radiations existing in this universe. The light takes about 8.2 seconds to reach from sun to earth. So lets check howmuch time does light take to reach pluto from sun.
The speed of light was calculated to be
m/s. This is the speed of each and every electromagnetic waves.
The distance of pluto from sun is huge. On an average it's
km or
m.
So time taken by light to reach from sun to pluto will be
seconds. Or actually 5.6 hours.
The correct answer is be sure that your instrument is calibrated properly. If your instrument isn't calibrated, then your data will be inconsistent.
