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.
2) Cross-fertilization makes for more variation in the traits of plants, giving them immunities and resistances to weather, pests, and disease.
D. A struggle for existence is apparent.
If a struggle for existence is apparent, natural selection occurs because all of the weak/unfit/unadapted ones die.
It would likely be cold...
Maybe 40 or 30 degrees?
