Answer:
100nm-280nm
Explanation:
Ultraviolet rays (UV) are part of the electromagnetic spectrum. It goes from 10nm to 400nm wavelengths, they are shorter than visible light, thus it's impossible to see by a human eye, and larger than X-rays (used in many medical applications and harmful when long-exposed).
According to its wavelengths, UV can be divided in different types:
UVA: long wave UV (315nm-400nm)
UVB: medium-wave UV (280nm-315nm)
UVC: short wave UV (100nm-280nm)
Therefore, UVC comprises wavelengths between 10nm and 280nm.
Answer:
Sunlight
Explanation:
Sunlight is necessary in photosynthesis, which provides the main form of energy that plants use, glucose. Water (H2O) is also important because it forms part of glucose and is necessary in the process.
Answer:
a
Explanation:
because your getting energy from the sun
<u>Answer</u>
(g²n - m)/(gm)
<u>Explanation</u>
g - m ÷ gn = g - m/gn
Make the equation have the same denominator
g - m ÷ gn = g - m/gn = (ggn)/gn - m/gn
= (g²n)/gn - m/gm
Since they have the same denominator, we can carry out the subtraction on the numerator and then put them under one denominator.
(g²n)/gn - m/gm = (g²n - m)/(gm)
Helps living things survive cuz they need water just like humans
