Answer:
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
D=m/v. (Density equals mass over volume).
So in your case density = 4.2/6
Which equals 0.7
Your units will be grams over milliliters
So your answer is 0.7 g/ml
Answer:
5.00×10-19 J
Explanation:
E = hv
but v = c ÷ wavelength
E = (6.626×10-34) × ((3×10^8)÷(398×10-9))
= 4.9945×10-19
≈5.00×10-19
Hope this helps
