You need to use Planck's law:
E = h·υ = (h·c)/λ
Without making all the calculations, a fraction is bigger than another when the denominator is smaller. Therefore you need to find the smallest wavelength (λ) which is 450nm.
You could also be helped by colors: in order of decreasing energy, you have blue - green - yellow - red.
In any case, the correct answer is a).
answer -
its both so write this
The independent variables are the administration of the drug - the dosage and the timing. The dependent variable is the impact the drug has on cancer.
Answer:
To share a positive experience she had with a pen pal
Explanation:
Just read the story :)
Electric energy??? there isn't much information from the question but I can infer it's electricity.
0.4823 m/s
The initial velocity u1 of the ball=0
From the law of conservation of linear momentum.
m1u1+m2u2=m1v1+m2v2
(160×0)+(170×u1)=(160×0.3)+(170×0.2)
u1=0.4823m/s
