The minimum number of photons of green light that can be detected by the human eye is 6.
Given that;
E = nhc/λ
E = energy of the photon = 
J
n = number of photons = ?
h = Planks constant = 
Js
c = speed of light = 
m/s
λ = 
m
Making number of photons the subject of the formula;
n =
n = 6 photons

Answer:
Explanation:
1) Reduce the 
to 
by dividing with 3. (12/3 = 4 & 15/3 = 5)
×
2) Raise the numerator and denominator to the power.
5×5= 25 & 6×6=36
×
3) Reduce the numbers (25 & 5) with the greatest common factor 5
× 
4) Multiply the fractions.
5×4= 20
36×1= 36
5) Simplify.
20÷4 = 5
36÷4 = 9

Since Goodman is unresponsive, Valerie shall check for breathing and a pulse simultaneously for no more than <u>10 seconds</u>.
<h3>What is cardiac cycle?</h3>
Cardiac cycle is a process that involves the complete heartbeat of the human heart, which comprises sequential alternating contraction and relaxation of the atria and ventricles, so as to cause blood to only flow in one direction throughout the human body and aid respiration (breathing).
As a general rule, Valerie shall check for breathing and a pulse simultaneously for for at least 5 seconds, but shouldn't be more than <u>10 seconds</u>.

Answer:
x=3
Explanation:
-the bisector line has to go trough the point with coordinates (3,4), see picture
-the line perpendicular and at that point (3,4) is a vertical line with the equation x=3
do 230/4 you will get 57.5 and then you do 57.5 x 16 you get 920
if it is multiple choice answer then please tell me if that choice is there
