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

<h3>What is Human Capital?</h3>
The term human capital is defined as the economic value of a worker's experience and skills.

Answer:
Roll a pair of dice for both of them to have 2 dots to get 4. To get 11 you must have one die to get 5 dots and the other to get 6 dots.
Explanation:
The amount of pure alcohol that the pharmacist must add to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution is; 20 cm³
<h3>Volume of Solutions</h3>
Let x represent the volume of 100% pure alcohol in cm³ that is required to be added. Thus;
x(100%) + 10%(10 cm³) = 70%(x + 10 cm³)
Multiplying out the bracket gives;
x + (10 × 0.1) = 0.7(x + 10)
⇒ x + 1 = 0.7x + 7
x - 0.7x = 7 - 1
0.3x = 6
x = 6/0.3
x = 20 cm³
In conclusion. the volume of pure alcohol required to be added to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution is 20 cm³
The complete question is;
How much pure alcohol must a pharmacist add to 10 cm of a 10% alcohol solution to strengthen it to a 70% solution? ASAP
