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:
tangent of angle I =
/
) or 
Explanation:
tangent = opposite/adjacent
we need to solve for the opposite side, using pythagorean theorem
(
)^2 + b^2 = 9^2
59 + b^2 = 81
b^2 = 22
b = 
tangent = opposite/adjacent

We have that force forces on a plane we Resolve to the x plane and the y plane then we derive the <em>corresponding</em> result using the equation

From the question we are told
The following forces are applied to a box.
What is the net force acting on the box?.
<h3>
Force</h3>
Net force is seen as the Difference between the force coming to and out of a <u>body</u>
Generally the equation for the Net Force is mathematically given as

Therefore
For two forces
- We Resolve to the x plane and the y plane then we derive the corresponding <em>result</em> using the equation
