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 = 2.35 * 10^-18 J

n = number of photons = ?

h = Planks constant = 6.6 * 10^-34 Js

c = speed of light = 3 * 10^8 m/s

λ = 510 * 10^-9 m

Making number of photons the subject of the formula;

n =2.35 * 10^-18 *  510 * 10^-9 / 6.6 * 10^-34 * 3 * 10^8

n = 6 photons

Let see if you know long division 3) 461​
WARRIOR [948]

Answer:

461 = dividend

3 = divisor

Explanation:

Step 1:

Start by setting it up with the divisor 3 on the left side and the dividend 461 on the right side like this:

           

   3 ⟌ 4 6 1

Step 2:

The divisor (3) goes into the first digit of the dividend (4), 1 time(s). Therefore, put 1 on top:

       1    

   3 ⟌ 4 6 1

Step 3:

Multiply the divisor by the result in the previous step (3 x 1 = 3) and write that answer below the dividend.

       1    

   3 ⟌ 4 6 1

      3    

Step 4:

Subtract the result in the previous step from the first digit of the dividend (4 - 3 = 1) and write the answer below.

       1    

   3 ⟌ 4 6 1

     - 3    

       1    

Step 5:

Move down the 2nd digit of the dividend (6) like this:

       1    

   3 ⟌ 4 6 1

     - 3    

       1 6  

Step 6:

The divisor (3) goes into the bottom number (16), 5 time(s). Therefore, put 5 on top:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

Step 7:

Multiply the divisor by the result in the previous step (3 x 5 = 15) and write that answer at the bottom:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

       1 5  

Step 8:

Subtract the result in the previous step from the number written above it. (16 - 15 = 1) and write the answer at the bottom.

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1  

Step 9:

Move down the last digit of the dividend (1) like this:

       1 5  

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

Step 10:

The divisor (3) goes into the bottom number (11), 3 time(s). Therefore put 3 on top:

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

Step 11:

Multiply the divisor by the result in the previous step (3 x 3 = 9) and write the answer at the bottom:

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

           9

Step 12:

Subtract the result in the previous step from the number written above it. (11 - 9 = 2) and write the answer at the bottom.

       1 5 3

   3 ⟌ 4 6 1

     - 3    

       1 6  

     - 1 5  

         1 1

     -     9

           2

You are done, because there are no more digits to move down from the dividend.

The answer is the top number and the remainder is the bottom number.

Therefore, the answer to 461 divided by 3 calculated using Long Division is:

153

What evidence from the text best supports the theme that women have an equal right to be free? ""He is legally freed from all ob
lesya692 [45]

Answer:

The right answer is: "There must be a perfect freedom on both sides". beyond the mere symbolism that represents the delivery of a ring, it is assumed in this context that the woman will also enjoy the emancipation that the marriage dissolution represents. In such a way that the independence of the woman must be the same -or even bigger- than the man.
