Answer:

0.73 W/m²

0.2522 W/m²

Explanation:

I_0 = Unpolarized light = 1.46 W/m²

\theta = Analyzer angle = 54°

Light through first filter

I_1=\frac{I_0}{2}\\\Rightarrow I_1=\frac{1.46}{2}\\\Rightarrow I_1=0.73\ W/m^2

The intensity of the light leaving the polarizer is 0.73 W/m²

After passing through analyzer

I=I_1cos^2\theta\\\Rightarrow I=0.73\times cos^2(54)\\\Rightarrow I=0.2522\ W/m^2

The intensity of the light that reaches the photocell is 0.2522 W/m²

How many possible combinations are there for the values of l and ml when n = 2?
Alexeev081 [22]

For n = 2, l will have two values 0,1

For l = 0, ml = 0

      l = 1, ml = -1,0,1

These are the possible combinations.

The n is the principal quantum number

l is the azimuthal quantum number

ml is the magnetic quantum number.

The formula to find the azimuthal quantum number is

            l = 0,1,2,3 .......n-1

If n = 2, the azimuthal quantum number,

            l = 0 , 1

Then, the ml can be found using the formula,

           ml = 2l +1

For l = 0 , ml = 2(0) + 1

                    = 1

Therefore, ml will have only one value, which is 0

For l =1 , ml = 2(1) + 1

                  = 3

Therefore, the ml will have three values, they are -1,0,1

A horse has a momentum of 25 kg*m/s and a velocity of 2.5 m/s. What is the horse mass?
Ne4ueva [31]
<h3>Answer:  10 kg</h3>

==================================================

Work Shown:

We have these variables

  • p = momentum = 25 kg*m/s
  • m = mass = unknown
  • v = velocity = 2.5 meters per second

Solving for the mass gets us...

p = m*v

25 = m*2.5

25/2.5 = m

10 = m

m = 10

The mass of the horse is 10 kg.
