An unpolarized beam of light with an intensity of 4000 W/m2 is incident on two ideal polarizing sheets. If the angle between the

erastova [34]

Answer:

The intensity is $I_2 = 1654 \ W/m^2$

Explanation:

From the question we are told that

The intensity of the unpolarized light is $I_o = 4000 \ W/m^2$

The angle between the ideal polarizing sheet is $\theta = 0.429 \ rad = 0.429 * 57.296 = 24.58^o$

Generally the intensity of light emerging from the first polarizer is mathematically represented as

$I_2 = \frac{I_o}{2}$

substituting values

$I_1 = \frac{4000}{2}$

$I_1 = 2000 \ W/m^2$

Then the intensity of incident light emerging from the second polarizer is mathematically represented by Malus law as

$I_2 = I_1 cos^2 (\theta )$

substituting values

$I_2 = 2000 * [cos (24.58)]^2$

$I_2 = 1654 \ W/m^2$

LekaFEV [45]

Answer:

The actual t statistic is -1.34.

Explanation:

In statistics, the t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error. It is used in hypothesis testing.

Pearson's correlation is utilized when you have two quantitative variables and you wish to see if there is a linear relationship between those variables. Your research hypothesis would represent that by stating that one score affects the other in a certain way. The correlation is affected by the size and sign of the r.
