A tissue cross-section viewed on a microscope slide shows a cell of almost rectangular shape with dimensions 6.9 × 10-4 cm by 1.

zimovet [89]

Answer:

The cross-sectional area is $A = 7.59 *10^{-11} \ m^2$

Explanation:

From the question we are told that

The dimension of the cell is 6.9 × 10-4 cm by 1.1 × 10-3 cm = $6.9*10^{-6} \ m \ by\ 1.1*10^{-5} \ m$

Generally the cross-sectional area is mathematically represented as

$A = 6.9*10^{-6} * 1.1*10^{-5}$

=> $A = 7.59 *10^{-11} \ m^2$

A polarized light that has an intensity I0 = 60.0 W/m² is incident on three polarizing disks whose planes are parallel and cente

nikitadnepr [17]

Answer:

The transmitted intensity through all polarizers is $I_3 =41.31 W/m^2$

Explanation:

According to Malu's law the intensity of a polarized light having an initial intensity $I_0$ is mathematically represented as

$I = I_0cos^2 \theta$

Now considering the polarizer(The polarizing disk) the equation above becomes

$I = I_0 (cos^2 \theta)^n$

Where n is the number of polarizers

Substituting $60.0W/m^2$ for the initial intensity 3 for the n and 20° for the angle of rotation

$I_3 = 60 (cos^220)^3$

$=41.31 W/m^2$
