Unpolarized light is incident upon two ideal polarizing filters that do not have their transmission axes aligned. If 14% of the

vladimir1956 [14]

Answer:

A) 58 degree

Explanation:

When unpolarized light passing through first polarizer then the intensity of light becomes half as it will get polarized

So let say the intensity of unpolarized light is "Io" then after passing through first polarizer the intensity will become half

Now when this polarized light passing through another polarizer then the intensity of light is given by Malus law

As per Malus law if the angle between two polarizer axis is inclined at some angle

then it is given as

$I = I_0 cos^2\theta$

$0.14I_0 = 0.5I_0cos^2\theta$

$0.28 = cos^2\theta$

$\theta = 58 degree$

State coulomb's law mathematically

Vsevolod [243]

Coulomb's law is express as:

$\begin{gathered} F=k\frac{q_1q_2}{r^2} \\ \text{ where} \\ k\text{ is Coulomb's constant} \\ q_1\text{ and }q_2\text{ are the charges} \\ r\text{ is the distance between charges} \end{gathered}$

Evaluate ( 64800 ms ) 2 to three significant figures and express the answer in Si units. Express your answer using three signifi

Sergeu [11.5K]

Answer:

42.0×10² second²

Explanation:

Here, time is given in milisecond

(64800 ms)²

= 4199040000 ms²

The SI unit is seconds

1 second = 1000 milisecond

$1\ milisecond=\frac{1}{1000}\ second$

$\\\Rightarrow 1\ milisecond^2=\left(\frac{1}{1000}\right)^2\ second^2$

$4199040000\ ms^2=4199040000\times \left(\frac{1}{1000}\right)^2\ second^2=4199.04\ second^2$

42.0×10² second²
