Answer:

1.171

Explanation:

if n₁sinΘ₁=n₂sinΘ₂, then n₂=n₁sinΘ₁ / sinΘ₂;

$n_2=\frac{1.5*sin45}{sin65}=\frac{1.5*0.707}{0.906} =1.1705$

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

$I = I_0 cos^2\theta$

$0.14I_0 = 0.5I_0cos^2\theta$

$0.28 = cos^2\theta$

$\theta = 58 degree$

Represent 7468 N with SI units having an appropriate prefix. Express your answer to four significant figures and include the app

Musya8 [376]

Answer:

7.468 kN

Explanation:

Here the force is given in Newton

Some of the prefixes of the SI units are

kilo = 10³

Mega = 10⁶

Giga = 10⁹

Tera = 10¹²

The number is 7468.0

Here, the only solution where the number of significant figures is kilo. If any other prefix is chosen then the significant figures will increase.

1 kilonewton = 1000 Newton

$1\ Newton=\frac{1}{1000}\ kilonewton$

$\\\Rightarrow 7468\ Newton=\frac{7468}{1000}\ kilonewton\\ =7.468\ kilonewton$

So, 7468 N = 7.468 kN
