The E(incident) for the first  polarizer is E(incident)=-76.1930384332

The E(incident) for the second  polarizer is E(incident)=12.340115991

<u>Explanation:</u>

<u>Solving the problem:</u>

<u>Given</u>

Transmitted data = 80 mW

First polarizer= 30 degree

Second polarizer= 60 degree

We have the formula,

E (transmitted) = E (incident)cos()

<u>1. Through the first polarizer</u>

E (transmitted) = E (incident)cos()

80=E(incident) cos(60 degree)     (according to law subtract the given degree with 90 degree).

Then,

E(incident)=E(transmitted) cos()

E(incident) =80×cos 60 degree

E(incident)=-76.1930384332

The E(incident) for the first  polarizer is E(incident)=-76.1930384332

<u>2. Through the first polarizer</u>

We have the formula,

E (transmitted) = E (incident)cos()

80=E(incident) cos(30 degree)     (according to law subtract the given degree with 90 degree).

Then,

E(incident)=E(transmitted) cos()

E(incident) =80×cos 30 degree

E(incident) =12.340115991

The E(incident) for the second  polarizer is E(incident)=12.340115991

A physics major is cooking breakfast when he notices that the frictional force between the steel spatula and the Teflon frying p
wel

Answer:

Normal force = 8.75 N

Explanation:

given,

frictional force between the steel spatula and the Teflon frying pan=0.350 N

coefficient of friction between material =0.04

normal force = ?

using formula,

Frictional force = coefficient of friction × normal force

normal\ force = \dfrac{Frictional\ force}{coefficient\ of\ friction}

normal\ force = \dfrac{0.350}{0.04}

Normal force = 8.75 N

An ice skater spins with an angular speed 2w with an angular speed
sveticcg [70]
Anwser

It decreases The factor of two.

Step by step explanation

If she spin at a angular speed of 2w, and an initial speed of fi, when she slows down she is only has a angular speed of W, meaning that decreased 2

PS the anwser above me is wrong because in the question it said she decree so I couldn’t have stayed the same.

Hope this helps!
