Select True or False for the following statements about conductors in electrostatic equilibrium. All points of a conductor are a

t the same potential. Charges prefer to be uniformly distributed throughout the volume of a conductor. The electric field inside the conducting material is always zero. Just outside the surface of a conductor, the electric field is always zero.

Unpolarized light whose intensity is 1.46 W/m2 is incident on the polarizer in the drawing. (a) What is the intensity of the lig
Serhud [2]

Answer:

0.73 W/m²

0.2522 W/m²

Explanation:

I_0 = Unpolarized light = 1.46 W/m²

\theta = Analyzer angle = 54°

Light through first filter

I_1=\frac{I_0}{2}\\\Rightarrow I_1=\frac{1.46}{2}\\\Rightarrow I_1=0.73\ W/m^2

The intensity of the light leaving the polarizer is 0.73 W/m²

After passing through analyzer

I=I_1cos^2\theta\\\Rightarrow I=0.73\times cos^2(54)\\\Rightarrow I=0.2522\ W/m^2

The intensity of the light that reaches the photocell is 0.2522 W/m²

If the speed of light in air is 3.00 times 10 to the 8 m/s power and the speed of light in water is 2.25 times 10 to the 8 power
kykrilka [37]
The refractive index is essentially the speed of light through a vacuum (extremely similar to air) divided by the speed of light through given medium.
I also attached some of my physics notes on refraction and that sort of jazz as they may help :)

In the formula for magnetic deflection, FM is equal to qvB. Match each symbol in this formula with what it represents.
slava [35]

Answer:

1.F_m-Deflection force

2.q-Charge

3.v-Velocity of the charge

4.B-Perpendicular magnetic field strength

Explanation:

We are given that magnetic  deflection

F_m=qvB

We have to match each symbol in formula with what it  represents.

In this formula

F_m=Deflection force

q=Charge of particle

v=Velocity of charge

B=Perpendicular magnetic field strength

Therefore,

1.F_m-Deflection force

2.q-Charge

3.v-Velocity of the charge

4.B-Perpendicular magnetic field strength
