Answer:
Explanation:
Given
Initial Intensity of light is S
when an un-polarized light is Passed through a Polarizer then its intensity reduced to half.
When it is passed through a second Polarizer with its transmission axis
here
When it is passed through third Polarizer with its axis to first but to second thus
When middle sheet is absent then Final Intensity will be zero

Answer:
When the different ions cross the neuron membrane due to this an action potential generated
Explanation:
When the different ions cross the neuron membrane due to this an action potential generated.
The steps for action potential
1. Depolarization .When positively charge sodium ions enters in to the nerve cell.This is also known as upswing.
2. Repolarization
3. Refractory Phase
So the answer is "When the different ions cross the neuron membrane".
The electric flux is - 4.80 × 10∧5 N m2 C-1
How to calculate the electric flux
Use the formula:
Electric flux, ΦE = EScosθ
Where,
E = electric flux
S = area of the rectangular surface = length × breadth = 6.00 × 3.00 = 18.00 m²
E = magnitude = 2. 70 × 10∧4 N/C
θ = the angle between the electric field lines = 15. 7°
Substitute the values into the equation
EФ = 2. 70 × 10∧4 × 18. 00 × Cos (15.7)
EФ = 2. 70 × 10∧4 × 18. 00 × -0.9999
EФ= - 4.79 × 10∧5 N m2 C-1
Therefore, the electric flux is - 4.80 × 10∧5 N m2 C-1

So you know the speed of a wave, and speed is how much the wave moves per second. This wave travels 3x10^8 meters per second. So to find how for you traveled you need to know how many seconds the wave traveled for, 20 minutes is equal to 1200 seconds (times 20 minutes by 60). Then times the seconds by the speed (3x10^8 m/s)x(1200 s) = 3.6x10^11 meters
