Answer:
there is ZERO TRANSMISSION through the polarizer.
Explanation:
Given the data in the question;
waves was polarized in the x direction propagate towards an ideal polarizer whose axis is aligned with the y-axis.
so θ = 90° { aligned with the y-axis }
now, we know that for polarized light going at angle θ to the polarizer;
I = I₀ × cos²θ
Where I₀ is the intensity of unpolarized light.
I is the intensity after polarization.
so we substitute the value of θ
I = I₀ × cos²( 90° )
I = I₀ × 0
I = 0
Therefore, there is ZERO TRANSMISSION through the polarizer.
Answer:
A vector is a quantity that has both magnitude and direction .
I don't think it has a unity
The acceleration will triple as well
Answer:
Option B
Explanation:
The electrons flow from negative terminal of a battery to the positive terminal because as the charge of electron is negative, it will get repelled by the negative terminal of the battery
Conventional flow actually assumes that the current flows out of the positive terminal, through the circuit and into the negative terminal of the battery
It actually says that direction of flow of current is in opposite direction to the direction of flow of electrons
The direction of current will not change even a resistor is placed in the circuit and it generates a potential difference across the resistor
But the current tries to move in such a way in which there will be less resistance to the flow
