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.

Units...Nothing is accurate without UNITS. 8.0±0.3 lbs,? Newtons? 3.5±0.2 m²? ft²? cm²? km²? furlong²? fathoms²?
your answer will be 8.0±0.3 / 3.5±0.2 units / units²
made from pure metals . . . no;
they've been made from all kinds of weird compounds and alloys.
conduct electricity with zero resistance . . . yes;
that's why they're called "superconductors".
produce a strong magnetic field . . . possible, but not because it's a superconductor;
just like any other conductor, the magnetic field depends on the current that's flowing in the conductor.
no loss of energy in the transfer of electricity . . .
there's no loss of energy in the current flowing in the superconductor;
but if you tried to transfer the current out of the superconductor into
something else, then there would be some loss.
