What can we say about a polarizing filter with vertically aligned chemical molecules?
A
It will allow vertically polarized light to pass through it.
It will allow horizontally polarized light to pass through it.
B.
C.
It will block unpolarized light.
D.
It will allow all light to pass through it unchanged.

A . It will allow vertically polarized light to pass through it.

Explanation:

Polarization is the attribute in which waves oscillate in a particular direction relative to the direction of travel. The direction of polarization determines the type of polarized light produced. Since the chemical molecules are vertically aligned, it will only allow vertically polarized light pass through it.

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
