Unpolarized light with intensity s is incident on a series of polarizing sheets. the first sheet has its transmission axis oriented at 0°. a second polarizer has its transmission axis oriented at 45° and a third polarizer oriented with its axis at 90°. determine the fraction of light intensity exiting the third sheet with and without the second sheet present.

hey , the answer is c

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
