Paul is driving his car on a sunny afternoon. which glasses should he ideally wear while driving?

Polarized sunglasses

Explanation:

Polarized sunglasses are comprised of polarized lenses which have a special  type of filter that can block the strong reflected light emitted from the sun. It also helps in decreasing the beam of light and eventually reduces the discomfort during the bright sunlight. It reduces the eye strain to see the objects clearly and visibly.

These sunglasses are mostly used while driving and protects our eyes from the harmful incoming solar lights and enables a person to observe the path clearly without any disturbance.

magnitude and direction

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
