Tech a says that most wheels have a drop center or deep well that is used in installing a tire on the wheel. tech b says that the drop center or deep well is used to prevent the tire from coming off the wheel in the case of low tire pressure. who is correct?

Both Technician A and B

Explanation:

The drop center or deep well allow for easy installation of tyre on the wheel when the tyre have same inner diameter as the wheel's outer diameter, one side of the tire must be placed into this depression on the wheel so that the tire can slide over just enough to let the other side of the tire slip over the rim edge. It also function to prevent the tyre from coming off the tyre in case of blown off or low tyre pressure.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).
