Agrowling sound is heard from the rear of a rear-wheel-drive vehicle during cornering only. technician a says that defective rear axle bearings may be the cause. technician b says that defective drive pinion bearings may be the cause. which technician is correct?
a) technician a only
b) technician b only
c) technician a and b

A. Technician A only

Explanation:

The defective rear axle bearings may be the cause of the growling sound heard from the rear of a rear-wheel-drive vehicle during cornering only.

c) up is the direction the magnetic force is acting on the charge.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
