Technician A says that a wrong tire size installed on a vehicle can set a fault code in the electronic brake control module. Technician B says that you should use service information to determine how to diagnose the problems and locate the cause of faults in the electronic brake control system. Who is correct?a. Tech Ab. Tech Bc. Both A and Bd. Neither A nor B

Both

Explanation:

They are both right. The first technician who said wrong tire size installed on a vehicle can set a fault code in the electronic brake control module was right. Because the size might alter the alignment of the vehicle, hence triggers the censor. He probably spoke from experience. The other technician who stated otherwise knew such fault code might have risen as a result of something else, so using the service information will give the precise diagnosis.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
