They can not guarantee as much functionaluty when compared to OEMs. Original Equipment Manufacturer (OEM) usually their own proprietary scan tools which offer better and functionality to service their special line of vehicles. So Technician A alone is correct.
Answer:
work done by electric field is 0.06 J
Explanation:
Given data:
Two point charge is 
0+1 charge positioned is (0 cm , 1 cm, 0.00 cm)
-1 charge positioned is (0 cm , -1 cm, 0.00 cm)
E = 3.0\times 10^6 N/C
From above information, the distance between given two charges d = 2 cm
then d = 0.02m
work needed is W = q E d

W = 0.06 J
Therefore work done by electric field is 0.06 J
Answer:
a) 1 / 3 N
b) 5/3 m/s
Explanation:
For constant speed V at the interface of the two fluids the net force is zero.
Hence, F top = F bottom thus the shear stresses at top and bottom must be the same.

For force of top plate
