A vehicles engine temperature gauge is reading higher than normal and the radiator fan does not operate. Technician A says that no continuity across the fan motor could be the cause. Technician B says that an open radiator fan fuse could be the cause. Who is correct?

Both technicians are right

Explanation:

It is known that the vehicle's engine temperature gauge is reading higher than normal and the radiator fan does not operate.

The higher temperature readings suggests that the radiator fan is not working due to its motor not being operating. This is confirmed by the technician A since he checked the continuity of the fan motor and it was discontinued.

On the other hand, Technician B suggests that the fuse of the radiator fan might be open which may have caused the discontinuity of the fan motor.

Both problems point out towards the same result. Therefore, both technicians are right.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
