Answer:
Technician B is correct
Explanation:
An oxygen sensor will generate about 1.0 volts when the fuel mixture is rich and there is little unburned oxygen in the exhaust. When the mixture is lean, the sensor's output voltage will drop down to about 0.1 volts.
An o2 sensor cannot accurately measure how rich or how well an exhaust system is.
Therefore, Technician B is correct.
Answer:
1.52 m
Explanation:
We are given that
Maximum force=F=679 N
Mass of rock ,m=385 kg
Distance,d=0.233 m
We have to find the minimum total length L of the rod required to move the rock.
Torque on rock=
Where 
Torque on man=
Hence, the minimum total length of rod=1.52 m
3 is B my dude and the reason nobody answered is because thousands of questions are asked every day. So not every question can be answered. It doesn't have to do with being lazy.
Answer:
Hope this helps! Mark as brainliest if liked thanks!
Explanation:
Your reasoning that the shadow is the shortest at mid-day is spot-on!
The wording of the question is the key to the answer. It says that the measurements were made in Summer. So this means that British Summer Time (BST) is being applied. BST is one hour ahead of Greenwich Mean Time and so what looks like 1pm is really 12 noon.
The safest sort of answer is to say that the shadow is shortest when the sun is at its highest point, and in this particular question that is at 1 pm because it is BST.
