Technician a says that an oxygen sensor can have one, two, three, four, or more wires, depending on the style and design. technician b says that if the exhaust has little oxygen, the voltage of the oxygen sensor will be close to 1 volt (1000 mv) and close to zero if there is high oxygen content in the exhaust.
who is right?

a) technician a only
b) technician b only
c) both technicians
d) neither technician

Imagine an isolated positive point charge q (many times larger than the charge on a single proton). there is a charged particle a (whose charge is much smaller than charge q) at a distance from the point charge q. on which of the following quantities does the magnitude of the electric field created by charge q at particle a's position depend? check all that apply. the type of the charge on the charged particle athe relative orientation between q and a (while the distance between q and a is fixed)the specific location of the charged particle a (while the distance between q and a is fixed)the amount of the charge on the point charge qthe specific location of the point charge q (while the distance between q and a is fixed)the distance between the point charge q and the charged particle athe amount of the charge on the charged particle a
