When the computer receives a rich signal (high voltage) from the O2 sensor, it leans the fuel mixture to reduce the sensor's reading. When the O2 sensor reading goes lean (low voltage), the computer reverses again making the fuel mixture go rich.
Chemistry and physics are branches of science that both study matter. The difference between the two lies in their scope and approach. Chemists and physicists are trained differently, and they have different professional roles, even when working in a team.
The realm of atomic and nuclear physics. Nuclear physics is the field of physics that studies the building blocks and interactions of atomic. nuclei. Atomic physics (or atom physics) is the field of physics that studies atoms as an isolated system of. electrons and an atomic nucleus. It is primarily concerned with the arrangement of electrons around.
