Place the four steps in order to explain how an electric motor works. 1.A loop of wire is placed between the poles of a permanent magnet. The wire is attached to a commutator. Current runs through the electromagnet. 2.The direction of the current switches, causing the poles to switch and causing the magnetic field to reverse. 3.Electromagnetic forces, caused by the interaction of the electromagnet and permanent magnet, cause the electromagnet to rotate. 4.The electromagnet continues to rotate, causing the direction of the current to continue to change while the wire turns.

Listen base your answer to the question on the information below.propane is a fuel that is sold in rigid, pressurized cylinders. most of the propane in a cylinder is liquid, with gas in the space above the liquid level. when propane is released from the cylinder, the propane leaves the cylinder as a gas. propane gas is used as a fuel by mixing it with oxygen in the air and igniting the mixture, as represented by the balanced equation below.c3h8(g) + 5o2(g) → 3co2(g) + 4h2o() + 2219.2 kja small amount of methanethiol, which has a distinct odor, is added to the propane to consumers detect a propane leak. in methanethiol, the odor is caused by the thiol functional group (–sh). methanethiol, ch3sh, has a structure that is very similar to the structure of methanol.what is the correct structural formula for a molecule of methanethiol
