The left side of the armature in an electric motor is pushed down. When the current changes direction, how is the motion of the armature affected? It is pulled up on the left side. It is pulled up on the right side. It is pulled toward the commutator. It is pushed away from the commutator.

a is the answer to this question

explanation:

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
