Question 1(multiple choice worth 2 points) in order to be considered work, the components that must be present are • a force and a movement in the same direction as the force an action which causes movement and an opposite reaction an action which causes no movement or reaction a force and a movement in the opposite direction of the force

a force and a movement in the opposite direction of the force

Explanation: the equation for work is the force by the distance, gravity is not mentioned in this equation, hence, we can eliminate the force and movement in same direction, there is a force and movement, therefore, we can cross no movement or reaction. Leaving B and D, B is not specific and implies an objects final motion. Leaving D

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
