Someone ? ? : ( julie started with newton's second law of motion. she drew a free-body diagram of an inclined plane experiment. she derived an equation for the acceleration down the inclined plane and determined how it would change if she changed the angle of the incline. from there she was able to derive an equation to find the coefficient of friction of any material on the inclined plane. in the scenario, how did julie determine her findings on the coefficient of friction? a. inductive reasoning b. deductive reasoning from a valid principle c. deductive reasoning from an invalid principle,
