Question

A controlled experiment has
       all factors tightlyregulated.
       a known outcome everytime the experiment is run.
       all the influencingfactors identical except one.
       no practicalvalue.


Which of the following correctly states Newton's third law ofmotion? Forces occur in matched pairs that are
       equal in magnitude andequal in direction.
       opposite in magnitudeand equal in direction.
       equal in magnitude andopposite in direction.
       opposite in magnitudeand opposite in direction


Which of the following is NOT a physical property that a scientistmight use to describe gold?
       yellowishcolor
       shiny metallicluster
       valuable
       dense

A change in the state of motion is evidence of
       a force
       an applied force that isunbalanced.
       a force that has beenworn out after an earlier application
       Any ofthese. A controlled experiment has
