A gallon of gasoline contains chemical energy. If you pour a gallon of gasoline into your car, you could drive for about 20 miles on the highway (about 20 minutes). You could choose instead to run a lawn mower for an hour with one gallon of gasoline. If the gasoline were to come in contact with a fire, the entire gallon would burn in less than a minute. Which reaction has the most power?
A. Burning the gasoline in the car
B. Burning the gasoline in a fire
C. Burning the gasoline in the lawn mower
D. They are equal because the gasoline has the same chemical potential energy in each case

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
