If the same amount of force were applied to all four balls in the picture, which would experience the greatest change in motion?
a) 5kg
b) 10kg
c) 20kg
d)40kg

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

The force it would take to accelerate an 900-kg car at the rate of 6m/s2

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
