 2.  During an electronics experiment in your laboratory, you measure the voltage at terminal A on your newly designed circuit. You measure14volts. You check the same terminal after making a small change to the circuit and this time you measure19volts. What was the voltage difference between the two readings?


3.  In physics, a deceleration (the slowing down of an object in motion) is considered a negative acceleration (in other words, the opposite of speeding up). If you crash a small toy car into a wall, and the acceleration of the car is6m/s^{2}, what would be the total acceleration you would have applied to the car, if you repeated the crash fifteen times?

 4.  Cody and Amanda are playing a game in which each player either wins, loses, or draws (ties) at each turn. The winner of a turn is awarded 5 points, and the loser loses 5 points.
