Ball pushed from edge of table drops. Strikes toy truck, moves forward strikes dominoes. Dominoes fall uphill and strike pendulum. Pendulum swings and strikes toy racecar. Toy racecar
falls and goes through loop 1 and then loop 2 before falling into cup.

Measurements are listed here:
Height of golf ball on table to where it hits toy truck is 40.0 cm Mass of golf ball is 0.04593 kg
Distance truck moves to reach dominoes is 6.0 cm Mass of toy truck is 0.114 kg
1. (8 points) Compute the E, for the golf ball.

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
