Manuel and Sandy were partners. Sandy held the accelerometer in her hands while Manuel watched the water line. Throughout Sandys walk,
the water line remained level. What does that tell the students about
Sandy's motion?
Sandy's velocity changed when she slowed down or
sped up.
A)
Sandy's speed might have changed but her direction
B) did not.
Sandy must not have been moving if the water line
remained level
Sandy's velocity is constant: her speed and direction
did not change.
D)

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
