A motorboat is travelling at a constant velocity of 20.0 m/s when it starts to decelerate to arrive at the dock. Its acceleration is a(t)= -(1/4)t² m/s. What is the displacement of the motorboat from the time it begins to decelerate to when the velocity is zero?​

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
