A chair takes 5s to go from 4m/s to 0m/s. What is the force needed to stop the 10kg chair? A force of 25N is being applied to a box on the ground. If the mass of the box is 6kg and the box is accelerating at 3.33m/s2, what is the force of friction from the ground?

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
