2. a 2,500 kg car traveling to the north is slowed down uniformly from an initial velocity of 20 m/s by a 6,250 n braking
force acting opposite to the car's motion. use the impulse momentum equation to answer the following what's the
velocity after 2.5 s?

The mini-refrigerator fire was most likely caused by what type of wiring?

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
