Two beginning ice skaters collide into each other. They were both moving in the same direction initially but the first skater (with a mass of 65 kg) was moving at 2.4 m/s and the other (with a mass of 84 kg) was moving at 5.6 m/s. The faster skater catches up to the slower one and they have an inelastic collision, moving together at the same velocity afterward. What is this velocity? (Round your answer to the nearest tenth.)

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

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
