A student, while moving out of his old apartment, is loading a rented moving truck using a ramp which is at a rather steep angle of 31.0 ∘ above the horizontal; the ramp is 3.00 m long. At one point in the loading process he drags a loaded suitcase of mass 24.50 kg up the full length of the ramp. The wheels on the old suitcase have long since ceased to function properly, so that the effective coefficient of kinetic friction between the suitcase and the inclined ramp is 0.270. The old suitcase has a strap attached to one corner, and the student does the dragging by pulling on this strap and running up the ramp (he is in a hurry) so that he and the suitcase speed up while going up the ramp. It turns out the the student is able to maintain a tension of 208.0 N during his pull, and the angle between the strap and the incline is 17.0 ∘ (the strap direction is 17.0 ∘ higher than the incline angle).How much work is done on the suitcase by the tension force during the pull up the ramp?

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
