Uma esfera de aço é abandonada em uma rampa inclinada na qual está colocada uma fita métrica graduada em centímetros, como representa a figura. Sabendo que a aceleração escalar da esfera é praticamente constante e igual a 5 m/s2, calcule sua velocidade escalar V no final da rampa.

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
