5. A 60-kg man is in an elevator that is accelerating down- ward at the rate of 1.4 m/s2.
a. What is the true weight of the man in newtons?
b. What is the net force acting on the man required to pro-
duce the acceleration?
C. What is the force exerted on the mans feet by the floor of the elevator
D. What is the apparent weight of the man in Newton’s
E. How would your answers to part b through d change if the elevator were accelerating upward with an acceleration of 1.4 m/s2.

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
