Gravitational Pull Two students stand close to each other. Why do they not get pulled closer to each other due to the
gravitational pull they exert on each other?
A. People do not exert a gravitational force on each other.
OB. The students do not have mass.
OC. The magnitude of the gravitational attraction is too small for them to detect.
OD. They also exert a repulsive electric force on each other that balances the attractive
gravitational force.

What is the most useful equation for electric power?

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
