PLEASE HELP ONLY NINE DAYS LEFT I WILL GIVE BRANLIEST Jennifer and Mark make paper airplanes. They are conducting an experiment to see which airplane design will travel a longer distance. What do they need to do to properly conduct their experiment?

A. Apply the same force of motion when they release the airplanes.
B Apply different forces of motion when they release the airplanes.
CThrow one airplane into the wind and the other airplane against the wind.
D Use the force of the wind to decide which will travel farther.

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
