A, B & C would all be correct.
Sarah’s experiment shows that for every 10 centimeters of puck acceleration, the swing length increases by 50 centimeters.
Ph range is 12.53.
<h3>What is PH?</h3>
PH is a proportion of hydrogen particle focus , a proportion of the causticity or alkalinity of an answer. The pH scale for the most part goes from 0 to 14. Fluid arrangements at 25°C with a pH under 7 are acidic, while those with a pH more prominent than 7 are essential or basic. Having a reasonable pH safeguards our bodies from the back to front. Some even say that illnesses and problems can't fill in a body whose pH is in balance. The pH is a logarithmic scale, that is to say, when an answer becomes multiple times more acidic, its pH diminishes by one. In the event that an answer becomes multiple times more acidic, its pH will diminish by two. The pH scale is recognizable to a bunch of standard arrangements whose pH is laid out by peaceful accord. Essential pH standard qualities are resolved utilizing a fixation cell with transaction, by estimating the possible distinction between a hydrogen terminal and a standard cathode like the silver chloride anode.
