Help please !!

One magnet is sitting on a table. A second magnet with with the same charge is placed an inch away. The first magnet moves. Which of the following best describes why this happened ?

Select one

1. The gravitational between the two magnets caused energy to be created causing the first magnet to move .

2. The gravitational force between the two magnets resulted in a transfer of energy from the second magnet to the first magnet , causing the first magnet to move

3. The magnetic force between the two magnets caused energy to be created causing the first magnet to move

Calculate the ratio of h+ ions to oh– ions at a ph = 7. 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 = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
