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
4.The magnetic 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 .

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

Why does earth rotate? because earth is formed from cold gases collapsing due to gravity because the matter in the nebula that formed earth was spinning because earth forms more than 99% of the mass of the solar system because the hydrogen atoms inside the nebula fused to form helium
