Mr. Cohen is a scientist who was testing the efficiency of a 9V battery by measuring how much electrical energy releases he determines that 7v of energy is converted to electrical energy which of these formulas shows how to calculate the efficiency of the battery

If you have a bowl with six apples and you take away four, how many do you have? anyone take a guess and post it. lol getting rid of my account might as well do it with some fun
