Karissa is conducting an experiment on the amount of salt that dissolves in water at different temperatures. What can Karissa do to increase confidence in the results of her experiment? Check all that apply. have another scientist run the same exact procedure in her lab include several other liquids for comparison e calculate the average amount of salt that dissolves to summarize findings test water temperature many times with the same procedure make sure the experiment follows a specific procedure that allows other scientists to produce the same findings

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
