A certain lever system is only 30% efficient. The following changes are considered: change 1: Use a stiffer lever to reduce energy lost bending the lever. change 2: Make a longer lever that will require less force. Which change would make the lever more efficient? (1 point) Responses Change 2 would make the lever more efficient because less energy would be lost. Change 2 would make the lever more efficient because less energy would be lost. Change 1 would make the lever more efficient because this would make it easier to lift. Change 1 would make the lever more efficient because this would make it easier to lift. Change 1 would make the lever more efficient because less energy would be lost. Change 1 would make the lever more efficient because less energy would be lost. Change 2 would make the lever more efficient because this would make it easier to lift.
