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 this would make it easier to lift. Change 2 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 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 2 would make the lever more efficient because less energy would be lost.

Answer 1

Change 1 would make the lever more efficient because less energy would be lost. By using a stiffer lever, you reduce the energy lost due to bending. While making the lever longer in Change 2 could potentially make it easier to lift with less force, it does not directly address the energy losses in the system. Therefore, improving the efficiency by minimizing energy loss is the more effective option.
