A pulley system is operating at only 50% efficiency. How could the efficiency be increased? (1 point) Responses by decreasing the amount of weight being lifted by decreasing the amount of weight being lifted by reducing the friction on the pulleys by reducing the friction on the pulleys by adding more pulleys to the system by adding more pulleys to the system by having a second person pulling on the rope

To increase the efficiency of a pulley system operating at only 50% efficiency, the best approach would be **by reducing the friction on the pulleys**. Lowering friction allows for a smoother operation, which can enhance the overall efficiency of the system.
Adding more pulleys can redistribute the load and potentially reduce the force needed to lift a weight but doesn’t necessarily improve the efficiency if friction remains high. Reducing the weight being lifted or having a second person pull the rope may not directly address the inherent inefficiencies in the system itself.
