An illustration shows a system of two pulleys lifting a block.
In this pulley system, the pulleys will decrease the mechanical force required to lift the block and will change the direction of the force.
In this pulley system, the pulleys will decrease the mechanical force required to lift the block and will change the direction of the force.
To complete the statement, you can analyze the diagram of the pulley system.
First, determine the effect of the pulleys on the mechanical force required to lift the block. Look for the number of ropes or cables attached to the block. Each rope or cable represents a force pulling up on the block. If the diagram shows more than one rope or cable, it means that the mechanical force required to lift the block will be decreased.
Second, determine the effect of the pulleys on the weight of the block. The weight of the block is the force pulling downward on it due to gravity. Pulleys do not change the weight of the block. Therefore, the weight of the block will remain the same.
Based on this analysis, the correct completion for the statement would be: "In this pulley system, the pulleys will decrease the mechanical force required to lift the block and will not change the weight of the block."
