Final answer:

Explanation of first, second, and third order levers using examples like wheelbarrow, broom, and scissors.


Explanation:

Wheelbarrow: Second order lever - The load (weight) is situated between the pivot (fulcrum) and the input force (effort). This arrangement allows the wheelbarrow to lift heavy loads with less effort.

Broom: First order lever - The pivot is positioned between the input force (effort) and the load. An example is when you use a broom to lift a load with your hand as the effort and the load on the other side of your hand as the load.

Scissors: First order lever - Scissors work as a first order lever where the pivot point (fulcrum) is in between the effort applied to the handle and the load (cutting action).
