Question

explain why a seesaw is closest in arrangement to a first class lever.

Explanation:

In a first - class lever, the fulcrum is between the effort and the load. On a seesaw, the pivot point (fulcrum) is in the middle, with people applying effort (weight) on either side. So, it matches the first - class lever arrangement.

Answer:

A seesaw is closest in arrangement to a first - class lever because its pivot point (fulcrum) is located between the two points where people sit (the effort and load points).
