Answer 1

Answer:

In a Class Two Lever, the Load is between the Force and the Fulcrum. The closer the Load is to the Fulcrum, the easier the load is to lift. Examples include wheelbarrows, staplers, bottle openers, nut cracker, and nail clippers. A great example of a Class Two Lever is a wheelbarrow.

Answer 2

C) Bottle opener

Second Class Levers

If the load is closer to the effort than the fulcrum, then more effort will be required to move the load. A wheelbarrow, a bottle opener, and an oar are examples of second class levers.
