Question

multiple choice 1 point which of the following is an example of a lever? d. both b and c b. seesaw a. ramp c. wheelbarrow

Explanation:

To determine the lever example:

• A ramp (A) is an inclined plane, not a lever.
• A seesaw (B) is a first - class lever (fulcrum between effort and load).
• A wheelbarrow (C) is a second - class lever (load between fulcrum and effort).

So both seesaw (B) and wheelbarrow (C) are levers, matching option D.

Answer:

D. Both B and C
