Shani as The Statue of Liberty: Did She Do Any Work?
Question:
Shani poses as the statue of liberty for an art class. She holds a torch above her head with her right hand and a book against her side with her left hand. She holds the pose for ten minutes. At the end of the session, she mentions to her friend that it was a lot of work to pose and that her arms are really tired. Which describes the work Shani did while she posed?
Answer:
She did no work while she posed because she did not move the torch or the book.
Explanation:
Work done is equal to the force exerted multiplied by the distance traveled.
For the physics laws, work is calculated using the formula:
W = F * D
Where W represents work, F represents force, and D represents distance. In this situation, since Shani did not move the torch or the book while holding her pose as the Statue of Liberty, she did not perform any work. In physics, work is only done when a force is applied and there is a displacement or movement over a distance.
