You have a Class One lever that is 2 m in length. The distance from the fulcrum to the effort is 0.6m while the distance from the load to the fulcrum is 1.4m. Force or Power advantage?

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.

The answer is a. yes, it asks a question that can be answered correctly (by measuring hands).
