Question

to get a more intense workout, maya needs to transfer more energy to the battle ropes. one way maya does this is by moving her arms farther up and down to make the waves in the ropes taller. in this graph, the blue line models a wave maya created with a battle rope earlier in her workout. the orange line models a wave maya creates by moving her arms farther up and down. graph: displacement (ft.) on y-axis, position (ft.) on x-axis, blue and orange sinusoidal waves describe what happens when maya moves her arms farther up and down. complete the sentence. maya transfers more energy to the rope and ________ of the wave. options: increases the frequency, decreases the frequency, increases the amplitude, decreases the amplitude

Explanation:

The amplitude of a wave is the maximum displacement from the equilibrium position. When Maya moves her arms farther up and down, the maximum displacement (height) of the wave (as seen in the graph where the orange line has a greater vertical extent compared to the blue line) increases. Frequency is related to how many waves pass a point in a given time, and the graph does not show a change in the number of waves (period) but rather in the height. So, moving arms farther up - down affects the amplitude.

Answer:

increases the amplitude
