Question

part 1: ocean waves & energy
a buoy (shown on the left above) and a pelamis (shown on the right above) are tools that are used to convert ocean wave energy into electricity or other forms of usable energy.

1. on the amplitude & energy chart, as you move down the chart, the amplitude (increases / decreases).
2. on the amplitude & energy chart, as you move down the chart, the energy (increases / decreases).
3. therefore, the relationship between amplitude and energy is that as the amplitude

then the energy

amplitude | .5 | 1 | 1.5 | 2 | 2.5
buoy energy | 11 | 47 | 106 | 198 | 250
pelamis energy | 29 | 116 | 261 | 464 | 725

Explanation:

Step1: Analyze Amplitude Trend

Check the Amplitude column: values are 0.5, 1, 1.5, 2, 2.5 (increasing as we move down the chart).

Step2: Analyze Buoy Energy Trend

Buoy Energy values: 11, 47, 106, 198, 250 (increasing as Amplitude increases).

Step3: Analyze Pelamis Energy Trend

Pelamis Energy values: 29, 116, 261, 464, 725 (increasing as Amplitude increases).

Step4: Determine Relationship

From both energy columns, as Amplitude (0.5→2.5) increases, Energy (Buoy: 11→250; Pelamis: 29→725) also increases.

Answer:

1. increases
2. increases
3. increases, increases
