Number 1 do a data table on paper and do as it was said, then go into Microsoft Excel and put your chart in. For 2 make a line graph(as stated) and do what it tells you.For 3 do as said with the line graph or whatever it should look somewhat like a math chart(the coordinate plane) and do as said. For number 4 help him/her study the charts and analyze the difference between the two. And for number 5 make him/her choose one element and research and write down the questions.
Answer:
By the vibration of particles in a medium
Explanation:
For example, the energy in sound waves is transferred by the vibration of the molecules in air.
A is wrong. Electromagnetic radiation transfers energy through vibrating electric and magnetic fields.
B is wrong. Sound waves can transfer energy far from the ocean.
C is wrong. A combination of waves just makes a wave with a different shape.
