Question

eli is playing with a spring toy. energy from his hand is transferred to the spring toy, creating a wave. as the wave moves through the spring toy, the coils in the spring toy move back and forth. select the true statements. the wave carries energy through the spring toy. the spring toy is the medium the wave travels through. eli transfers energy to the spring toy. the coils in the spring toy move up and down.

Explanation:

• Waves carry energy. Since Eli's hand transfers energy to create the wave in the spring toy, the wave carries that energy through the toy.
• A medium is what a wave travels through. Here, the spring toy is the medium.
• The problem states "Energy from his hand is transferred to the spring toy", so Eli transfers energy to it.
• The problem says "the coils in the spring toy move back and forth", not up and down.

Answer:

• The wave carries energy through the spring toy.
• The spring toy is the medium the wave travels through.
• Eli transfers energy to the spring toy.
