Does this wave have a high or low amplitude?
high
low
Does this wave have a high or low amplitude?
high
low
A wave with a high amplitude has more energy than a wave with a low amplitude.
True
False
The waves will carry the ball to the left It will go to the left of the wave.
The waves will carry the ball to the right It will go to the left of the wave.
the waves will not carry the ball in any direction. It will stay in roughly the same place.

The chart shows the results of an investigation. Which question could be answered from these data?
Does electricity prevent rust?
Will a glowing light bulb get hot?
How long will a battery work?
Which materials conduct electricity?
Which picture shows a closed circuit?
How does energy flow in this circuit?
The battery transfers electrical energy to the wire. The wire carries electrical energy to the light bulb. The light bulb transforms all of the energy into light.
The battery transfers heat energy to the wire. The wire carries the heat energy to the light bulb. The light bulb transforms this energy into motion energy.
The battery transfers electrical energy to the wire. The wire transforms the energy into light energy. The wire transfers the light energy to the light bulb.
The battery transfers electrical energy through the wire. The wire carries electrical energy to the light bulb. The light bulb transforms some of the energy as light, and the rest is transferred to the wire as electrical energy.
Why are patterns important when communicating across a distance?
a. Patterns help keep the message a secret from other people.
b. Patterns of the code allow both the sender and receiver to understand the message.
c. Patterns allow the device to create an electrical signal that travels to the receiver.
d. People who receive the message can use the pattern in the code to create a new code.
