A guitar is played by striking or plucking its strings. This plucking action results in sound. The sound is created by

• the electrical connection to the guitar.

• the vibrations of the body of the guitar.

• the vibrations in the strings being plucked.

• the vibrations in the fingers plucking the strings.

The table shows the number of times metal wires vibrate per second when they are plucked one by one. Which wire produced the sound with the highest pitch?

• Wire 1

• Wire 2

• Wire 3

• Wire 4

Sarah and Maria made a telephone using two cans and a string. It was a very long string. Maria went upstairs in her house and Sarah stayed downstairs. Maria spoke softly into the can. "I can hear you!' Sarah said back. How can this happen?

• Sound waves travel through a vacuum.

• Sound waves travel from high to low.

• Sound waves travel through solids like the string.

• Maria talked so loudly that Sarah could hear her without the phone.
