Two students are listening to two different sounds. First they hear a siren from an fire truck. The siren is very loud. Next they hear children playing in a park. The children are not as loud as the siren. The students discuss why the siren is louder than the children. Which statement is correct?
The siren is louder because the sound is travelling faster through the air.
The siren is louder because the sound wave carries more energy.
The siren is louder because the ambulance is going fast and the dog is not moving.
The siren is louder because it is from a machine.
