Two tin cans are connected by a long string. When two people holding them stand very far apart and speak at a normal volume, they cannot hear each other. But when they speak into the can and hold it up to their ears, they can hear each other. Explain why this happens.(1 point)

When they attempt to talk normally, the sound waves from their voices do not travel far enough. When they speak into the can, their sound waves are turned into electric signals, which run down the string. When they get to the other side, these signals are converted back into sound waves, which can be heard.

When they attempt to talk normally, the sound waves from their voices do not travel far enough. When they speak into the can, their sound waves are turned into vibrations, which run down the string. When they get to the other side, they vibrate the other can. This turns the vibrations back into sound waves, which can be heard.

When they attempt to talk normally, the sound waves from their voices do not travel far enough. When they speak into the can, their sound waves travel directly down the string, then come out the other side.
