A student performs an experiment by ringing a bell in the air and ringing a bell in a pool. He measures the time it takes for a friend to hear the bell. Make and justify a hypothesis on which medium the friend would hear the bell the fastest.(2 points)

The hypothesis is that the friend would hear the bell in the air faster than in the pool. This is because sound travels faster through air than through water. In air, sound travels at a speed of approximately 343 meters per second, while in water, sound travels at a speed of approximately 1,480 meters per second. Therefore, it is expected that the friend would hear the bell in the air faster due to the higher speed of sound transmission in air.

The friend is hypothesized to hear the bell faster in the air than in the pool, as sound travels faster through air than through water due to the higher speed of sound transmission in air compared to water.
