A Worker Is Fixing A Ladder At The Community Pool. Both The Temperature Of The Water And The Air Is 68

Answers

Answer 1

The speed of water is highest in steel and lowest in air.

In the order : Steel > Aluminium > Water > Air

Steel > Aluminium > Water > Air

which have 16,850 ft/sec > 16,700 ft/sec > 4505 ft/sec > 1,127 ft/sec respectively.

The speed of sound is directly proportional to the density of the medium it propagates in. We know that solid is denser than liquid and liquid is denser that gas. So, the sound going fastest in Steel and Aluminium compared to water and air wich are liquid and gas respectively can be explained. Since it propagates faster in steel than in Aluminium, we can also conclude that Steel is more denser than aluminium.
