The sound wave would behave differently in a swimming pool than in his bedroom because sound waves travel faster in more dense mediums; such as water. The wave will travel faster in water, and slower in air.
S=Vt
110=V(72)
110/72=V
V=1.527m/s
The branch of physics that deals with the study of force energy and motion is classic mechanics
Answer:
another. persist. continue. last. remain.
Explanation:
The formula for kinetic energy is
KE = (1/2) (mass) (speed)² .
How you measure the object's mass and speed is up to you.
You'd need different methods for different objects, and in some
cases, you'd need quite a bit of ingenuity.
