Answer:
Acceleration of gravity=
Explanation:
Newton's Second Law-acceleration is proportional to the net force acting on an object.
All objects usually free fall at the same acceleration of
-this regardless of their mass. This acceleration is known as acceleration of gravity.
Pressure is defined as the force per unit area on a body.
1 - Vibrate east and west
Sound waves are <em>longitudinal waves</em>, that means the vibrations are parallel to the direction of energy transfer. If the energy transfer is going East, then the vibrations will be East and West creating compressions and rarefactions in the air.
Which are in constant motion.
E = 0.25 = m*g*h
<span>h = 0.25/(m*g) = 0.25/(0.125*10) = 0.25/1.25 = 1/5 = 0.20 m
I hope this helps you have a great day and im sorry it took so long to get an answer</span>
