The speed of sound is not constant in all materials. speed of sound is determined by elasticity,density, and temperature. S<span>ound does travel faster in solids than in water and air.
Vaccum is an empty space through which sound cannot travel through. This is because sound is basically vibrating properties and in a vacuum there are no properties.</span>
Answer:
<h3>Newton's 2nd law states acceleration is proportional to the net force acting on an object. The net force is the vector sum of all the forces applied to the object. ... In this case the acceleration (slowing down) of the puck is proportional to the amount of friction.</h3>

Explanation:
Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium.
Explanation:
8 m × (1000 mm / m) = 8000 mm
