No, I do not agree with her. In order for sounds to be heard, the sound
wave produced by a vibrating object needs to travel from the vibrating
object to the ear through a medium.
<span>Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction. ...Lubrication is another way to make a surface smoother. ...Make the object more streamlined. ...Reduce the forces acting on the surfaces. ...<span>Reduce the contact between the surfaces.

Answer:
A. mass
Explanation:
<u>Mass</u> determines the quantity of inertia for an object. Mass is the quantity that depends upon the inertia of an object. The inertia that an object has is directly proportional to the mass of the object.
An object that has more mass has a greater tendency as compared to the object that has less mass to resist changes in its state of motion.
Answer:
m/s^2, acceleration
Explanation:
velocity in SI units is meter / second
dividing by time(second) gives meter / second^2 which is acceleration.
