I believe the density will decrease, because if you look at the equation d=m/v. This can also be written as d=m(1/v). So if you increase volume, let's say you increase from 10ml to 1000ml. And keeping mass same, say 5 grams,then instead of having 1/10= 0.1ml then putting the equation together as 5x0.1. You will have for the second equation 5x(1/1000ml)= 5x0.001. You can see for yourself after multiplying these 2 values from the different equation which density value is smaller and larger.
A transverse wave always move perpendicularly from its medium. In the problem the medium is the rope. So when the transverse wave movement is left and right, the perpendicular equivalent movement of the rope is up and down.
Answer:
Acceleration is the rate of change of velocity.
When the velocity of an object does not change, i.e., when the velocity is constant, the acceleration is <em>zero</em>.
Mathematically (differential form),
<h3><u>Zero</u> is the right answer.</h3>
