Answer:
A wave of compression and rarefaction, by which sound is propagated in an elastic medium such as air.
B: an increase in acceleration caused an increase in force.
This is based on the concept of force on an object.
Now, formula for force is commonly known as;
Force = mass × acceleration
Now, mass and acceleration are the input values that make the output which is the Force to either increase or decrease.
- Now, for the line of dominoes to fall, it means that the force was so overwhelming that the dominoes couldn't resist it.
Now, this output which is the force became so much as a result of the increase in acceleration of the motion that triggered its movement.
Moreover, the force is directly proportional to the acceleration!
Thus, we can say that an increase in acceleration caused an increase in force.

Hello!
Here we can use PE=mgh
So with your givens we have
Mass=17kg
PE= 350J
g=9.80m/s^2
So we have
350J = 17kg * 9.80m/s^2 * h
Now we just solve for our height! So we have
350J/(17kg*9.80m/s^2) = 2.10m is the height of the shelf. So rounded to nearest whole number, the shelf is 2meters high.
Hope this help. Any questions please just ask. Thank you so much!
