Answer: False</h2>
Explanation:
This sentence is the description of the mechanical energy.
In this sense, the mechanical energy of a body or a system is that which is obtained from the speed of its movement (kinetic energy) or its specific position (potential energy), in order to produce a mechanical work.
That is to say: The mechanical energy involves both the kinetic energy and the potential energy (which can be elastic or gravitational, for example).
In addition, it should be noted that mechanical energy is<u> conserved in conservative fields and is a scalar magnitude.</u>
Therefore:
<h2>The sum of potential and kinetic energies in the particles of a substance is called <u>Mechanical Energy</u></h2>
The force must be made over a distance

Answer:
Vtennis = 134 [cm^3]; Vgolf = 40.76 [cm^3]
Explanation:
To solve this problem we must have the values of the radius or diameters of each of these balls, therefore performing an internet search we can appreciate that the diameters of these balls are:
Dt = 6.35[cm]
Dg = 4.27[cm]
But we need the radius, and we know that the radius is equal to the half of the diameter.
Rt = 3.175 [cm]
Rg = 2.135 [cm]
Now replacing this values in the given equation:
![V = \frac{4}{3} *\pi *r^{3}\\ V_{tennis}= \frac{4}{3} *\pi *(3.175)^{3}\\ V_{tennis}= 134.06[cm^3]\\\\ V_{golf}= \frac{4}{3} *\pi *(2.135)^{3}\\V_{golf}= 40.76 [cm^3]](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2Ar%5E%7B3%7D%5C%5C%20V_%7Btennis%7D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%283.175%29%5E%7B3%7D%5C%5C%20V_%7Btennis%7D%3D%20134.06%5Bcm%5E3%5D%5C%5C%5C%5C%20V_%7Bgolf%7D%3D%20%5Cfrac%7B4%7D%7B3%7D%20%2A%5Cpi%20%2A%282.135%29%5E%7B3%7D%5C%5CV_%7Bgolf%7D%3D%2040.76%20%5Bcm%5E3%5D)
