Answer:
The x represents the reference point on a motion map
Explanation:
-Motion maps are another way to represent the motion of an object. (other representations are graphical and mathematical models)
The volume of every sphere is
Volume = (4/3) (pi) (radius)³
When you say "across", I think you mean the diameter of the ball.
The radius is half of the diameter = 12 inches.
Volume = (4/3) (pi) (12 inches)³
= (4/3) (pi) (1,728 cubic inches)
= 7,238.2 cubic inches . (rounded)

Negative charge (it has more protons than electrons)
Answer:
See the answers below.
Explanation:
A transformer is a static electrical machine, it should be borne in mind that although the voltage can be increased or decreased, the power must always be equal.
For this case:
The power in the first coil can be calculated by means of the following formula.
where:
V = voltage = 12 [V]
I = current =2 [A]
a)
Therefore the power:
![P=12*2\\P=24[W]](https://tex.z-dn.net/?f=P%3D12%2A2%5C%5CP%3D24%5BW%5D)
b)
Now in the second coil, the power must be the same:
![P_{secondcoil}=V*I\\24=144*I_{secondcoil}\\I_{secondcoil}=24/144\\I_{secondcoil}=0.166[A]](https://tex.z-dn.net/?f=P_%7Bsecondcoil%7D%3DV%2AI%5C%5C24%3D144%2AI_%7Bsecondcoil%7D%5C%5CI_%7Bsecondcoil%7D%3D24%2F144%5C%5CI_%7Bsecondcoil%7D%3D0.166%5BA%5D)
