Answer:
r² / 110² − 3z² / 1375² = 1
Explanation:
The equation of a hyperboloid (which is a hyperbola rotated about the z axis or conjugate axis) that is centered at the origin is:
x² / a² + y² / b² − z² / c² = 1
If the cross sections are circular rather than elliptical, then a = b.
(x² + y²) / a² − z² / c² = 1
Or, if you prefer cylindrical coordinates:
r² / a² − z² / c² = 1
We know that at z = 0, r = 110. And at z = -500, r = 130.
110² / a² − 0 = 1
130² / a² − (-500)² / c² = 1
Solving:
a² = 110²
c² = 1375² / 3
Plugging in:
r² / 110² − 3z² / 1375² = 1
I don’t really know the answer cause I need more information about the question

Read Explanation:
Explanation:
If the forces are in opposite directions that means that one of the forces is negative. Therefore you would take the sum of both and if the sum is negative than it is in the direction of the negative force...
EX.
a= -5: <-------
b= 6: --------->
c=a+b
c=(-5)+(6)
c= 1 ---->
Atoms are made up of three particles: protons, neutrons and electrons. Protons and neutrons are heavier than electrons and reside in the center of the atom, which is called the nucleus.Jun 5, 2013-livescience.com
