The answer is: To have easy access to a coolant for the reactor.
Hope this helps!:)

The current made by the circuit produce this effect by generating a magnetic field that attracts the car magnetically to the crane lift and is denoted as option C.
<h3>What is a Crane?</h3>
This is a machine which is used to lift and lower objects which are most times heavy.
It employs the use of magnetic force as it is generated when the button is switched on in this scenario.

Answer:
h = 12.6 cm
Explanation:
given,
ground reaction = 788 N
time of force application = 0.9 s
BW = 670 N
Net force = 788 - 670
= 118 N
impulse = F x t
I = 118 x 0.9
I = 107.1 N s
impulse is equal to change in momentum
![v = \dfrac{I}{m}](https://tex.z-dn.net/?f=%20v%20%3D%20%5Cdfrac%7BI%7D%7Bm%7D)
![v =\dfrac{107.1}{\dfrac{670}{9.8}}](https://tex.z-dn.net/?f=%20v%20%3D%5Cdfrac%7B107.1%7D%7B%5Cdfrac%7B670%7D%7B9.8%7D%7D)
v = 1.57 m/s
v is the initial velocity before jump
now, height of center of mass
using equation of motion
v² = u² - 2 g h
![h = \dfrac{u^2}{2g}](https://tex.z-dn.net/?f=h%20%3D%20%5Cdfrac%7Bu%5E2%7D%7B2g%7D)
![h = \dfrac{1.57^2}{2\times 9.8}](https://tex.z-dn.net/?f=h%20%3D%20%5Cdfrac%7B1.57%5E2%7D%7B2%5Ctimes%209.8%7D)
h = 0.1257 m
h = 12.6 cm
the height of center of mass is equal to h = 0.126 m or 12.6 cm
