spinal fluid. The cells are one type of neuroglia
cells of the central nervous system. The lining of ependyma cells of the brain also
plays a role in neuroregeneration.
Answer:
Same, 50N
Explanation:
According to Newton's third law, any force exerted on an object is exerted back with the same magnitude. The magnitude of the action force is the same as the magnitude of the reaction force. In the example, the chair would be pushing back with a magnitude of 50N.
I hope this answer helps.
