Answer:
By action potential nerve contract the muscle
Explanation:
The muscle contract when the nervous system sends action potential to the muscle. So the nervous system delivers signal to muscle, the first signal reaches the neuromuscular junction. The signals are passed by a chemical messenger called neurotransmitter release by motor neurons, the chemicals bring reaction and shorten the muscle fibre. When neurotransmitter are absent or reduce in concentration the process reverse and muscle relax again.
The answer is false because kinetic energy is supposed to be energy that a body possesses. so active energy
Answer:
1,6 m / s ^ 2
Explanation:
De las leyes de Newton;
Fuerza = masa × aceleración
masa = 275 kg
Fuerza = 440 N
Aceleración = Fuerza / masa
Aceleración = 440N / 275Kg
Aceleración = 1,6 m / s ^ 2
