Answer:
Complete Tetanus
Explanation:
The nerve stimulus arrives at the fiber at such a rapid pace that there is no decrease in tension between stimuli detected. This results in a tectanic contraction that is fused (complete) . Thus the muscle fiber does not relax at all due to this complete tetanus.
Answer:
4900 J
Explanation:
Potential energy is the product of the mass, gravitational constant and the height of the object.
U=mgh=10 kg×9.8 m s^(-2)×50 m=4900 J
So, the potential energy of the object is 4900 J.
