Answer:
In a closed-loop system, matter is used to generate energy, and the energy generated is used to produce matter, and the cycle goes on without end.
Explanation:
A closed-loop system is one in which materials or energy is recycled without end through a production cycle. This means that a raw material is used to produce a finished product, and the finished product at the end of its use cycle is converted back and used as a raw material to produce more of it again. Energy and matter can also be cycled in the same way in an energy and matter closed-loop system, converting matter to energy, and the energy is put back into the production of more of the matter.
B 20 m/s
It should go to 100 that fast nor 40
Answer:
62.1 kg
Explanation:
Weight = mass × acceleration
609 N = mass × (9.8)
The acceleration is 9.8 because that is the acceleration of gravity.
Divide both sides by 9.8 to isolate the mass.
609N/9.8 = mass
62.1 kg =mass
