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.
An epiparasite is a parasite that parasitizes another organism that is also a parasite. Epiparasites are also called hyperparasites or secondary parasites. They feed on another organism, but they do not kill the organism they feed on.
Answer:
Power = 47.0 Watt
Explanation:
As we know that friction force is given by
now we have
m = 6.0 kg
now we have
now since we need to find the rate of work done by friction force
so we can say rate of work done is power due to friction force
so it is given as
Answer:
Explanation:
Recall that density is defined as and that relative uncertainty is defined as where is the uncertainty in the measure and a the measure, To find the uncertainty when two physical quantities are divided, their relative uncertainties are added and then multiplied with the division result of the quantities.
We have:
To find the percent uncertainty, we multiply the relative uncertainty by 100%.
