Answer:
Entropy of the universe is constantly increasing.
Explanation:
Entropy is the loss of available energy when it is in transit. The entropy of a system increases consuming the energy, this energy is now unavailable for doing the work or making the corresponding changes in the property of a system.
Entropy is the measure of randomness of a system. It is a toll that the nature takes for energy in transit.
The second law of thermodynamics concludes that all the energy cannot be transformed from one form to another and the flow of energy has a specific direction.
If a reversible process occurs, there is no net change in entropy. In an irreversible process, entropy always increases, so the change in entropy is positive. The total entropy of the universe is continuously increasing.
Answer:
C
Explanation:
i could be wrong but it seems the most logical
If the bag is motionless, then it's not accelerating up or down.
That fact right there tells you that the net vertical force on it
is zero. So the sum of any upward forces on it is exactly equal
to the downward gravitational force ... the bag's "weight".
If the bag is suspended from a single rope, then the tension
in the rope must be equal to the 100-N weight of the bag.
And if there are four ropes holding it up, then the sum of
the four tensions is 100N. If the ropes have been carefully
adjusted to share the load equally, then the tension is 25N
in each rope.
Answer:
Worldwide Radio Communication
Explanation:
The ionosphere is important because it is through the ionosphere that world wide radio communication is possible.
[I researched for you, since I am not in that particular level to know that knowledge yet. I assure this is accurate info :)]
The answer is A, red.
