0.2 Hz = v / (0.03 m)
<span>6.67 m/s
best i can guess</span>
Answer:
0.017 s
Explanation:
The period of a periodic signal is defined as the reciprocal of the frequency:
where
T is the period
f is the frequency
For the electrical power, the frequency is
f = 60.0 Hz
Substituting into the previous equation, we find the period:
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.
