Answer:
D. Meters/Seconds
Explanation:
The time period of a wave is measured in seconds.
A typical wave involves both time and distance. Consider a sound wave, which is basically a periodic modulation of the local air pressure. We "hear" the sound because our ears respond to the variations of pressure.
The most common metric of a sound wave is frequency. This is the rate at which the change in pressure occurs, and is measured in cycles per second, formally known as "hertz". The period is the inverse of frequency andl has the units of seconds per cycle, commonly stated simply as seconds.
Answer:
each resistor draws 1/3 of an amp or 0.33333 amps
Explanation:
V = I * R
V = 10 volts
R = 30 ohms
10 = I * 30 Divide by 30
10/30 = I
I = 0.33333
Power = Work done/Time taken
So, keeping this in mind,we can solve it as follows:
= 700/3.1
= 7000/31
= 225.80 W
Answer: False
Explanation:
The potential energy is called organized energy because it is not related to the mass movement of the molecules.
Heat is disorganized energy because it is related to the mass movement of the molecules. Entropy is related to the randomness of the molecules.
If the randomness of the system increases then the entropy will increase. The entropy of the system either remains constant or increases.
The entropy of the system never decreases.
Therefore, the answer will be false.
