<span>A voltage source in a circuit provides electrical ENERGY.
In fact, a voltage source is a device (like a battery) that creates a potential difference between two points of the circuit. This potential difference allows charge carriers to move from one side of the device to the other side, flowing through the circuit, producing a current, and current is a form of electrical energy.</span>
When two waves (either mechanical or electromagnetic) combine in such a way that their peaks and troughs combine to produce a wave of large amplitude, the wave behaviour is known as constructive interference. The opposite process is where the peaks of one wave combines with the troughs of another wave in order to produce a wave of smaller amplitude. This process is known as destructive interference.
Answer:
B. 90km/hr
Explanation:
The formula for finding velocity =
Displacement/time
The displacement of the car has been given to be = 1215 km West
Time it took to go from Dallas to Paso = 13.5 hours
Then velocity = 1215/13.5
= 90
Therefore velocity = 90km/hour
Option B is the correct answer to this question.
Thank you!
Answer:
They include;
1. Earthquakes
2. Floods
3. Hurricane
4. Landslide
5. Tsunami
6. Tornadoes
Explanation:
Emergencies are sudden disasters that occur occasionally and unexpectedly, resulting in massive destruction of lives and property, and which require prompt actions to resolve. When some of these emergency situations occur, the electric grids could fail, resulting in a power outage in the affected town or community. Rescue workers might then find communication difficult because they cannot get energy to their electrical devices.
Examples of emergency situations that could have this type of effect include; Earthquakes, Floods, Hurricane, Landslide, Tsunami, and Tornadoes.
