What is the fifth state of matter? There are four states of matter common in everyday life — gases, liquids, solids, and plasmas. However, there is also a fifth state of matter — Bose-Einstein condensates (BECs), which scientists first created in the lab 25 years ago. Is plasma The Fifth Element? Science is also getting […]
How many years will it take to clean the ocean?
How many years will it take to clean the ocean? How long will it take to clean up a gyre? A complete cleanup of a gyre is unrealistic, but calculations show we can clean up 50% of the Great Pacific Garbage Patch five years from full-scale deployment of our systems. Why are ocean gyres important? […]
Are NPN and PNP transistors interchangeable?
Are NPN and PNP transistors interchangeable? Answer: NPN and PNP transistors are interchangeable if you remember one simple rule: A bipolar transistor is essentially two back-to-back diodes with the base being the common connection. The collector (C), on the other hand, goes to +V — in effect, reverse biasing that diode. Can you convert PNP […]
How do you find the distance and midpoint?
What are the energy conversion devices?
What are the energy conversion devices? Devices Dynamo. Mechanical energy into electrical energy. Electric motor. Electrical energy into mechanical energy. Microphone. Sound energy into electrical energy. Loud speaker. Electrical energy into sound energy. Electric Bulb. Electrical energy into light and heat energy. Solar cell. Candle. Sitar. Which of the following is an example of a […]
Does voltage stay the same in series?
Does voltage stay the same in series? 2. In a series circuit the current is the same at any particular point on the circuit. 3. The voltage in a series circuit, however, does not remain constant. Why does voltage decrease in a series circuit? In series circuits, the resistor with the greatest resistance has the […]
What happens when there is an open circuit?
What happens when there is an open circuit? An open circuit implies that the two terminals are points are externally disconnected, which is equivalent to a resistance R=∞ . This means that zero current can flow between the two terminals, regardless of any voltage difference. How do you know if you have an electrical problem? […]
Why is zener diode reverse biased?
Why is zener diode reverse biased? When connected in parallel with a variable voltage source so that it is reverse biased, a Zener diode conducts when the voltage reaches the diode’s reverse breakdown voltage. From that point on, the low impedance of the diode keeps the voltage across the diode at that value. What do […]
What does it mean if a charge is in equilibrium?
What does it mean if a charge is in equilibrium? Equilibrium condition states that the magnitude of force F1 and magnitude of force F2 should be equal to one another. How does the electric field due to an infinite line of charge vary with the distance from the line? We have found that the electric […]
What is the format of references?
What is the format of references? “References” is centered 1-inch down. It’s not capitalized, bold, or italicized. The reference citations are double spaced with no additional lines between them. References that go past the first line have a hanging indent. How do you write a reference example? How to write a character reference letter Start […]
