What is the best developmental theory? Freud’s Psychosexual Developmental Theory Freud proposed one of the best-known grand theories of child development. According to Freud’s psychosexual theory, child development occurs in a series of stages focused on different pleasure areas of the body. What are the key points of Erikson’s theory? Erikson’s eight stages of psychosocial […]
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 long does it take for boiling water to reach room temperature?
How long does it take for boiling water to reach room temperature? Cooling from 100 to 45 in a closed container, not sealed so you don’t get a vacuum, probably takes 100 minutes or so. 50–45 20 min, but you said open pot, so it’s faster, as you get material loss (evaporation/”sensible heat”) as the […]
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 is shift in demand and supply curve?
What is shift in demand and supply curve? In other words, a movement occurs when a change in quantity supplied is caused only by a change in price, and vice versa. Meanwhile, a shift in a demand or supply curve occurs when a good’s quantity demanded or supplied changes even though price remains the same. […]
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 […]
What devices are used for measuring atmospheric pressure and wind speed?
What devices are used for measuring atmospheric pressure and wind speed? A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. A simple barometer consists of a long glass tube (closed at one end, open at the other) filled with mercury and turned upside down into a container of mercury. What instruments […]
Is voltage is directly proportional to resistance?
Is voltage is directly proportional to resistance? Ohm’s law Equation tells us that the current in a circuit can be determined if the values of resistance and voltages are known. Therefore, voltage is not proportional to resistance. Why ammeter has low resistance and voltmeter has high resistance? It must be placed in series with the […]
