What are the three levels of the federal court system? The federal court system has three main levels: district courts (the trial court), circuit courts which are the first level of appeal, and the Supreme Court of the United States, the final level of appeal in the federal system. What are two examples of cases […]
What is the fifth state of matter?
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 […]
What does snow do to trees?
What does snow do to trees? Excess snow can damage trees and woody shrubs by bending, breaking and splitting them or causing them to fall or uproot. Whether woody plants will be damaged in one of these ways depends upon several factors. Coniferous evergreens, for instance, can bear more snow weight than broadleaf evergreens. What […]

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? […]
How do you find the speed of a molecule?
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 happens when intensity is doubled?
What happens when intensity is doubled? Any change in the energy of the photons will not change the intensity. So if intensity is doubled, the no. of photons incident on the surface will be doubled and as a result more photoelectrons will be ejected. What is the value of maximum usable frequency when the incident […]
