How do capacitors behave in an AC and DC circuit? When capacitors are connected across a direct current DC supply voltage, their plates charge-up until the voltage value across the capacitor is equal to that of the externally applied voltage. Then the Capacitance in AC circuits varies with frequency as the capacitor is being constantly […]
What is the meaning of atomic nuclei?
What is the meaning of atomic nuclei? The atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment. Almost all of the mass of an atom is located in the nucleus, with a […]
What is x0 SHM?
What is x0 SHM? Oscillating Systems● An oscillating system is defined as one thatobeys the general equation:● Here● the amplitude is x0● The angular frequency ensures that the real timeperiod coincides with the angular period of 2πradians● The phase allows for an oscillation that starts at anypoint.x=x0 sin(ωt+ ϕ) Where are oscillators used? Oscillators convert […]
What increases yield strength?
What increases yield strength? Increasing the concentration of the solute atoms will increase the yield strength of a material, but there is a limit to the amount of solute that can be added, and one should look at the phase diagram for the material and the alloy to make sure that a second phase is […]
Which of these is found only in experimental investigation?
Which of these is found only in experimental investigation? Which part of an investigation is only found in an experimental investigation the answer is a control group. What steps are included in a descriptive investigation? Be sure to have: Make an observation about a phenomenon (qualitative and/or quantitative) Ask a research question. Hypothesize a possible […]
Why is a white car cooler than a black car on a hot day?
What is the difference between Fermi energy and Fermi level?
What is the difference between Fermi energy and Fermi level? The Fermi energy is only defined at absolute zero, while the Fermi level is defined for any temperature. The Fermi energy is an energy difference (usually corresponding to a kinetic energy), whereas the Fermi level is a total energy level including kinetic energy and potential […]
What are the 5 major latitude lines?
What are the 5 major latitude lines? Important lines of latitude: the equator (0°) the Tropic of Cancer (23.5° north) the Tropic of Capricorn (23.5° south) the Arctic circle (66.5° north) the Antarctic circle (66.5° south) the North Pole (90° north) the South Pole (90° south) Which is the shortest longitude? Technically 90°N and 90°S […]
In what conditions does displacement become zero?
In what conditions does displacement become zero? When the final position and initial position of the object is same then displacement is said to be zero for example an object/body moving in a circular motion when reaches the starting point after completing one complete cirecle is said to have zero displacement. Can displacement be zero […]
What is the rule of first blood?
What is the rule of first blood? The “rule of first blood” states that if two hunters each fire an arrow into an animal, the one who can claim the animal is the first to ____________________________________________ _________________________________________________. 1. How long does your scent stay in the woods? about 2-3 days Does rain wash away human […]
