What happens to the potential difference across bulb B? The potential will be the same at any point before the bulb and any point after the bulb before the gap. Therefore, the potential at A is the same as the positive terminal of the battery, and the potential at B is the same as the […]
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 […]
How do capacitors behave in an AC and DC circuit?
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 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 […]
Why is a white car cooler than a black car on a hot day?
What are the impacts of a volcanic eruption?
What are the impacts of a volcanic eruption? Among the hazards in distant areas are the effects of toxic volcanic ashes and problems of the respiratory system, eyes and skin, as well as psychological effects, injuries, transport and communication problems, waste disposal and water supplies issues, collapse of buildings and power outage. What is Volcano […]
What are the 3 main economic systems?
What are the 3 main economic systems? This module introduces the three major economic systems: command, market, and mixed. We’ll also discuss the characteristics and management implications of each system, such as the role of government or a ruler/ruling party. What is the best type of economy? A free and competitive market economy is the […]
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 […]
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 […]
