What happens to current during charging and discharging of a capacitor? Ans: During the process of charging the capacitor, the current flows towards the positive plate (and positive charge gets added to that plate) and away from the negative plate. While during the discharging of the capacitor, current flows away from the positive and towards […]

How is cubical expansion calculated? “VOLUMETRIC EXPANSION ” or “CUBICAL EXPANSION”. Consider a metallic body of volume = V1 . Let it’s temperature is raised by T. then experimentally “Increase in volume ( V) is directly proportional to its initial volume (V1) and rise in temperature ( T). What is an example of anomalous Behaviour […]

How can I prove my innocence? To start this process, you should either obtain or write a petition to the court asking for a certificate of innocence. When you fill out a petition, you will need to tell the court: (1) you were convicted of a crime; (2) your conviction was reversed; and (3) you […]

Is 11.9 volts enough to start a car? A flat battery can show 12 volts , but not be good enough to start a car . 11.9v indicates the battery is completely discharged. Anything under 12.2v means the battery is in a state of discharge, and a healthy battery should show 12.6v in a static […]

Which of the following is something you should do after severe weather occurs? clean up flood waters. keep away from windows. create a family safety plan. invite friends over to see the damages. Which of the following conditions lead to hurricane season in the Atlantic region? Explanation: Current oceanic and atmospheric conditions that make an […]

Why does high pressure bring clear weather? The absence of wind in high pressure is due to the lack of an air-pressure gradient. Because rising air cools and results in the condensation of water vapor, which is the reason for clouds and precipitation, downward-moving air and high pressure usually brings mostly clear skies. What is […]

What are 4 examples of potential energy? Examples of Gravitational Potential Energy A raised weight. Water that is behind a dam. A car that is parked at the top of a hill. A yoyo before it is released. River water at the top of a waterfall. A book on a table before it falls. A […]

What type of weather does the California Current bring? The California Current moves less water than the Gulf Stream does. But the California Current has a big effect on the climate of the West Coast of the United States. Usually, the climate along the West Coast is cooler than the climate of inland areas at […]

Is oil a renewable fuel? Renewable fuels are fuels produced from renewable resources. Examples include: biofuels (e.g. Vegetable oil used as fuel, ethanol, methanol from clean energy and carbon dioxide or biomass, and biodiesel) and Hydrogen fuel (when produced with renewable processes). What are the worst fossil fuels? Why is coal the worst fossil fuel […]

What three structural groups shown do all amino acids have in common? All amino acids have the same backbone structure, with an amino group (the α-amino, or alpha-amino, group), a carboxyl group, an α-hydrogen, and a variety of functional groups (R) all attached to the α -carbon. What are the 4 major biological macromolecules? Types […]
