What is the function of RL circuit? RL Circuit refers to a circuit having combination of resistance(s) and inductor(s). They are commonly used in chokes of luminescent tubes. In an A.C. circuit, inductors helps in reducing voltage, without the loss of energy. Where are RL and RC circuits used? RC and RL circuits are used […]

What is the projectile motion formula? h = v 0 y 2 2 g . This equation defines the maximum height of a projectile above its launch position and it depends only on the vertical component of the initial velocity. A rock is thrown horizontally off a cliff 100.0 m high with a velocity of […]

How long does it take peeled skin to heal? Peeling skin before it is ready to come off can be counter-productive. After three to four days, most of the peeling should be complete, but it may take anywhere from five to seven days before your fresh, new skin has developed. Within seven to fourteen days, […]

Does microwave use a lot of power? STRANGE though it seems, a typical microwave oven consumes more electricity powering its digital clock than it does heating food. For while heating food requires more than 100 times as much power as running the clock, most microwave ovens stand idle—in “standby” mode—more than 99% of the time. […]

What percentage of oil comes from plastic? About 8% to 10% of our total oil supply goes to making plastic. It is estimated that about 12 million barrels of oil a year are used in making the plastic bags used in the US. An average American throws away about 10 bags a week. What happens […]

What are the final products of mitosis and meiosis quizlet? The end product in meiosis is four cells but the end product of mitosis is two cells. Mitosis and meiosis both start with a single cell. Mitosis produces two genetically identical daughter cells. Meiosis produces four daughter cells with half the genetic material of the […]

What happens if Earth stopped rotating? At the Equator, the earth’s rotational motion is at its fastest, about a thousand miles an hour. If that motion suddenly stopped, the momentum would send things flying eastward. Moving rocks and oceans would trigger earthquakes and tsunamis. The still-moving atmosphere would scour landscapes. Is Earth’s rotation speeding up? […]

Is hot or cold heavier? Cold air is always heavier than an equal volume of hot air. “Air” is actually a mixture of several gases. Which is more heavy hot water or cold water? Cold water is denser than hot water. Therefore, it is cold water that is heavier than hot water (for equal volumes […]

Are wolves endangered 2020? Gray wolves are no longer an endangered species in the continental United States, the U.S. Fish and Wildlife Service announced today, likely setting off a flurry of lawsuits by wolf advocates who believe the decision is premature. Wolves only occupy 20 percent of their historic range throughout North America. When did […]

What is K for the following equilibrium? hence, equilibrium constant=12.23/M. Why does the color get paler again after the pressure increases? Increasing the pressure moves the equilibrium to the left as this decreases the number of moles of gas present in the mixture. The brown colour becomes paler. Why is N2O4 more stable than NO2? […]
