Can we slow or even reverse global warming? Yes. While we cannot stop global warming overnight, or even over the next several decades, we can slow the rate and limit the amount of global warming by reducing human emissions of heat-trapping gases and soot (“black carbon”). How you can stop global warming? How Can We […]
Is sand a good thermal insulator?
Is sand a good thermal insulator? Saturated sand has a thermal conductivity in the range of 2-4 W/m-K which causes the sand layer thickness to go astronomical. Thus it can be shown that sand is a good replacement for fiberglass pipe insulation in underground, direct buried applications. It’s easier to install and costs less. Does […]
Why do plasma balls make you smell?
Why do plasma balls make you smell? If a hand is placed close to the globe it produces a faint smell of ozone, as the gas is produced by high voltage interaction with atmospheric oxygen. Some globes have a control knob that varies the amount of power going to the center electrode. What happens if […]
Which describes how a simple machine can make work easier?
Which describes how a simple machine can make work easier? Explain how a machine makes work easier. Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. What are three ways machines make […]
How do you mess up a GPS signal?
How do you mess up a GPS signal? How a GPS jammer works: The user plugs the jammer into the automotive auxiliary power outlet. The unit is placed close to the installed GPS tracker. When active, the GPS jammer generates an interference signal over a 5 to 10 meter radius to disrupt reception of the […]
Which organ is responsible for oxidizing 90% of consumed alcohol?
Which organ is responsible for oxidizing 90% of consumed alcohol? Alcoholic liver disease—As the chief organ responsible for the breakdown of alcohol, the liver is particularly vulnerable to alcohol metabolism’s effects. More than 90 percent of people who drink heavily develop fatty liver, a type of liver disease. Which alcohol is easiest on your liver? […]
Does benzene absorb UV light?
Does benzene absorb UV light? Note that both benzene and naphthacene absorb light in the near ultraviolet but that the latter does so much more intensely. A solution of naphthacene will absorb almost 100 times as much light at 250 nm. as a solution of benzene of the same molar concentration. Can light break bonds? […]
Why H2O is polar and CO2 is nonpolar?
What is the angle of incidence for minimum deviation?
What is the angle of incidence for minimum deviation? Angle of minimum deviation is equal to the angle of prism A of an equilateral glass prism. The angl… An equilateral prism is made of material of refractive index ? 3. What is angle of minimum deviation in prism? The smallest angle through which light is […]
Who devised a commonly used classification system?
Who devised a commonly used classification system? Carl Linnaeus What Three Kingdoms did Linnaeus divide nature? Linnaean taxonomy divides all of nature into three kingdoms: animal, vegetable (or plant), and mineral (The mineral kingdom does not include living organisms, so it is not discussed any further here.). Both plant and animal kingdoms are subdivided into […]
