Is nuclear power bad for the environment? “Nuclear energy has perhaps the lowest impact on the environment — including air, land, water, and wildlife — of any energy source. It produces no harmful greenhouse gases, isolates its waste from the environment, and requires less area to produce the same amount of electricity as other sources. […]
How did Pangea split?
How did Pangea split? Scientists believe that Pangea broke apart for the same reason that the plates are moving today. The movement is caused by the convection currents that roll over in the upper zone of the mantle. About 200 million years ago Pangaea broke into two new continents Laurasia and Gondwanaland. Which era did […]
What is the formula for calculating electrical load?
What is the formula for calculating electrical load? Compare the wattage of your air conditioner and furnace. Since you only use one at a time, add only the larger wattage rating to your equation. Divide the resulting number of watts by volts (most homes use 220 volts) to get the number of amps, or the […]
Which brand of AA battery lasts the longest?
Which brand of AA battery lasts the longest? Energizer Ultimate Lithium Can I use AA batteries instead of AAA? All the same voltage, so all can substitute for each other. Larger cells just sag less and last longer. Do 18650 batteries explode? The safety problem of 18650 lithium-ion battery is burning or even exploding. The […]
Why does frequency affect wavelength?
Why does frequency affect wavelength? The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. […]
Is it OK to take 2 rest days in a row?
Why do we reject the null hypothesis when the p-value is small?
Why do we reject the null hypothesis when the p-value is small? A p-value less than 0.05 (typically ≤ 0.05) is statistically significant. It indicates strong evidence against the null hypothesis, as there is less than a 5% probability the null is correct (and the results are random). Therefore, we reject the null hypothesis, and […]
What are beats give the theory of beats derive the expression for beat frequency?
What are beats give the theory of beats derive the expression for beat frequency? The beat frequency is equal to the complete value of the alteration in the frequency of the two waves. The count of beats per second is equivalent to the difference in frequencies of two waves is called beat frequency….Beat Frequency Formula: […]
