When a fossil fuel is burned energy is converted to kinetic energy answers com? Burning fossil fuels turns potential energy into kinetic energy. Kinetic energy is energy in motion, which can be used to do work. What are the energy transformations in a power plant? 9 explain the energy transformations that occur within a nuclear […]

Will Y2K happen again? When the year 10000 (Y10k) rolls around, we’ll have the Y2K problem all over again when we try to subtract 9000 from 0000. If 8,000 years is too far in the future, don’t worry! There’s another giant date bug that’s right around the corner in 2038. Why are Unix Programmer’s concerned […]

What is the SI unit of charge and current? Coulomb. The coulomb is the SI unit of charge. The size of a coulomb is derived from the ampere. One coulomb is defined as the amount of charge flowing when the current is 1 ampere. What is the SI unit of charge define it? The coulomb […]

What major events happened during the Triassic period? The start of the Triassic period (and the Mesozoic era) was a desolate time in Earth’s history. Something—a bout of violent volcanic eruptions, climate change, or perhaps a fatal run-in with a comet or asteroid—had triggered the extinction of more than 90 percent of Earth’s species. What […]

What is the difference between lone pair and bonding pair electrons? The difference between bond pair and lone pair is that a bond pair is composed of two electrons that are in a bond whereas a lone pair is composed of two electrons that are not in a bond. What is the Vsepr theory of […]

What is Hall effect and its derivation? Hall effect is defined as the production of a voltage difference across an electrical conductor which is transverse to an electric current and with respect to an applied magnetic field it is perpendicular to the current. Edwin Hall discovered this effect in the year 1879. Which of the […]

What was the Long March quizlet? The Long March was when Mao and his 100,000 followers fled to Guomindang and they trekked 6,000 miles and they faced daily attacks. Out of the 100,000 followers only 20,000 survived. You just studied 3 terms! How did the Communists benefit from the long march quizlet? How did the […]

How hard is it to push a car uphill? If you have a winch or a tow-strap (and a friend to pull your car with said tow-strap) then you’d be in business, but pushing any car up an incline in the dry is virtually impossible (it takes effort to move a car even on a […]

What is primary frequency response? Primary Frequency Response are actions to arrest and stabilize frequency in response to frequency deviations. Primary Response comes from generator governor response, load response (motors) and other devices that provide immediate response based on local (device- level) control. What is primary frequency control? – The Primary Frequency Control (PFC), an […]

Is y equal to dy dx? Yes, as long as x is the variable you are differentiating with respect to. For example, if your function is y = 3x 2 + 5x, then both y′ and dy/dx refer to the derivative of this function with respect to x, which is 6x + 5. What is […]
