What is the most slippery metal?
What is the most slippery metal? In fact, the low static coefficient of fric- tion of Teflon-on-Teflon, 0.04, made it the most slippery solid substance on earth. Further experimentation revealed the reasons for these properties: the carbon backbone of the polymer chain was com- pletely surrounded by fluorine atoms. Why is friction less on snow […]
What process occurs in stellar explosion?
What process occurs in stellar explosion? Stellar nucleosynthesis is the creation (nucleosynthesis) of chemical elements by nuclear fusion reactions within stars. The term supernova nucleosynthesis is used to describe the creation of elements during the explosion of a massive star or white dwarf. What is the difference between the two types of supernovae? A type […]
What are the four large units of geologic time called?
What are the four large units of geologic time called? The largest unit of geologic unit of time is an eon. Geologic time is divided into four eons: the Hadean eon, the Archean eon, the Proterozoic eon, and the Phanerozoic eon. The first three eons are part of a time interval commonly known as Precambrian […]
What happens to inductor when switch is closed?
What happens to inductor when switch is closed? When the switch is first closed, the current through the inductor is zero, because it cannot change instantaneously. This means that the inductor acts like an open circuit, so all the voltage is across the inductor. The changing magnetic field creates a back emf which acts to […]
Can airbags kill you?
Can airbags kill you? Not only can the airbag can seriously injure you, it can kill you. Second and third generation airbags, even though, they have been de-powered from the mid 1990’s, still deploy outward at 300 mph. A deploying airbag has the explosive equivalent of 20 shotgun shells. This can cause neck fractures and […]
What are the three main physical properties of sound waves?
What are the three main physical properties of sound waves? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. […]
What are the three types of accumulators?
What are the three types of accumulators? Depending on separating elements, we can distinguish three types of hydraulic accumulators: bladder accumulators, diaphragm accumulators, and piston accumulators. What is the purpose of accumulator? Accumulator is a pressure vessel for storing hydraulic pressure in it utilizing compressible and decompressible nature of nitrogen gas. So, it can be […]
