superconductor.
No , coefficient of friction can not be zero. if it is zero then there will be no frictional force between two bodies.And in our universe these types of object didnot exit.
Yes, every material with a temperature above absolute zero emits electromagnetic waves, also known as thermal radiation. The intensity and wavelength of the radiation depend on the temperature of the material, as described by Planck's law.
No, the coefficient of friction cannot be zero because some level of resistance is always present when two surfaces come into contact with each other.
At absolute zero temperature, semiconductors behave as insulators because all energy levels are occupied and no electrons are able to move through the material. As temperature increases, electrons are excited to higher energy levels, allowing them to conduct electricity. This behavior is described by the semiconductor's band structure and can be manipulated by introducing impurities or applying an electric field.
Yes, carbon has a negative temperature coefficient. -0.5*10^3/C
Porcelain is an insulator, its resistance approximates infinity.
positive
The temperature at which the second virial coefficient of a real gas is zero is known as the Boyle temperature. At this temperature, the real gas behaves ideally according to the van der Waals equation of state.
A correlation coefficient of zero means that two things are not correlated to each other.
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
use the T=2a/(bk) equation shown in the first link, plugging in a and b values found in the second link. proofs are shown in the joule-thomson expansion wikipedia page as well as the van der waals equation of state page.
A perfect insulator has infinite ohms of resistance.
if coefficient of skewness is zero then distribution is symmetric or zero skewed.
A swamping resistor is usually manufactured from the metal alloy manganin (trade name), or other alloy with similar resistance/temperature characteristics -i.e. practically zero temperature coefficient of resistance. In other words, its resistance will remain more-or-less constant over a wide range of temperature variation.
superconductor.
A coefficient of zero means there is no correlation between two variables. A coefficient of -1 indicates strong negative correlation, while +1 suggests strong positive correlation.
