Can a coefficient of friction be equal to zero?
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.
What happens to the particles when the matter freezes?
This would depend on the freezing temperature of the material, and therefore, also on the type of material in question. At absolute zero, a theoretical temperature, all motion of the particles stops.
How does an increase or decrease in temperature affect density?
Usually, an increase in temperature will result in a decrease in density, and vice versa. (There are exceptions, but they are very rare.)The amount by which this happens is the coefficient of thermal expansion. If it doesn't happen (like for borosilicate glass, used for test tubes) the coefficient is zero. If it works backwards (higher density with higher temperature, like water between 32-40 degrees F), the coefficient is negative.
What phase of matter has particles that do not move?
There is no phase of matter that has particles that do not move UNLESS the material is a SOLID at a temperature of ABSOLUTE ZERO.
What is the lowest coefficient to friction?
It can never be exactly zero, but it is close to 0.
Does carbon have a nearly zero temperature coefficient of resistance?
Yes, carbon has a negative temperature coefficient. -0.5*10^3/C
Does porcelain have a nearly zero temperature coefficient of resistance?
Porcelain is an insulator, its resistance approximates infinity.
What is the temperature coefficient of an extrinsic semiconductor is?
positive
What is the temperature called at which the second virial coefficient of a real gas is zero?
Boyle temperature
A correlation coefficient of zero indicates?
A correlation coefficient of zero means that two things are not correlated to each other.
Is it possible for a coefficient of variation of a set of data to be zero Explain.?
Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
Is resistivity of a conductor temperature dependent?
A perfect insulator has infinite ohms of resistance.
Can a coefficient of friction be equal to zero?
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.
Which of the material is used for the swamping resistance that is connected in series with the working coil of a voltmeter?
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.
If coefficient of skewness equals 0 then what would you say about the skewness of the distribution?
if coefficient of skewness is zero then distribution is symmetric or zero skewed.
What does a correlation coefficient of zero indicates?
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.
What is the zero lift drag coefficient of Airbus A330-200?
coefficient of drag in 0 lift
