A negative temperature coefficient indicates that the dependent variable, the variable of interest increases when the temperature decreases and conversely. This could, for example, be the density of an object (excluding water at 0 - 4 deg C). As the temperature goes up the volume increases so the density decreases.
5x 5 is the coefficient and x is the variable.
No, it is a fundamental mechanical property of the material
negative numbers> temperature.
In the equation 2x = 6 the coefficent of x is 2
no because the only way degrees can be negative is in temperature.
Temperature coefficient of the PN intersection voltage to balance the temperature coefficient of the warm voltage.
Well, there's typically two types of materials-Those with positive temperature coefficient and those with negative temperature coefficient. Positive temperature coefficient are those whose resistance increases as temperature increases. Negative temperature cofficient are those whose resistance decrease when the temperature increase. There are however some alloys such as Manganin& Constantan whose resistance is not affected by temperature
why correlation cofficient always lies between 1 and -1
That 5 is the cofficient of the term. The "n" is the variable!
No, according to the laws of thermodynamics, it is not possible to achieve a negative Kelvin temperature because it would imply an object has negative energy. The concept of negative temperature in the Kelvin scale does not exist.
negative 'temperature coefficient of reactivity'
5x 5 is the coefficient and x is the variable.
No, it is a fundamental mechanical property of the material
cofficient of window 1mx1m
because we have hall cofficient =1/ne. where the n=no of electron ,e=charge of electron. we know that "n "in metal is very large. so that R=HALL COFFICIENT" is very small FOR it .so we can not find sufficient result for hall cofficient so we use semi conductor which gives non zero hall cofficient.
negative numbers> temperature.
-5 is lower
