What is the difference between hall-effect in metals and semiconductor?
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.
Which two surfaces would have the highest cofficient of friction?
Two rough surfaces with high friction coefficients would have the highest coefficient of friction. For example, rubber on concrete or sandpaper on wood would typically result in a high coefficient of friction due to the roughness of the surfaces.
What does Cofficient of friction mean?
The coefficient of friction is a measure of the resistance to motion between two surfaces in contact. It quantifies the force required to overcome the frictional resistance between the surfaces. It is a dimensionless value that ranges from 0 (perfectly slippery) to 1 (highly resistant to motion).
What is meant by the cofficient of linear and superficial expansion?
The coefficient of linear expansion measures how much a material expands in length when heated, while the coefficient of superficial expansion measures how much a material expands in area when heated. Both coefficients are used to quantify how materials respond to changes in temperature.
Why are alloys constantan and Manganin used to make standard resistors?
Constantan and Manganin have low temperature coefficients of resistance, meaning their resistance remains relatively stable over a wide range of temperatures. This makes them ideal for use in standard resistors where a consistent and precise resistance value is required. Additionally, both alloys have high resistivity, which allows for the creation of resistors with higher resistance values in a compact size.
Properties of correlation cofficient?
why correlation cofficient always lies between 1 and -1
What is the 5 in 5n called?
That 5 is the cofficient of the term. The "n" is the variable!
What is cofficient in term 5x?
5x 5 is the coefficient and x is the variable.
What is the co efficient for window grill painting?
cofficient of window 1mx1m
Does the cofficient of linear expansion depend on length?
No, it is a fundamental mechanical property of the material
What is the meaning of the algebra term cofficient?
In the equation 2x = 6 the coefficent of x is 2
Jet as an application of Bernoulli's equation?
determine the equation for trajectory with ahead of 7.0m and velocity cofficient of .95
What does cofficients mean?
a cofficient is a numder placed in front of a chemical formula in an equation.d luck good luck!
Which one of the following method serve to measure correlation bw two variable?
cofficient of rank correlation
What is temperature cofficient in pn junction?
Temperature coefficient of the PN intersection voltage to balance the temperature coefficient of the warm voltage.
What happen to the value of cofficient if unit of measurement changed from gm to kg?
To convert from gram to kg, you need to divide by 1000.
What is the cofficient of performance in the refrigeration system?
Coefficient of performance, or COP, is defined differently for heating and cooling applications. For heating: COP=(heat supplied + work)/work For cooling: COP=(heat removed)/work Work in this case refers to the compressor and other motors.
