How do you calculate coefficient of linear expansion of copper?
dL/dT = αL*L, where L is the length of the steel, T is temperature, and αL is the linear thermal expansion coefficient which for steel is about 11.0 to 13.0. That is possibly the easiest differential equation in history: (1/L)dL = (αL)dT ln(L) = αLT L = eαLT
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
Formula for bulk modulus of volume of elasticity?
K(bulk modulus of elasticity)=-{[Pressure x volume]/change in volume}
What is the effect of temperature on hall coefficient of a lightly doped semiconductor?
hall coefficient of a lightly doped semiconductor will decrease with increase in temp as hall coefficient is inversely proportional to number density of charge carriers.
What is the difference between positive and negative temperature coefficient of resistance?
Negative temperature coefficient of resistance means that as the temperature of a piece of wire or a strip of semiconducting material increases, the electrical resistance of that material decreases.
What if income-elasticity coefficient is negative?
an elasticity of coefficient of -1 means what
What does it mean if the price elasticity of demand is 2?
It's an elasticity coefficient of demand: deltaD/deltaP When the coefficient is >1 it is an elastic demand When the coefficient is <1 it is a nonelastic demand
Coefficient of a materials elasticity?
Youngs Modulus
What is the coefficient of elasticity?
The coefficient of elasticity, often referred to as the price elasticity of demand or supply, measures the responsiveness of quantity demanded or supplied to a change in price. It is calculated as the percentage change in quantity divided by the percentage change in price. A coefficient greater than 1 indicates elasticity (demand or supply is responsive to price changes), while a coefficient less than 1 indicates inelasticity (less responsive). A coefficient of exactly 1 signifies unit elasticity, where changes in price lead to proportional changes in quantity.
What is the coefficient of a material's elasticity called?
Young's Modulus
What is the coefficient of a materials elasticity?
Young's modulus
What is the dimension of modulus of elasticity?
the dimensions of Young's Modulus of Elasticity = (M).(L)^(-1).(T)^(-2)
A cross elasticity of demand coefficient of plus 2.5 indicates that the two products are substitutes?
True or False: A cross elasticity of demand coefficient of +2.5 indicates that the two products are substitutes.
Coefficient of elasticity how many types?
As many types as variables are used to calculate the elasticity. Elasticity is simply a relationship between rates of change of variables in equations.
If a demand for a product is elastic the value of the price elasticity coefficient is?
greater than one
Are two goods complements if the cross-elasticity coefficient is negative?
Cross Elasticity Coefficient is defined as when the price of a particular commodity rises how is the demand of another commodity changing. If the goods are complements like say for example petrol and petrol driven cars, if there is a price hike in petrol then demand for petrol cars would fall. Hence a negative cross elasticity of coefficient. On the other hand the demand for deisel cars would rise (given the deisel prices are constant) because they serve as substitutes, and will have a positive cross elasticity.
What is the importance of coefficient of variation?
It's a way of obtaining a measure of dispersion that is dimension-free.
