Is it always possible to determine the coefficient of uniformity and coefficient of curvature for all types of soils?
Determining the Coefficient of Uniformity (Cu) and Coefficient of Curvature (Cc) only has meaning when classifying coarse-grained soils, i.e. clean gravels (GW or GP) and clean sands (SW or SP) having more than 50% of material larger than No. 200 sieve with less than 5% fines. Gravels and sands with more than 12% fines (GM, GC, SM, SC) are distinguished using Atterberg limits. There would be no reason to determine these coefficients for fine-grained soils (i.e. clay, silt and peat).

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.

a karyotype
Coefficient of thermal expansion of water at 300C?
This can be found from the steam tables. www.x-eng.com gives steam tables. At different temperatures and pressures wolume of water can be found. To find the coefficient of expansion of water, find the volume at 5degree lower and 5 degree higher at same pressure. Take the mean and divide with the volume of water at desired temperature. Cross check the calculation for which you have the answer. I have used the way and works well. The coefficient of expansion of water changes rapidly with temperature at constant pressure.
Why must the stack pointer be initialized at the beginning of every program?
Because the stack pointer marks the top of the stack. If it is not initialised, it is not possible to determine where the next stack frame will go.
What factors determine the induced voltage of a dc machine?
i think that it is possible that for unknown circumstances i don't know it.
When this equation is balanced what is the coefficient for Ni NO3 3?
The coefficient for Ni(NO3)2 in the balanced equation depends on the overall reaction. Without knowing the full equation, it is not possible to determine the coefficient for Ni(NO3)2.
Is it possible for a coefficient of variation to be negative?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
Is it possible for the coefficient of friction to have a negative value?
Yes, it is possible for the coefficient of friction to have a negative value in certain situations, such as when dealing with lubricated surfaces or materials with unique properties.
Is it possible for a coefficient of variation to be negative Explain.?
Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.
What is the possible range of values for the coefficient of variation?
0% to 100%
How do you calculate friction equals coefficient of friction X normal force when frictional force and coefficient force are variables not given?
If both the frictional force and coefficient of friction are variable and not given, it is not possible to calculate the friction force using the equation friction = coefficient of friction x normal force. The relationship between these variables would need to be explicitly provided in order to determine the friction force.

Is it possible to obtain a correlation coefficient of 1.5 for two sets of test scores?
No. Correlation coefficient is measured from +1 to -1. In addition, if the two sets of exam are exactly same, their correlation coefficient is +1.
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 it possible for the coefficient of friction to exceed 1 in a given scenario?
Yes, it is possible for the coefficient of friction to exceed 1 in a given scenario. This can happen when the force required to move an object is greater than the force pressing the object against the surface, resulting in a coefficient of friction greater than 1.
Is it possible for the coefficient of static friction to exceed 1?
Yes, it is possible for the coefficient of static friction to exceed 1. This means that the force required to overcome static friction is greater than the force pressing the surfaces together.
What is a possible leading coefficient and degree for a polynomial starting in quadrant 3 and ending in quadrant 4?
