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.

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.
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 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%
Where possible identify the variable numerical coefficient and constant in each expression 7a-8?
15
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.
What is a possible leading coefficient and degree for a polynomial starting in quadrant 3 and ending in quadrant 4?
Leading coefficient: Negative. Order: Any even integer.
Where is it not possible to use correlation?
It is not possible to use correlation when the two variables are not related at all. the corelation coefficient value that will be obtained will have no significance.
What is the highest modulation coefficient and percent modulation possible with a conventional AM system without causing excessive distortion?
the highest modulation coefficient is one (1) and percent modulation is 100
Can the greatest common factor ever be smaller than the smallest coefficient?
No. The smallest coefficient possible is 1, and the smallest GCF is also 1. You cannot have a common factor of zero.
What is it called when there are many different kinds of things around you?
Diversity is what describes the many different kinds of things that surround us. One of the opposites is uniformity. In uniformity, as many people and things look alike as possible. There's little choice in the kinds of people and things.
