Uniformity coefficient of soil is always less than 1?
The uniformity coefficient (Cu) of soil is a measure of the particle size distribution, defined as the ratio of the size of the 60th percentile of the grain size distribution to the size of the 10th percentile. For a well-graded soil, Cu is greater than 1, indicating a range of particle sizes, while a uniform soil with similar particle sizes will have a Cu value close to 1. Therefore, the statement that the uniformity coefficient of soil is always less than 1 is incorrect; it can be equal to 1 or greater than 1 depending on the soil's grading.
On what parameters do the coefficient of restitution depend?
The coefficient of restitution depends on several parameters, including the materials involved in the collision, their surface properties, and the conditions of the impact, such as speed and angle. It reflects the elasticity of the collision, where elastic collisions have a coefficient of 1 (maximum energy conservation) and inelastic collisions have a coefficient less than 1. Additionally, temperature and the presence of any external forces can also influence the value of the coefficient.
How do you express a number in scientific?
To express a number in scientific notation, you write it as the product of a coefficient and a power of ten. The coefficient should be a number greater than or equal to 1 and less than 10, while the exponent indicates how many places to move the decimal point. For example, the number 4,500 can be expressed as (4.5 \times 10^3). If the number is less than 1, the exponent will be negative, such as 0.0045 written as (4.5 \times 10^{-3}).
What is efficiency always less than?
It is always less than 1 or 100%.It is always less than 1 or 100%.It is always less than 1 or 100%.It is always less than 1 or 100%.
Is 0.34 greater or less than 1?
0.34 is less than 1. In numerical terms, any positive number less than 1 will have a decimal value that is smaller than 1. Therefore, 0.34, being a decimal less than 1, is indeed less than 1.
What numbers will a correlation coefficient not ever be?
34.32245Correlation coefficient is less than -1 and greater than 1.Note: The Correlation coefficient is lies between -1 to 1 if it is 0 mean there is no correlation between them.
What type of force does low coefficient belong to?
Friction has a low coefficient, usually less than 1.
Is -012 a negative correlation?
No. A correlation coefficient cannot be less than -1 (or greater than +1)
What is the correlation coefficient of -2?
A serious error. The maximum magnitude for a correlation coefficient is 1.The Correlation coefficient is lies between -1 to 1 if it is 0 mean there is no correlation between them. Here they are given less than -1 value so it is not a value of correlation coefficient.
When using scientific notation the the coefficient is less than what?
When using scientific notation, the coefficient must be between greater than or equal to 1, and less than 10. For example, 5.17, 9.63, and 1.49 are all correct coefficients, while 0.12 and 10.87 are not.
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.
Why vane coefficient is always less than 1?
It isnt, for deflection angles b less than 90o, Cvane should be greater than 1.0, while for angles greater than 90o, it should be less than 1. Alot of times it is less then one because it is the ratio between the actual force and ideal force. Factual/Fideal. Since friction acts on the actual force, it is going to be less then the ideal force, resulting in a number lower than one.
The coefficient of friction is always?
The coefficient of friction is not always constant as it can vary depending on factors like materials in contact, surface roughness, and presence of lubricants.
Uniformity coefficient of soil is always less than 1?

Therefore, the statement that the uniformity coefficient of soil is always less than 1 is incorrect; it can be equal to 1 or greater than 1 depending on the soil's grading.
Can a correlation coefficient be greater than 1?
No.

What is the phenol coefficient?
The phenol coefficient is a measure used to evaluate the disinfecting power of a chemical compared to phenol. It is determined by comparing the dilution of a test compound that achieves a specific level of microbial kill to that of phenol under identical conditions. A phenol coefficient greater than 1 indicates that the test compound is more effective than phenol, while a coefficient less than 1 indicates lower effectiveness. This metric helps in assessing the potency of disinfectants in microbiological applications.
