Answer to: Why do we use the root-mean-square speed instead of the average velocity to describe a gas that follows the kinetic model of gases? By...
In general, you calculate the mean or average of a set of numbers by adding them all up and dividing by how many numbers you have. This can be defined as follows: For a set of numbers, {x1, x2, x3, ... xj} the mean or average is the sum of all "x" divided by "j". ...
Averages typically identify the middle of a set of related values. In this lesson, we will investigate what the mean value theorem for integrals...
and the state that mean VP/VS ratio reflected was that of the upper crust.The moving average value of VP/VS ratio showed continuously low value anomaly both before the M5.4 main shock occurred on Nov.29, 1999 and the M5.0 strong aftershock occurred on Jan.10, 2000.We believe these anoma...
