The first ∂/∂t term is called V the local derivative. The second ~· ∇ term is called the convective derivative. In steady flows, ∂/∂t =0, and only the convective derivative
The substantial derivative has a physical meaning: the rate of change of a quantity (mass,
energy, momentum) as experienced by an observer that is moving along with the flow. The
observations made by a moving observer are affected by the stationary time-rate-of-change
of the property (∂f/∂t), but what is observed also depends on where the observer goes as
it floats along with the flow (v · ∇f). If the flow takes the observer into a region where, for
example, the local energy is higher, then the observed amount of energy will be higher due
to this change in location. The rate of change from the point of view of an observer floating
along with a flow appears naturally in the equations of change.
What do u mean by chemical or physical reaction... Please give me an answer so i can give you the answer.
Explain the difference between chemical change and physical change, and provide examples of each. Define chemical change and physical change, and provide examples to illustrate. Differentiate between chemical change and physical change, and give examples to clarify the distinction.
no, a physical change
this is my homework just give the answer already!
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
I have a good derivative.
Why: Because that's what the derivative means, the way it is defined - the slope of the curve at any point of the line.
The Federalist Party of Early America favored a loose interpretation of the Constitution.
To get the second derivative of potential energy, you first need to calculate the first derivative of potential energy with respect to the variable of interest. Then, you calculate the derivative of this expression. This second derivative gives you the rate of change of the slope of the potential energy curve, providing insight into the curvature of the potential energy surface.
take out the constant -2 then take the intergral of cosx this will give you sinx your answer is -2sinx
Donate is an English derivative of the Latin for 'to give'. The original Latin verb is 'donare'. The Latin verb literally means 'to give as a present'.
They give a visual interpretation of the data.
What is the main difference between compilation and interpretation? Give an example of languages of compilation and interpretation respectively.
To trace a curve using differential calculus, you use the fact that the first derivative of the function is the slope of the curve, and the second derivative is the slope of the first derivative. What this means is that the zeros (roots) of the first derivative give the extrema (max or min) or an inflection point of the function. Evaluating the first derivative function at either side of the zero will tell you whether it is a min/max or inflection point (i.e. if the first derivative is negative on the left of the zero and positive on the right, then the curve has a negative slope, then a min, then a positive slope). The second derivative will tell you if the curve is concave up or concave down by evaluating if the second derivative function is positive or negative before and after extrema.
To take early and substantial action to keep well clear of the stand on vessel
The English derivative for "laudat" is "laud." It's a fancy way of saying "praise" or "commend." So next time you want to give someone a pat on the back, just say "I laud you" and watch them be impressed by your vocabulary.
There is not enough information to give a meaningful interpretation of this dream.
