How would you use Tectonic plate and hot spot in the same sentence

Sonbull [250]

It's kinda long but...
A tectonic setting where volcanic action occurs is called a hot-spot (intraplate), which describes volcanic activity that occurs within tectonic plates and is generally NOT related to plate boundaries and plate movements.
Hope this helps!!:)

Consider a vortex filament of strength Γ in the shape of a closed circular loop of radius R. Consider also a straight line throu

Sedbober [7]

Answer:

$\vec{V} = \frac{\Gamma}{2R}\vec{A}$

Explanation:

We define our values according to the text,

R= Radius

$\vec{V} =$ Velocity

$\Gamma =$ Strenght of the vortex filament

From this and in a vectorial way we express an elemental lenght of this filmaent as $\vec{dl}$ . So,

$\vec{dl}x\vec{r} = R*dl*\vec{A}$

Where $\vec{A}$ imply a vector acting perpendicular to both vectors.

Applying Biot-Savart law, we have,

$\vec{V} =\frac{\Gamma}{4\pi}\int\frac{\vec{dl}x\vec{r}}{r^3}$

Substituting the preoviusly equation obtained,

$\vec{V} = \frac{\Gamma}{4\pi}\int\frac{R*dl*\vec{A}}{R^3}$

$\vec{V} = \frac{\Gamma}{4\pi R^2}\int^{2\pi R}_0 dl*\vec{A}$

$\vec{V} = \frac{\Gamma(2\pi R \vec{A})}{4\pi R^2}$

So we can express the velocity induced is,

$\vec{V} = \frac{\Gamma}{2R}\vec{A}$

alexira [117]

Answer: Voltage

Voltage is the measure of force or potential energy that required moving a unit charge from one location to another through a conductor. This potential energy is stored in the form of an electric charge imbalance and capable of provoking electrons to flow in material through which charges can easily flow.
