The point of origin of an epileptic seizure is called the ____.â
djyliett [7]
The point of origin of an epileptic seizure is called the focus. It is the part of the brain that is affected by epilepsy. This is a term used for people with partial epilepsy. The focus can be the frontal lobe, occipital lobe, mesial temporal lobe or the parietal lobe. During seizures, it is the that specific part of the brain that is being effected.  Seizures happen when a surge in the electrical activities happen on certain parts. Symptoms are contractions of the muscles, blackouts and visual disturbances. Seizures can be cured and, for partial epilepsy, they are treated with AEDs or antiepileptic drugs.

vovangra [49]

The normal force decreases, this is the frictional force. It will be counteracted by the force which accelerates the brick to slide downward opposite to the end where the board is raised. As the angle increases the force acting upon the brick opposite to the normal force will decrease.

coldgirl [10]
Refer to the diagram shown.

Given:
h(n,e) = 1500 + 75n + 50e

Define 
\hat{r} = unit \, vector \, along \, \vec{v} \\ \hat{i} = unit \, vector \, east \\ \hat{j} = unit \, vector \, north \\ \nabla \equiv \hat{i}  \frac{\partial}{\partial e} + \hat{j}  \frac{\partial}{\partial n}

\hat{r} =  \frac{1}{ \sqrt{2} } (-\hat{i}+\hat{j} )

Then the rate of change of h with respect to the vector v is
\nabla h . \hat{r} = \frac{1}{\sqrt{2}}(50\hat{i} + 75\hat{j}).(-\hat{i}+\hat{j}) = \frac{1}{\sqrt{2}} (-50+75) =17.68

Answer: 17.7 ft per mile
