find the angle of the resultant vector for the vectors shown below. (nearest whole number and angles measured from the positive x-axis)
vector
a) 39 degrees
b) 51 degrees
c) 70 degrees

Explanation:

In order to find the resultant of the two vectors, we need to find the components of each vector along the x- and y- axis.

For the horizontal vector, we have:

x-component:

y-component:

For the vectors of 18 units:

x-component:

y-component:

So the components of the resultant vector are

And so the direction is given by

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
