ok heres a small question... sorry if it sound stupid =\
say u have two parallel conductors, current flowing in the same way and the magnetic field going into the page [look at attachment]
if u use the right hand palm rule the two forces dont appear to attract ?
in the textbooks they...
Here is wot i have jotted down for the "recent discoveries of elements" dotpoint :
Recent discoveries of elements
During and after World War II an American team, led by Glenn Seaborg created 10 new elements in an accelerator including neptunium, the first element heavier than uranium, and...
some1 explain to me why the anode is called the negative electrode
as the anode is the area of oxidation [loss of electrons] and since electrons are negatively charged why do we call the anode the negative electrode?
thx!!!
mm accidentalyl deleted teh question
it was "if odd polynomials (not DEGREE) and even polynomials have a root, "a" another root mst be -a"
(unless its a = 0)
When a polynomial P(x) is divided by x-@, the remainder is a<sup>2</sup> and when divided by x-b, the remainder is b<sup>2</sup>. Show that when P(x) is divided by (x-@)(x-b), the remainder is (@+b)x-@b
test points between the roots
then u kno where it is positive or negative
then look at the type of root : linear root - > passes x axis
double - > touches x axis and comes back up / down again
triple - > horizontal point of inflexion
yup then make like p(x)/a(x) = q(x) + r(x)/a(x)
then q(x) will be yer non vertical asymptote (usin limits)
this is when the degree of num > degree of denom
