Pregnancy tests measure the level of hcg in your body. When you are pregnant, and as your pregnancy progresses, your hcg level rises. When you take a urine pregnancy test and it comes back negative, the level of hcg is not high enough to register on the test. When the quantitative serum pregnancy test is positive, it is a more acurate reading of how far along in your pregnancy you actually are.
You mean, what happens when positive and negative charges are equal? That is simple, the equal opposite cancel each other out and we have an electrical neutrality
The positive reaction color for simple sugar is orange, by Benedict's solution.
This partice is called atomic nucleus.
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
The passage of direct current through an ionic liquid (either molten OR dissolved in something (often water). The idea is that the current causes the positive AND the negative ions travel in opposite directions - and thus can be separated.
i dunno if this is the answer youre looking for. negative x negative = positive negative x positive = negative positive x positive = positive same thing with dividing integers its really simple.
A simple one would.
Simple math rules state that a negative times a negative equals a positive!
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
Multiplying and dividing integers is real easy. All you have to do is do regular dividing and multiplying keeping in mind these simple rules: RULES: 1: When multiplying or dividing integers, when the numbers are a positive, positive they equal a positive. When the numbers are negative, negative they equal a positive. In other words, same signs equal positive. 2: This rule is very similar to the rule above. The only change is that when the signs are different, they equal a negative. ( negative, positive= negative, positive, negative= negative.) Please correct me if I'm wrong. Multiply integers- my notes from class positive x positive= positive positive x negative= negative negative x negative= positive Divide integers- again my notes from class positive divided by a positive= positive negative divided by a negative= positive negative divided by a positive= negative Dividing integers are simple if the number has a different sign than the other it is always negative but if they have the same sign its always positive ex. -20/5=-4 ex. -20/-4=-5
What is your question?

Depending on colours of course black is usually negative and the other colour (generally red but depends) is positive. Get a D-cell Battery. Now get two pieces of speaker wire. hold one wire on the positive terminal of the battery and hold the other on the negative side of the battery. touch the wires to the positive and negative posts on the speaker. if the cone moves out ward the positive and negative are correct if it moves inward then the positive and negative are reversed (out of phase.) this simple test will allow you to see which terminal is which.

A negative times a negative is a positive. A simple way to remember this is... n * p = n p* n = n p * p = p n * n = p There will always be two negatives, and two positives.
-n+-n=-2n so -1+-1=-2. In simple terms a negative plus a negative eqauls a negative. You can just add the numbers as if they are positive and then add a negative sign to the answer.
