Look at the size of the 'flags' inside the LED lens itself. The bigger one is the positive one. Don't ask me about a bi/tri colour LED, maybe with a capacitor.
Yes. If both parents have the recessive gene for Rh negative, a child of theirs could have Rh negative blood. I have two daughters who are Aneg, and both of us are A+.
If what are both negative?
yes because you either get your parent's traits, the opposite traits, or a little of both but because both parents are positive the child could be positive OR negative
The location of UXOs, both positive and negative Post-attach findings like the presence of contamination
Not necessarily. They could both be positive.
Because when you are looking for the hypothenuse, it will be bigger than both the numbers so it length will be in positives, and when you are looking for side a or b, it won't work with a negative because a negative and a positive will cause the number to be smaller.
no, he has at least one - but the other half could be + or - if baby is -- then both parents gave - meaning they both are one of these +- or --
An integer has both positive and negative numbers.

There's no general rule. The result could be positive and it could also be negative. It depends on how big both numbers are. (neg 5) minus (neg 7) = pos 2 (neg 5) minus (neg 3) = neg 2
speed is a scalar quantity with magnitude only but no direction; velocity is a vector with both magnitude (speed) AND direction, which could be positive or negative
Yes. It can also be negative in the numerator. Both positive and negative numbers (as well as zero) can be rational numbers. Both positive and negative numbers can be irrational numbers. Both positive and negative numbers (as well as zero) can be integers.
