U doesn't represent anything.
In the English alphabet, each letter is assigned a numerical value based on its position. The letter "U" is the 21st letter in the alphabet. Therefore, the number that corresponds to the letter "U" is 21.
Scientists use the symbol "u" to represent atomic mass unit.
( u(x+h) - u(x) )/ h
because u always need different ways to look at numbers
Avogadro's number is the relation to 1 u with 1 gram in mol so if an atom weighs 12 u (C-12) 1 mol weighs 12 grams and 12 mol is 6.0221415 × 1023 u
U is for uranium
google it u dummy
They both have the same numerical value
no what r u stupid of coarse not

i dont know but u do....
Put the numbers in numerical order, pick the middle number. If there is an even number of numbers, pick the middle two, and find the mean of them. So in this case, the middle two numbers are 4.8, and their mean (4.8+.48 divided by two) is [u][b]4.8[/u][/b]
