weight is the force by which earth attracts a body towards its centre. so if a body is at centre, is its weight zero because its now not being attracted towards anything.

or is its weight maximum, because the value of 'g' is inversely realted to the distance from radius of the earth 'R'??

swathed into the atmosphere leaving pure oxygen and a rain of carbon dust? Would this be a nuclear reaction? What is the chemistry behind stripping a carbon atom from two oxygens...the machine that does it or the mechanism could be run around the clock in many locations possibly removing 10 billion tons of carbon dioxide a day quite efficiently as the carbon dioxide would be split into o2 and carbon instanly...seems that gas chemsitry holds the answer - what do you think will get us there?

18 / 2 x 3 = ?

Depending on what operation you do first, you come up with either 27 or 3 as the answer.

Using PEMDAS literally, multiplication would come first, but I believe that multiplication and division can be interchangeable.

What is the correct answer and why?????
