True. The unit for the atomic weights of chemical elements is the relative Atomic Mass unit (1/12 from the atomic mass of the isotope 12C).
Note that atomic weights is used for elements and atomic mass for isotopes.
The answer is false because the base of weight is not a system of comparing atomic weights and second false answer is that it is not carbon it is hydrogen.
True, I found that out on Yahoo.
comparing between pcm system and analog system : power , B.W , SNR , transmission length ?
It is not accurate to call the electricity being produce 'carbon free' because for the transaction to work parts of carbon dioxide are being pumped into the system.
The first law of thermodynamics states that the energy of an isolated system is constant.
If the combustion is incomplete, carbon monoxide can be formed. Other than that, if you are in an enclosed space, carbon dioxide could be dangerous. Also, if a fire occurs, that could also be dangerous.
On such a system, you get to have 2 sets of "holes". One on the side of the aircraft, independent of the air flow, that measures the present atmospheric pressure. Comparing this pressure (static) with the ground one (given by the Airport Tower for a given area), gives you your altitude. The second "hole" (or set of holes) is in the front of the aircraft (usually the nose or close to the cockpit) and it has a membrane inside a tube that is pressed by the increased airflow created by the aircraft's speed. Comparing this pressure (pitot-tube pressure), with the fore-mentioned static one, gives you the aircraft's speed.
The correct expression - after IUPAC rules - is atomic weight.The atomic weight unit is necessary to appreciate the atomic weights of chemical elements.

That won't do it.
There are six electrons in a carbon atom, the isotope does not change this.
Carbon is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent-making four electrons available to form covalent chemical bonds. noizyoyster.com
Yes.
No they are not.
you can lift the same weights on a cable system as with free weights (usually). the difference is that free weights are able to target specific muscles where are with cables you don't really have this option (it is sort of possible but not as effective). a cable system is good for a beginner as it allows you to use stabilising muscles and is less likely to cause injury.
Yes.
