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.
True. The term "base weight" is used in comparing atomic weights where the atomic weight of carbon-12 is set as the reference standard with a value of exactly 12 Atomic Mass units. Other elements are compared relative to this standard to determine their atomic weight.
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.
Converting pounds into kilograms is common in scientific measurements and international applications, as kilograms are the standard unit of mass in the International System of Units (SI). It is also useful for comparing weights in a more standardized and widely recognized unit.
Yes, if the weight of the hangers were exactly the same, their contribution to the forces acting on the system could be neglected in the computations. This is because the equal weights would create equal and opposite forces, leading to a balanced system where their effects cancel each other out.
The plumb line experiment involves suspending weights from three points and the intersection of the three lines created by the weights is considered the center of gravity because it represents the point where the total weight of the system acts as if all the weight were concentrated at that point. This is due to the balancing of the torques created by the weights acting on the system.
Temperature at the atomic level is a measure of the average kinetic energy of the particles in a system. It reflects how fast the particles are moving or vibrating.
Yes, if all the weight hangers in an experimental method have the same weights attached, then the weights can be neglected when considering the effect on the overall vector quantity being measured. This is because the weights would exert equal and opposite forces on the system, effectively canceling each other out in terms of their impact on the vector quantity being studied.
The correct expression - after IUPAC rules - is atomic weight.The atomic weight unit is necessary to appreciate the atomic weights of chemical elements.
The atomic mass unit system was devised to accurately describe the mass of atoms and subatomic particles on a consistent scale. It provides a unified standard for expressing relative atomic masses of elements based on the carbon-12 isotope.

The carbon-12 isotope, like all carbon atoms, has 6 electrons. This is because the number of electrons in an atom is equal to its atomic number, which for carbon is 6.
That won't do it.
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.
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
