2. A materials opposition to the flow of electric charge. This is because a current is the flow and so an electrical current will be the flow of an electric charge.
the second one is equal and opposite

Explanation:
Accordingly, any attempt to determine where the helium market will be more than a few years ... and/or recover helium can reduce the amount of helium consumed by as much as a factor ...
Answer:
Average atomic mass = 24.3051 amu
Explanation:
Average Atomic Mass = (Mass of Isotope 1 x Fractional Abundance of Isotope 1) + (Mass of Isotope 2 x Fractional Abundance of Isotope 2) + ......
For 24 Mg
Mass = 23.985 amu
Fractional Abundance = 0.7899
Mass * Fractional Abundance = 18.9458
For 25 Mg
Mass = 24.986 amu
Fractional Abundance = 0.10
Mass * Fractional Abundance = 2.4986
For 26 Mg
Mass = 25.983
Fractional Abundance = 0.1101
Mass * Fractional Abundance = 2.8607
Average atomic mass = 24 Mg + 25 Mg + 26 Mg
Average atomic mass = 18.9458 + 2.4986 + 2.8607
Average atomic mass = 24.3051 amu
Answer:
Option C is false statement. The half life of a second order reaction is not dependent on concentration.
Explanation:
Half life of a reaction is defined as the amount of time which is required for a reactant concentration reduced by half comparison to its initial concentration.
Half life of a second order reaction is depend on the initial concentration of a reaction, in contrast to 1st order reaction.
