(b) potential difference is rejected - a better analogy for p.d. is generally pressure, force or height difference. Potential difference is just a mangled, contracted form of “difference in electrical …

You should probably go through each type of intermolecular force, and see if it is there. The order of precedence for each type of intermolecular force is: hydrogen bond permanent dipole-dipole …

However it is a special case where the bottom number (denominator) is fixed at 100. Often you will see the symbol % used. This is just like a unit of measurement but one that is worth …

This question highlights an important difference between math and physics. In physics, we change our models to match reality. If our models say that a ball should float up into the air, …

Jun 7, 2018 · Which answer is simplified and has the appropriate restrictions for the variables x^2-25/x-5?

Using the range approximation, our estimate for the standard deviation is s~~1.67. The range approximation says, "the standard deviation s for a data set is roughly proportional to the …

-5 Set up the expression: The quotient is the division: -90/9 = -10 Subtraction is the difference (note the negative number): -10 - (-5) = -10 + 5 = -5

The electron volt (eV) is a unit of energy equal to approximately 1.6×10−19 joule (J). By definition, it is the amount of energy gained (or lost) by the charge of a single electron moved across an …

Now for the tricky part. When chemists report an elemental analysis and it adds up to less than 100%, the difference is generally attributed to oxygen. Our analytical methods, constrained by …

No difference. In a reactive circuit which consists of Resistance, Inductance and Capacitance there is net lead or lag between the applied voltage of frequency omega and the total current …
