Answer:
25%
Explanation:
If there is 20% scrap, then
80% of (production + scrap) = 72 pcs/hr
Now,
The percent increase in labor productivity is, .
Or it can be written as 25% of which would give 80 pieces per hour.
Changing the number of electrons changes the <em>net electric charge</em> of the atom.
If the atom was originally neutral, then it becomes an <em>ion</em> . (If it wasn't originally neutral, then it was already an ion.)
The wave height is equal to twice the amplitude of the wave.
The wave height of a wave of given wave with amplitude, period and wavelength is equal to twice the amplitude of the wave.
The amplitude of a wave is the maximum displacement of the wave, starting from the zero position of the wave. The wave height measures twice the maximum displacement of the wave.
Thus, we can conclude that the wave height is equal to twice the amplitude of the wave.
