Answer:
The correct answer is the imperial system.
Explanation:
Only three countries in the world, that is, the United States, Myanmar, and Liberia use the imperial system. These include measurements in the form of inches, ounces, Fahrenheit, and feet. In the imperial system, the distances, height, weight, or area measurements are used eventually that traced back to everyday items or parts of the body.
In comparison to other metric systems, the units used in the imperial system are not further differentiated easily into parts of hundreds or thousands, and are thus, regarded of less use in comparison to other metric systems by some. The real follower of the imperial system at present in the world is the United States.
Answer: Concentration of the dye in solution is 1.159 M
Explanation:
According to Beer-Lambert law, the absorbance is directly proportional to the concentration of an absorbing species.
Formula used :
where,
A = absorbance of solution = 1.657
C = concentration of solution = ?
l = length of the cell = 0.701 cm
= molar absorptivity of this solution =
Thus the concentration of the dye in solution is 1.159 M
<span>Energy is absorbed and then released to form an emission line.
When electrons absorb energy they increase there energy level. This is only temporary and the excited electron then relaxes back down to its original energy level releasing energy.
The energy is released in form of EM radiation of a specific frequency depending on the element and how many energy levels the electron relaxes.
This forms an emission line.</span><span />
