Answer: Energy of a mole of these photons is
Explanation:
The relationship between wavelength and energy of the wave for 1 mole follows the equation:
E= energy
N= avogadros number =
= wavelength of the wave =
h = Planck's constant =
c = speed of light =
Thus the energy of a mole of these photons is
The efficiency of the process is 42%
From the question given above, the following data were obtained:
Useful energy = 250 watt
Wasteful energy = 600 watt
<h3>Efficiency =? </h3>
The efficiency of the process can be obtained as illustrated below:
<h3>Efficiency = 42%</h3>
Therefore, the efficiency of the process is 42%

The universe is made of a lot of galaxies. The likely explanation for a galaxy having more than one nucleus is that the galaxy must have swallowed several smaller galaxies that were its neighbors.
- There are some reason behind the theory that the eating up of a galaxy is by another galaxy. The galaxy is said to have a powerful past due to the fact that a lot of smaller galaxies were eaten up.
The universe is known to have a very largest galaxy called the giant elliptical galaxy that is made up of about a trillion stars.
