<span>Multiplexing is the process of combining numerous signal of data or sound on to a single carrier like an optical fiber by using different wavelengths. The type of multiplexing that is defined by wavelength instead of frequency is CWDM which is also known as Coarse Wavelength Division Multiplexing.</span>

Answer:
D. Friction and air resistance created heat on his trip up the hill.
Explanation:
Energy transformation from one form to another is not 100% efficient. This is the postulate of the first law of thermodynamics.
Most of the energy transformation is not purely 100%.
When energy is transformed, some are usually wasted.
- In this case, in moving from bottom up, Superman produced some heat and encountered air resistance.
- To reach the top, he must have overcome the resistance and produce enough heat to power him through.
- This reduces the amount of potential energy that should have been the same as the kinetic energy down below.
