One must have at least two visual pigments to distinguish between wavelengths independent of light intensity.
A substance that converts light energy into electrical potentials is called a visual pigment.
The basic structure of pigment consists of the chromophore, a colored molecule, and a protein called rhodopsin.
There are three types of visual pigments: Scotopsin, rhodopsins, and photopsin.
Scotopsin pigments are associated with vision and operate in less bright light while photopsin operates in a brighter light.
However, visual pigments are very significant substances as they are associated with vision and play a vital role in detecting light.

Answer:
Eh = 21 [J]
Removed as heat.
Explanation:
This is a case of energy conservation, we have to take into account the energies that go in and out of the system. In this case, 135 [J] of energy are entered in the form of work of the compressor to the chamber where the refrigerant is compressed, now of these 135 [J] 114 [J] were used as internal energy, this internal energy is used to increase the pressure and temperature of the refrigerant.
In this way the rest of the energy of the 135 [J] was lost in the form of heat to determine this loss of energy, we simply perform the arithmetic subtraction.
Eh = 135 - 114 = 21 [J]
Eh = 21 [J]
The formula for orbital speed v is v=(G*Me/r)^1/2
Wher G= 6.67E-11, Me= 6E24, r= Re+h= 6.4E6+740000
putting values in the formula we get
v= 7486.7 m/s or v= 7.4867 km/s
