Which of the following statements about photovoltaic cells is true? Select all correct answers a. They are not vet commercially viable b. They use mirrors to focus sunlight on a tube carrying a heat transfer fluid. c. They produce electricity directly from sunlight. d. They do not require connection to the electric gridExplanation / Answer
10- C
growing crops specifically for biofuel production would result in the reduced food production, because the quality of the soil get deteriorated and become inviable of production of the food product,
11. C
the pesticide treadmill refers to the use of pesticide is incresed in the soil without their use no further good yeild is achieved they always need to require the pesticide otherwise the crop gets influenced.
12. C
geothermnal energy is the only energy that requires sun energy, in the earth the suns energy gets stored and this stored energy in the earth is known as geothermal energy.
13 B, C
photovoltaic cells are the solar cell that we are using is on a high extent now a days and it is economically viable, and they also require grid-connected PV power system is an electricity generating solar PV power system that is connected to the electric grid, yes they produce electricity directly from sun light, and mirrors are used to focus the sunlight onto a tube. The tube contains a fluid that is heated by the sunlight and then used to heat a traditional power cycle.
