Solar cells harness the sun's energy and convert it into electricity. However, the cost of this clean energy is much higher than
Dafna11 [192]

Answer:<u> Option D </u>

Solar panels contain a very expensive element, i.e. silicon. This element is able to convert the solar energy into electric energy. The cost of the solar panel gets expensive because of this rare element. It is found in limited areas of the world. That’s why option D is correct. Coal is not used in solar panel, so option B is incorrect. Neither is wind energy, so option A is also incorrect. Water is also not used for exploiting solar energy, which makes option C a wrong answer.

Under certain circumstances, potassium ions ( K + ) in a cell will move across the cell membrane from the inside to the outside.
dexar [7]

Answer:

8.18 × 10 ⁻²¹.

Explanation:

The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.

The change in the potential energy can be calculated as follows:

W = v2-v1 × q.

Here, the charge of the proton is considered because k+ ions has been used.

W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.

W= 8.18 × 10 ⁻²¹J.

Thus, the answer is 8.18 × 10 ⁻²¹.
