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.

A woman consumes 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day. how many total kcalories has s
DedPeter [7]
To calculate the energy offered from food, multiply the number of grams of protein, carbohydrate, and fat by 4, 4, and 9, respectively.
Then add the results together.

Given: 500 grams of carbohydrates, 30 grams of protein, and 75 grams of fat in one day.

500 grams x 4 kcal/g = 2000 kcal
30 grams x 4 kcal/g = 120 kcal
75 grams x 9 kcal/g = 675 kcal
= 2795 kcal

From this data, you can calculate the percentage of k calories each of the energy nutrients give to the total.
Solution:

2000/2795 * 100% = 72% from carbohydrates
120/2795 * 100% = 4% from protein
675/2795 * 100% = 24% from fat
Total: 100%
