Use the table to the right answer the following question. Item Energy released by burning 1 kg of a certain combustible sedimentary rock Energy (joules) 1.6x 10" 5.6x 1013 7x 10 2x 10 How many kilograms of isotope would be required to supply the energy needs of country B for 1 year? Energy released by fission of 1 kg of a certain isotope Energy released by fusion of hydrogen in 1 liter of water Country A annual energy consumption Country B annual energy consumption 3x 10 It would take approximately kilograms. (Use scientific notation. Use the multiplication symbol in the math palette as needed. Round three decimal places as needed.)
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
