Homework Answers
It is not possible to create any kind of energy no matter what resources you have. It is not yet clear how the energy already existing in the universe was created, but all observations in nature tell us that energy can not be created or destroyed, only transferred. For example, work is a way of transferring energy into a system by applying force during a certain distance; mechanical waves transfer energy by propagating a disturbance through a medium; heat transfers energy through a temperature difference between two or more regions in space. Dark energy is a hypothesis that tries to explain why the universe expands in an accelerated way and it is not yet clear what its nature is and how it really affects the matter that forms the universe.

The first law of thermodynamics states that energy can neither be created nor destroyed. How then is it possible for ∆E to be anything other than zero? In other words, what do we mean when we call a physical scenario “non-conservative” if energy must, by nature, be conserved?

The first law of thermodynamics teaches us the conservation of energy, which means the energy can be neither created nor destroyed. However, if you listen to the Public Radio, read Wall Street Journal or watch CNN, you can always learn that we are in the global shortage of energy. Is the First Law of Thermodynamics violated?

Part A State the law of conservation of energy The law of conservation of energy states that energy can neither be created or destroyed. Energy can be transferred from one object to another, and it can assume different forms. The law of conservation of energy states that energy can not be created but it can be destroyed. Energy can be transferred from one object to another can be destroyed in a chemical reaction, and it can assumo different forms The...

Q9. Can matter be created or destroyed? Yes, it can be created. Yes, it can be destroyed. No, matter is always conserved Q10. In a reaction, 25 grams of reactant AB breaks down into 10 grams of product A and an unknown amount of product B. Using the law of conservation of mass, how much does product B weigh? Explain how you got your answer?

Part (a) "Companies create value for their owners by investing cash now to generate more cash in the future. The amount of value created is the difference between investments made and cash inflows -- adjusted for the fact that tomorrow's cash flows are worth less than today's, due to the time value of money and riskiness of future flows.
