1.) Natural gas is the most abundant fossil fuel in the world. a. True b. False
If fossil fuels,such as coal,are still forming today,why are they considered nonrenewable resources? A. We are depleting fossil fuels much faster than they form B. Fossil fuels are broken down by processes faster than they form C. The fossil fuels being formed today are deep under the ocean, where they cannot be reached D. The only fossil fuels being produced are from methane, which we do not have the technology to use yet.
Thinking Nuclear Power is a perfect example of exponential relations. Canada produces over half of its electricity using nuclear reactors. One of the major problems associated with nuclear power generation is the radioactive waste. Currently all nuclear waste is stored on site at the power plant and there is no solution for the long term waste. After completing this Grade 11 Functions and Applications course, you have been put in charge of Energy Production in Canada. A) What would you do with the long term waste? B) How would you take care of Canada's energy needs for the future?
Uranium-238 (U-238) has a half-life of 4.5 billion years. Geologists find a rock containing a mixture of U-238 and lead, and determine that 82% of the original U-238 remains; the other 18% has decayed into lead. How old is the rock? a.) The rock is _______ billion years old.
5. A fossil contains 50% of the carbon-14 it once had as a living creature. Use the half-life decay equation to determine when the creature died. The half-life of carbon-14 is 5730 years.
When we use petrol we are ultimately using stored energy from the sun. Plants capture the energy when growing, and then through a long process of decay and compression this plant matter is converted into a fossil fuel. An interesting question is how much sunlight is needed to produce a quantity of petrol. To estimate this, let's assume the petrol has come from wood, and let's assume we have a fast-growing wood source such as Pinus radiata. Assume also: a mature tree contains around 3 m3 of timber; a tree is harvested when 35 years old; the density of wood is around 500 kg/m3; 2 kg of wood makes 1L of petrol; a tree receives on average 8 hours of sunlight per day. How many "hours of sunlight" are stored in 1L of petrol? i.e. how many hours of sunlight does a tree need to be exposed to, to produce the amount of wood needed to make 1 L of petrol? Give your answer to two significant figures.
(a) Use of hydrogen fusion to supply energy is a dream that may be realized in the next century. Fusion would be a relatively clean and almost limitless supply of energy, as can be seen from Table 7.1. To illustrate this, calculate how many years the present energy needs of the world could be supplied by one millionth of the oceans' hydrogen fusion energy. (b) How does this time compare with historically significant events, such as the duration of stable economic systems?
2. What are nuclear fusion and fission processes? Explain the release of energy in these processes.
8. The half-life of certain type of carbon used for carbon-dating is 5730 years. Determine the age of a bone if it now contains 38 percent of the original amount of carbon. A = 4,(0.5)*
14. sources are those that are depleted by consumption, over human time scales. Examples are fossil fuel and nuclear power.
Wind farms in Washington have a capacity of 3075 Megawatts (mega means million remember so this is 3075000000 watts). This means if they were all operating at the same time this is how many Joules per second they would produce. a) Assume all wind farms in Washington are operating at capacity. How much energy in Kwh is produced in one hour? b) Now it is not windy all the time, so suppose only 60% of the wind farms are operating. How much energy is produced in a 7 day week by these wind farms c) An average home uses about 250 KWh for a 7 day week. How many homes can be operated by the wind farms in part b
Energy in coal comes from the energy stored by that lived hundreds of millions of years ago. A2 a) only animals b) plants & animals both c) only plants d) none of these How much change in the power of wind will take place if blade length becomes 2 times?
