12 SHORT ANSWER 43. At an electrical generating station, falling water or another source of mechanical energy spins a turbine that, in turn, spins coils of wire located between magnets. When the wire coil rotates near the magnetic poles of the magnets, the negatively charged particles in the wire are forced to move, generating electrical energy. This energy is then distributed to our homes through the electrical energy distribution grid. 44. Answers will vary. Possible answer: In 2007, Ontario was producing 22 % of its electrical energy with renewable energy sources. Hydro-electric generation and wind generation were already being used. I think Ontario should expand on these sources of energy currently being used. We could construct more hydroelectric generating stations and set up additional wind farms. Ontario should also explore other renewable energy sources, such as geothermal generation, photovoltaic generation, and thermal generation using biomass, to determine if any areas of Canada could benefit from these energy sources, as well. 45. Answers will vary. Possible answer: I already try to limit my energy consumption by using the sleep mode on my computer during the day and turning it completely off at night. I also limit my use of electrical energy by unplugging the charger for my cellphone, laptop, and MP3 player as soon as the device is finished charging. In the future, I can further reduce my consumption of electrical energy by using power strips to plug in my television, stereo, and DVD player and turning these strips off when I am not using the devices. I can also turn lights off when I am not in a room, take shorter showers, and switch to energy efficient light bulbs. 46. I would choose the more expensive model, with the Energy Star symbol. This means the product is more energy efficient. Even though the initial cost of the product is $25 more, this amount will quickly be recovered because of the lower cost to operate the dishwasher. Over time, the Energy Star model will actually save me money. 47. The 1600 W dishwasher for $ will cost more in the first year. In addition to the initial charge of $400.00, it will cost $ to run the dishwasher for approximately 2 hours each day for a year. The total cost of this dishwasher in one year is $ The 1200 W dishwasher costs more initially, but the approximate operating costs will be just $87.60 each year. The total cost of this dishwasher for the first year is $ Answers will vary. Possible answer: We would have no lights, no air conditioning or heat, no water, and no television or Internet. Most of the appliances we rely on every day require electricity. Life would be drastically different without all the conveniences dependent upon electricity. 49. Answers will vary. Possible answer: I feel geothermal generation is the best alternative energy source for Ontario. Geothermal energy is always present in the Earth s crust. Geothermal fluids can be reheated and reused, and geothermal generation does not produce pollution or greenhouse gases. Geothermal heat pumps for an individual home or office are inexpensive and reliable. 50. Where it is possible, I think people should produce their own electricity through the use of solar panels or wind turbines. When people produce their own electricity, it reduces the demand on large power plants. It also reduces the amount of wiring and other construction needed because the generating source is at the same location as where the energy is being used. 51. Batteries can be used for smaller devices, such as a wireless mouse or a flashlight. These devices might be able to last several days on the amount of electricity provided by one or two batteries. Larger appliances, such as large televisions, heating and cooling devices, and vacuum cleaners would need far too many batteries to operate. The costs and the inconvenience of changing batteries would make the appliance unusable. 52.

13 The rod contains more electrons than protons; therefore, it is a negatively charged object. The ball contains more protons than electrons, making it a positively charged object. According to the Law of Electric Charges, objects with opposite charges attract each other. The rod and ball will attract each other. 53. The rod and ball both contain more electrons than protons, which means both objects have a negative charge. According to the Law of Electric Charges, objects with like charges repel each other. Therefore, the rod and ball will repel each other. 54. Answers will vary. Possible answer: The Law of Electric Charges states that objects with opposite charges attract each other, while objects with like charges repel each other. To remember the Law of Electric Charges, I remember the saying opposites attract. This reminds me that opposite charges attract, and like charges repel. 55. When you rub your socks across a carpet, electrons from the carpet may move to you. When you then touch a metal doorknob, the electrons can move from you to the doorknob. This is an electric discharge. You feel the shock and you may even see a small spark from the discharge. 56. Before you begin combing, the comb and your hair are both neutral. When your hair and the comb are rubbed together, the atoms in the plastic comb have a greater ability to attract electrons, causing some electrons to move from your hair to the comb. This makes the comb negatively charged and your hair positively charged. Since opposite charges attract, the hair sticks to the comb. 57. When you rub a balloon against your sweater, the contact causes the balloon to become negatively charged. The wall is neutral. When you bring the balloon near the wall, the electrons in the balloon repel the electrons in the wall. This causes some electrons in the wall to move away from the balloon. The part of the wall near the balloon is temporarily charged by induction. The positive charges on the surface of the wall attract the negatively charged balloon.

14 58. Static electricity is an imbalance of electric charge at rest on the surface of an object. Static means not moving. The electric charges stay in one place, until they all at once move to another object. Current electricity also has to do with electric charges, but with current electricity the charges are moving. Electric current is the flow of electricity through a conductor in a closed path. 59. This is a series circuit. The battery is the energy source. The alligator leads and wires are the conductor. The lamps are loads, and the knife switch is the control device This is a parallel circuit. The lamps are arranged so that there is more than one path the electrons could follow Answers will vary. Possible answer: To determine the difference between a series and a parallel circuit, I trace the path electrons would follow, without touching the circuit, starting from the energy source. If I can make it back to the energy source without coming to a branch in the path, I know it is a series circuit. If there is at least one branch, it is a parallel circuit.
