Many people love roller coasters. Some people call them scream machines. They agree that
riding a roller coaster is a thrilling experience. What you may not realize while you are going 60 miles an hour is that a roller coaster has no
engine. You are not being propelled around the track by a motor or pulled by anything. A roller coaster moves on its own. How do you think that
can happen?

The heater element of a 120 v toaster is a 5.4 m length of nichrome wire, whose diameter is 0.48 mm. the resistivity of nichrome at the operating temperature of the toaster is 1.3 Γ 10-6 ΟΒ·m. the toaster is operated at a voltage of 120 v. (a) what is the power drawn by the toaster? (b) if the cost of electricity is 12 Β’ per kilowatt-hour, and it takes 2 minutes to toast bread, how much does it cost for toasted bread? (c) when the heater element is at room temperature, is the resistivity in the nichrome wire greater than, less than, or equal to itβs resistivity when at operating temperature? explain.
