When something is moving, it is in motion. pressing the gas pedal in a car will put the car in motion. two important properties of motion are speed and direction. speed is how fast an object is moving. if tony and tanya both run at the same speed and in the same direction, and they both run for the same amount of time, what can you say about the distance they travel? a) they will run an equal distance. b) tony will run a greater distance. c) tanya will run a greater distance. d) without knowing the exact speed, you can't say for sure.

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 × 10-6 ω·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 ¢ 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 it’s resistivity when at operating temperature? explain.
