Which statement best describes how the distance from a large river affects an area’s climate in the summer? Regions far from rivers experience less variation in air temperatures.
Regions far from rivers have land surfaces that remain cool during the entire season.
Regions near rivers have water surfaces that rapidly change in temperature from cold to hot.
Regions near rivers experience winds from the water that prevent extreme temperature changes.

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.
