8. Infer: The slope of the line is a measure of the stiffness of the spring. The greater the slope, the stiffer the spring because it indicates more force is required to stretch the spring a given amount. The slope of the line is called the spring constant and given the symbol k. Based on your data, create an equation that relates the force on the spring (F), the displacement (x), and the spring constant (k).

Can anybody me with this? ? (picture included.)

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.
