Soil is important for life. without soil many plants that we depend on for food and oxygen would not grow. the amount of water that can be absorbed by soil for use by plants and animals is determined by the texture of the soil.

what determines the texture of soil?

a) ph
b) amount of air
c) particle size
d) permeability

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.
