Read the scenario and answer the accompanying questions. Electrical current is the flow of electrons through a wire and is measured in amperes (amps) . The voltage (volts) is a measure of the electric force required to keep electrons flowing through a wire. Power is the rate at which electricity does work, or provides energy, and is measured in watts (W) . The current and voltage are related to electric power by the following equation: Power = volts × amps. Large amount of electric power is measured in kilowatts (kW) . An electric bill reflects the total amount of electrical energy (expressed in kilowatt-hours, kWh) , used by all electric appliances for the duration of the time (in hours) they were being used. Thus: kWh = (W × h) ÷ 1000. -If an electrical tea kettle requires 1500 watts to heat, how many kilowatts does this equal?


A) 1.5 × 103 kw
B) 1,500,000 kw

Read the scenario and answer the accompanying questions. Many important life-sustaining resources and ecosystem services are predicted to become scarcer in the next 50 years. Two of the best-known examples of this trend involve water and oil consumption. Although a daily dependence on both is a fact of human existence in the 21st century, these resources differ in very basic ways: renewability. Although not the only effective approach, increased conservation is recommended as a central focus for managing both resources, in order to accelerate the transition to a more sustainable future. -Increased water stewardship requires that we stop using Earth's surface and groundwater as_______
