This picture shows a region where a flat plain meets a mountain. Two wildfires, A and B, just started in two different locations, If the wind is consistantly blowing from the west to the east, which fire will burn a greater amount of area in the next 12 hours? Wildfire A
Wildfire B
Both fires will spread at the same rate.

Explain your answer.

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
