Question
The purple graph on the last two pages here depicts power generated (that is, produced, or input to the school) from solar cells installed at Boulder High School. (This is actual data.) The vertical axis is the power axis. The range is 0-100 kilowatts (kW). The horizontal axis is the time axis. The domain is from 12 AM September 20, 2017, until 12 AM September 23, 2017. Each of the big green ticks on the time axis represents 12 AM, midnight, of the day in question. Here are the questions you need to answer. For any questions requiring Riemann sums, please use rectangles of baselength one hour. Be consistent in your choice of points within each subinterval: use left endpoints, right endpoints, or midpoints, but don't mix and match. You should draw in your own, evenly spaced, tick marks on your time axis, between the big green ones provided for you.Explanation / Answer
Power(watt) = Energy (joules) / Time (seconds)
Power*Time=Energy(joules)
Hence the area under the curve represents energy. Units of this quantity is joules.
