Part 1. MATLAB Programming The wind chill
factor measures how cold it feels with a given air temperature T
(in degrees Fahrenheit) and wind speed (V, in miles per hour). The
formula is approximately
WCF = 35.7 + 0.6T ? 35.7(V0.16) + 0.43T(V0.16)
a). Write a function that will calculate the wind chill factor
(WCF) given temperature and wind speed. Your function should round
down to the nearest integer.
b). Write a script that will use the function above to create a
table of wind chill factors, similar to the one shown at
https://en.wikipedia.org/wiki/Wind_chill#/media/File:Wind_chill.png.
Wind speed should be down the left and temperature across the
top.
Please show output if possible Thanks

Solar electricity cost.
Despite all the advantages of using solar cells to harvest solar energy, solar electricity still has an insignificant share (~1%) in the world’s overall energy supply picture. This is mostly due to the economic consideration. While there’s virtually no fuel (sunlight) cost and maintenance cost once the solar panels are installed, the initial cost of solar electricity systems is still the obstacle for wide-spread adoption of solar photovoltaic technologies.
a. Use the single-crystalline Si solar panels as an example. Typical module fabrication cost is $150/m2, and typical efficiency is 15% (the commercial panel efficiency is significantly lower than the efficiency of champion laboratory cell; why?). Calculate the cost of the solar panels in terms of $ per peak power output ($/WP). [Hint: what is the optical power intensity for AM1.5 global spectrum?]
b. Assume all the other cost items (transportation, installation, and other Balance of Systems such as inverters, meters, etc.) is about 150% of the panel cost. A typical panel lifetime is 25 years. In Gainesville, we get about 2000 hours per year sunlight at standard AM1.5G power (1 kW/m2). Calculate, over the lifespan of the solar panels, how much is the cost of the solar electricity in terms of cents per kWh.
