you are asked to compare the price of energy in the form of gas or electricity. Please follow the following steps: Get latest copies of your electric and gas bill. If you don’t pay for it, or if you are using all electric appliances, get copies from a friend or family. What is the price you pay for electricity in kWh? Ignore all taxes and other supplemental fees. What is the price you pay for gas in therms? per cubic foot? One therm is 100,000 Btus. Calculate costs of $ per million Btu for both electricity and gas. Which one is more expensive? Why? From the energy efficiency point of view, which appliances make sense to operate with electricity? With gas? Assume that all your energy needs come from electricity. How much more (or less) would you have to pay? Which of the energy forms (electricity from fossil fuels, gas, or solar electricity) are most appropriate (energy efficient) to Operate a radio Run an air conditioner Use for home water heating Use for cooking oven Operate an elevator Weld

Write a MATLAB function named numberWords() that takes a whole number as an argument and returns a string containing the number word for the whole numbers 0 - 999.

For example:  numberWords(234) would return 'two hundred thirty-four'

If the input value is not a whole number between 0 - 999 then the function should return a string equivalent to 'ERROR'.

c) Define the measurement system specifications to meet the above application requirements

d) Develop a feasible design: draw the measurement system block diagram and describe the function of all needed subsystems
