A 100-megawatt (MW) coal-fired power plant has an efficiency of 40%. Assume a heating value of approximately 7.5 megajoules per kilogram (MJ/kg) for coal.
(a) Estimate the daily consumption of coal burned in this plant to generate electricity
(b) Estimate the equivalent amount of natural gas (heating value= 14 MJ/kg) required to generate the same amount of electricity.
(c) How many 2MW wind turbines would be required to replace the coal power plant?
(d) Each wind turbine costs $3 million, and coal costs $0.15/kg. If you replace the coal power plant with the wind farm, how many kilograms of coal will not be burned (calculate this based on cost, not demand)

The starship enterprise is caught in a time warp and spock is forced to use the primitive techniques of the 20th century to determine the specific heat capacity of an unknown mineral. the 125-g sample was heated to 96.3°c and placed into a calorimeter containing 85.9 g of water at 20.0°c. the heat capacity of the calorimeter was 14.2 j/k. the final temperature in the calorimeter was 24.5°c. what is the specific heat capacity (in j/g°c) of the mineral? enter to 4 decimal places.
