A) A gram of TNT has about 2700 Joules/gram of chemical potential energy which can be released. A chocolate chip cookie has about 21,000 joules/gram of chemical potential energy. Discuss why we use TNT in mining operations and not chocolate chip cookies. B) A single square meter of area at the Earth’s surface gets about 1 kilowatt of power from solar energy. ( About 400 Watts can be harvested using electric solar cells.) Given that currently the average power usage...

Energy consumption is measured in units of kilowatt hours (kWh). The more kWh a household use in a month, the higher the energy bill. A power company charges customers $0.12 per kWh for the first 500 kWh. After the first 500 kWh, the rate is $0.15 per kWh. Write a program to calculate energy charge. You must write and use the following two functions. (a) A main function: Ask the user to enter number of kWh used. Call the bill_calculator...
