1. How much energy will it take to melt a block of ice of mass 15 kg? If this same energy was used to lift the ice, to what height (in meters) could it be raised?
show all work please
2. What wavelenght of electromagnetic radiation would you expect from a radio station operating at 120 MHz?
3. If only conductive heat loss was significant for a house, then by what percentage would you lower the heat loss if the temperature was reduced inside from 70 degrees Farienheit to 60 degrees farienheit, when the outside temperature is 20F?
