- You are considering purchasing a compact washing machine, and you have the following information: • The Energy Guide claims an estimated yearly electricity use of 350 kW-hrs, based on 8 loads of laundry being washed per week. • The Energy Guide claims an estimated yearly operating cost of $38. This estimate is based on $0.1065 per kW-hr, and eight loads of laundry being washed per week. • Local electricity costs $0.086 per kW-hr. • You wash four loads of laundry per week. Based on this information, first calculate the energy that would be used by this compact washing machine in a year. Then calculate the yearly energy cost. $3.27 $15.34 $19.00 $178.40Can you remove adsorbed water by oven drying at 105°C, explain.Suppose you were to build a bridge in the state of Texas.
