Two short problems confirm whether or not these solutions are correct without the use of AI) A sheet of insulation is 3.5 cm thick and has a thermal conductivity of 0.13 W/m·K. The warm side of the insulation is 305 Kelvin, and the cool side of the insulation is 292 Kelvin. Determine the rate of heat per unit area that travels from the warm side to the cool side of the insulation. Specify your answer to 1 decimal place and in units of W/m². Note that your answer should be a positive number. ANS ( 48.3 W/m^2) & Consider a rigid tank that contains refrigerant 134a. The refrigerant 134a has a temperature of -20°C and a quality of 0.46. Determine the specific internal energy of the refrigerant 134a. Specify your answer to 2 decimal places and in units of kJ/kg. ANS (119.03 KJ/Kg)

Suppose an individual invests $24,000 in a load mutual fund for two years. The load fee entails an up-front commission charge of 2.8 percent of the amount invested and is deducted from the original funds invested. In addition, annual fund operating expenses (or 12b-1 fees) are 0.59 percent. The annual fees are charged on the average net asset value invested in the fund and are recorded at the end of each year. Investments in the fund return 7 percent each year paid on the last day of the year. If the investor reinvests the annual returns paid on the investment, calculate the annual return on the mutual funds over the two-year investment period. (Do not round intermediate calculations. Round your answer to 2 decimal places. (e.g., 32.16)) Annual return %
