Given: a variable named incompletes that refers to a list of student ids, and a variable student_id Write some code that counts the number of times the value associated with student_id appears in the list associated with incompletes and assigns this value to number_of_incompletes. You may use, if you wish, an additional variable, k. You may use only k, incompletes, student_id, and number_of_incompletes.

One kg of ammonia in a piston-cylinder assembly, initially saturated liquid at 5 bar, is boiled at constant pressure to saturated vapor. Kinetic and potential energy changes are negligible. a) evaluate the heat transfer [Btu] for this process; b) calculate the entropy production [kJ/K] for this process assuming that the heat transfer occurs with a heat reservoir at 277.28 K. c) Explain on a thermodynamic basis why this process reversible, irreversible or impossible; d) show the states and process on P-v and T-s diagrams.

An average person generates heat at a rate of 84 W while resting. Assuming one-quarter of this heat is lost from the head and disregarding radiation, determine the average surface temperature of the head when it is not covered and is subjected to winds at 10°C and 29 km/h. The head can be approximated as a 0.2-m-diameter sphere. Assume a surface temperature of 15ºC for evaluation of μs. The properties of air at 1 atm pressure and the free stream temperature of 10°C are k

You built an android that has a subcircuit containing a power supply, a tactile sensor, and a fuse where safe operation should keep current below 250 mA. You measured that your sensor is dissipating 12 W, the power supply is pro - viding 12.2 W, and the voltage drop across the fuse is 500 mV. Is your circuit properly protected?
