5. Given that the ASCII codes for 'A' through 'Z' are x41 through x5A; and the codes for 'a' through 'z' are x61 through x7A: What are the bit-mask and the logic operation (NOT the LC3 instruction) that would force a character stored in R0 to lower case - i. e. convert an upper-case character stored in R0 into lower case, and leave a lower case unchanged (so ‘A’ would become ‘a’, and ‘a’ would remain ‘a’).

Note: the LC-3 stores ASCII characters in the lower ("right-hand") byte of a 16-bit word, with the upper byte set to zero

Consider a power plant with water as the working fluid that operates on an ideal rankine cycle. it has a net power output of 45mw. superheated steam enters the turbine at 7mpa and 500°c (h=3411.4 kj/kg; s=6.8 kj/kg k) and is cooled in the condenser at a pressure of 10 kpa by running cooling water from a lake through the tubes of the condenser at a rate of 2000 kg/s. (a) show the cycle on a t-s diagram (a right schematic is fine - you do not need to calculate the temperatures at each point); (b)-determine the work done by the turbine and the pump in kj/kg; (c)-the mass flow rate of water used by the power plant; (d)-the thermal efficiency of the cycle; (e)-the temperature rise of the cooling water. assume the cooling water is incompressible with cp 4.18 kj/kg°c.
