For the MIPS assembly above, assume that the registers $s0, $s1, $s2, and $s3 contain the values 0x0000000a, 0x00000014, 0x0000001e, and 0x00000028, respectively. Also, assume that register $s6 contains the value 0x00000100, and that memory contains the following values:

Address Value
0x00000100 0x00000064
0x00000104 0x000000c8
0x00000108 0x0000012c

Find the value of $s0 at the end of the assembly code.

To save energy, the air supply to a 2000 ft office has been shut off overnight and the room temperature has dropped to 40°f. in the morning, the thermostat is reset to 70°f and warm air at 120 f begins to flov in at 200ft'/min. the air is well mixed within the room, and an equal mass flow of air at room temperature (changing with time) is withdrawn through a return duct. the air pressure is nearly 1 atm everywhere. ignoring heat transfer with the surroundings and kinetic and potential energy effects, estimate how long it takes for the room temperature to reach 70°f. plot the room temperature as a function of time.
