Suppose r = 0x2000,0000 and r1 = 0x12345678. All bytes in memory are initialized to Ox00.

STR r1, [ro], #4
STR r1, [ro, #8]!
STR r1, [ro]

Assume the computer uses Little Endian to store data.
What is the value of register R0 after the program completes: Assume the computer uses Little Endian to store data. Show the memory content when the above program completes successfully.

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature

Compute the pressure drop of 30°c air flowing with a mean velocity of 8 m/s in a circular sheet-metal duct 300 mm in diameter and 15 m long. use a friction factor, f 0.02, and pair = 1.1644 kg/m a. 37.26 pa b. 25.27 pa n c. 29.34 pa d. 30.52 pa

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
