On the ARM7TDMI, if the stack pointer (SP) holds the address 0x1000 and you executed the following instruction:

STMDB SP!, {LR, r3, r9, r7, r2}

what addresses now hold the values previously held in:

a. Link Register (LR)?
register r3?
c. register r9?
d. register r7?
e. register r2?

f. What is the stack policy used here

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.
