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

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Fluids at rest possess no flow energy. a)- true b)- false

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
