If two materials have the same geometry, and different moduli, they MUST have different stiffness. (a) - True (b) False

A piece of corroded metal alloy plate was found in a submerged ocean vessel. It was estimated that the original area of the plate was 800 cm2 and that approximately 7.6 kg had corroded away during the submersion.

A 5stage single pipeline computer uses the pipeline mentioned in the lecture (not the book). It resolves the direction and target of a conditional branch instruction at the end of its third pipeline stage.

The properties of the air in the inlet section with A1 = 0.25ab m2 in a converging-diverging channel are given as U1 = 25a, b m/s, T1 = 3ab K, P1 = 13a, b kPa (absolute).

A completely reversible heat pump produces heat at a rate of 100 kW to warm a house maintained at 25℃. The exterior air, which is at 0℃, serves as the source.

A closed system undergoes a process in which work is done on the system and the heat transfer Q occurs only at temperature Tb. For each case, determine whether the entropy change of the system is positive, negative, zero, or indeterminate.

A scientist who is evaluating an ancient human skeleton for signs of vitamin and nutrient deficiency is conducting:
