Which of the following statements about lung compliance (CL) are true? CL is calculated as Δ Vol / flow. Normal CL is 100 mL/cmH2O. Stiffer lungs will have a lower CL. Increased CL causes the patient to breathe rapid and shallow.

Explain what “residual stresses” are?

What is weathering steel?

Each drawing shows three points along the path of a projectile, one on its way up, one at the top, and one on its way down. The launch point is on the left in each drawing. Which drawing correctly represents the acceleration a→{“version”:”1.1″,”math”:”a→”} of the projectile at these three points?

A 60 kg post-op patient is receiving mechanical ventilation in the ICU. ABG results and related data are:Mode: SIMV-VC                                   FiO2:    50                 PS:   5 cmH2O Mandatory Rate: 10 bpm                       Vt:  500 mL Total Rate:  10 bpm                               Insp Flow:  50 Lpm                   ABG:  pH 7.31/ PaCO2 61/ PaO2 88/ HCO3 26 Which of these ventilator adjustments would correct the PaCO2 in this patient?

A certain object is in equilibrium. Which one of the following statements is not true?

Two forces act on a 16-kg object. The first force has a magnitude of 68 N and is directed 24° north of east. The second force is 32 N, 48° north of west. What is the acceleration of the object resulting from the application of these two forces to the object?

Which strategy is used to minimize the risk of atelectrauma in patients with low compliance?

Two cars are traveling at the same constant speed v. As the drawing indicates, car A is moving along a straight section of the road, while car B is rounding a circular turn. Which statement is true about the accelerations of the cars?
