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

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?

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?
