The following two masses are attached by a rope that goes over an ideal pulley, as shown. If we use the typical coordinate system where to the right is +x and up is +y, the acceleration constraint in this system is

A 70 kg woman stands on a scale in an elevator. The elevator was moving upwards with speed 5 m/s but begins to slow down to stop at the next floor with acceleration magnitude 1 m/s2. What force is displayed by the scale as it is slowing down? You can take g = 10 m/s2.  

A mass M is suspended from a massless, inextensible rope which is attached to three massless, frictionless pulleys as indicated in the figure. The rope is anchored in a wall on the right and pulled with a force F on the left. What is the acceleration experienced by the mass? (note that positive acceleration is defined as being in the direction indicated by the upwards arrow)  

A balls rolls off a vertical cliff, falling from an initial height H above a flat valley below. The ball is initially traveling horizontally with a speed of 10 m/s when it rolls off the edge of the cliff. When the ball lands on the valley below, it strikes the ground 20 m away from the edge of the bottom of the vertical cliff. What is the height H of the cliff above the lower valley? Take g = 10 m/s2

Your idea to change the appeal from “green” to “other guests” is based on the _______________ influence tactic.

Series of questions around your experience

Answer the following questions.   The explanatory variable is [1] and the response variable is [2].   The scatter plot shows a [3] trend between the two variables.   In linear regression analysis, we first check the variability of the [4] variable.   An estimate for an adult man’s arm-span with the height of 70 inches is [6] inches.

The nurse is caring for a patient who is confused. The nurse speaks with a patient care assistant (PCA) about toileting the patient. The nurse knows the PCA understands the toileting procedure when the PCA makes which of the following statements?

A 19-year-old started on fluoxetine 10 days ago reports increased agitation and insomnia. She denies suicidal ideation. What is the most appropriate clinical consideration?  

A vital component of PMHNP practice is evidence-based care requiring critical appraisal of literature and then translating this evidence into practice.  As a PMHNP you read about a case study where a combination of multivitamins and herbal products resulted in a patient going into remission from depression. Based on your knowledge of levels of evidence what would be your action related to this case study?
