After a retropubic prostatectomy, a patient needs continuous bladder irrigation. The patient has an IV of D5W infusing at 150 ml/hr, and a triple-lumen urinary catheter with normal saline infusing at 200 ml/hr. The nurses empties the urinary catheter drainage bag three times during an 12-hour period for a total of 3580 ml. How many milliliters does the nurse calculate as urine?

The diagrams show six different arrangements of a box attached to a massless spring on a frictionless surface. The spring constant and mass of the box are shown in the diagrams. The rightmost vertical dashed line shows the position of the right edge of the box when the spring is neither compressed, nor stretched. The boxes are then pushed to compress the spring by the amount shown, and then let go. At that time, the boxes start oscillating back and forth. Rank the periods of oscillation for each box.

A block with mass = 10,000 kg is attached to a massless spring with a spring constant = 25 N/m. At time = 0 s, the block is observed to be 100 cm to the left of the equilibrium position and moving toward the left with a speed of 12 cm/s. What is the position of the object at = 175 s?

A turntable (thin disk) has a mass of 2.0 kg and radius of 0.15 m. It is initially spinning with angular frequency of 15 rad/s. A 0.50 kg mass is dropped onto its rim and sticks. Find the angular frequency (in rad/s units) after the mass is stuck on the rim.

When Preeti fusses at their local grocery store, her dad gives her a treat so she will stop fussing. After a while, she fusses more at at their local grocery store because her father has ‘rewarded’ her fussing with treats. This explanation is most compatible with a ________ approach.
