In a study, participants were asked to evaluate two contradictory theories. If they preferred one theory and subsequently favored evidence that supported it while dismissing evidence against it, this is an example of: 

What is the greatest number of unique keys a perfect B+ Tree with n=3, l=40 and height=2 (has levels 0, 1, 2) can have (Assume unique values are inserted)? Assume 0 based height. A tree with a single root node has a height = 0. n = maximum children a node can have l = maximum keys a leaf node can have

10 Points A toy gun uses a spring with a force constant of 300 N/m to propel a 10.0-g steel ball. If the spring is compressed 7.00 cm and friction is negligible: How much force is needed to compress the spring? To what maximum height can the ball be shot? What is the gun’s maximum range on level ground?

You are a Doctor of Nursing Practice student analyzing the sleep patterns of college students by calculating the number of hours of sleep. You ask the participants to fill out a tool with a Likert-type scale which does not provide any clinical intervention.  What type of study is this? 

In a survey, participants are asked if they support a “90% success rate” versus a “10% failure rate” for a medical procedure. This illustrates:

10 Points The graph shows the force exerted on a tennis ball (mass = 58 grams) as it is in contact with a tennis racquet moving in the positive direction.  What is the final velocity of the ball if it was moving in the negative direction at a speed of 42 m/s.
