In articles and discussions, we reviewed the many failings (in terms of both reliability and validity) of projective tests. But let’s not throw out all these tests; there are specific scoring methods/indices for projective tests that have some supportive evidence. Nonetheless, improved methods still tend to fail to help the validity of these tests in clinical practice because:

Extra credit quiz questions will ask you to break down each essay into the component pieces that need to be answered.  In quizzes, you are NOT required to actually answer any of the essay to earn the extra credit.  Worth up to 2 points.   Chapter 9 Meiosis, essay 3 For meiosis, using the proper terminology, describe how to start with 1 mother cell to end up with the appropriate number of daughter cells.  Your answer should use the proper terminology, compare the mother cell and the daughter cells, discuss the needed cellular structures and mention the amount of DNA in cells throughout the process.  You are allowed to draw out the stages of meiosis to help yourself but your answer will be graded on the written explanation of meiosis.

A brave stunt devil would like to recreate one of Evil Knievel’s famous jumps, launching himself and his bike across line of trucks which are arranged side by side, each of which is roughly 2.6 m wide. Strangely, he decides to do this by using a very stiff springboard, which is originally compressed by 1.5 m, to push the bike up a ramp which is inclined at an angle of 23° and is 3.0 m long from the edge of the springboard (see figure). Ignoring the effects of air resistance, suppose the stunt devil would like to jump 25 trucks, needing to reach a speed of about 30 m/s by the edge of the ramp.   a)  If the stunt devil and the bike have a combined mass of 160 kg, what must the spring constant of the springboard be in order for the stunt devil to make the jump if the ramp is effectively frictionless? b)  What total work must be done on the stunt devil for him to make the jump? Which forces do work as he moves along the ramp? c)  Suppose the ramp does provide a small frictional force on the tires of the bike, doing -3,000 J of work on the stunt devil as he reaches the edge of the ramp. By how much further should the spring be compressed for the stunt devil to safely make the jump? d)  If the springboard of part c) is in contact with the stunt devil for about 1.8 s, what average Power does the spring deliver to the stunt devil?

Lightning McQueen rounds a curve of radius 80 m which is banked so that cars traveling at 100 km/hr (27.8 m/s) can safely take the curve even in the absence of friction. The coefficient of static friction between Lightning McQueen’s tires and the road is 0.72.     a)   Draw a FBD of Lightning McQueen as he rounds the curve, assuming he does so without slipping. b)   At what angle is the curve banked?  c)   What is the maximum speed with which Lightning McQueen can take the curve without skidding?

Two ladybugs land on a vinyl record of radius R = 15 cm which is initially at rest.  The first ladybug lands halfway from the center of the disc, while the other lands on its edge as shown below. The disc then begins to rotate, speeding up with an angular acceleration given by

When a rigid object rotates about a fixed axis, what is true about all the points in the object?

An piece of space debris is released from rest at an altitude that is two earth radii from the center of the earth. Compared to its weight on Earth, the weight of this debris is
