Ryan & Patrick (2001) studied four dimensions of the classroom social environment that they believe influence feeing of relatedness in a middle school classroom. Name and define each and offer an example of how you might employ each in your classroom as a teacher. (Please number each item)

Vector A , on the x-y plane, has a magnitude of [a] unit and points in the direction of [angle] degrees measured counterclockwise direction from +x axis. Vector B has components of Bx= [bx], By = [by], Bz= [bz].  Find their dot product A • B ?   

The position of an object is given by x=([A] m/s3)t3 + ([B] m/s2)t2 +([C] m/s)t + [D] m/s. What is the instantaneous acceleration (in m/s2) of the object when t=[t] s?  

A child runs off a [h]-m high dock horizontally and splashes into pond water at a distance [x]-m from the bottom edge of the dock. Find the speed she runs off the dock.

Vector A has magnitude [A], and vector B has magnitude [B].  The angle between them is [AngleDeg] degrees. What is the magnitude of product A x B ?

Given two vectors A =  -3 i + 4 j   and B = 4 i – 3 j  . Let  C = A x B . Which direction does C point to?

You throw a ball vertically upward from the roof of a building.  The ball leaves your hand at even with the roof railing with an upward speed of [v0] m/s; the ball is then in free fall. On the way back down, it just misses the railing and hits the ground [t] s after it leavs your hand.  How tall is the building?

A boy throws a rock with an initial velocity of [v] m/s at [angle] degrees above the horizontal.  If air resistance is negligible, how long does it take for the rock to reach the maximum height of its trajectory?

Questions 20-22 refer to the following case: Responses to 2 different types of parasympathomimetic drugs are to be compared. Drug X is a direct-acting parasympathomimetic and drug Y is an indirect-acting parasympathomimetic drug.  Drug X would:
