. A psychologist who has never administered Test X is asked to evaluate a child who the psychologist feels should be administered this test. However, a psychology graduate student who is supervised by the psychologist has previously been supervised in administering, scoring, and interpreting Test X. The student should not administer this test under the psychologist's supervision because: A. the psychologist would not be able to supervise the student's work. B. the psychologist would not be able to understand the results of the test. C. the psychologist would not be able to evaluate the psychometrics of the test D. the psychologist should assign work to the student based on the student's learning needs and not on the psychologist's needs.

0/2 points Previous Answers SerPSE10 24.2.OP.006. My Notes Ask Your Teacher A small object is connected to a lightweight cord of length $l = 1.20 \text{ m}$ that is tied to a point $P$, as shown in the figure. $p$ $v = 0$ $q$ $L$ $\theta$ Top view The object, string, and point all lie on a frictionless, horizontal table. The object has a mass $m = 0.0100 \text{ kg}$, a charge $q = +1.50 \mu \text{C}$ and is released from rest when the string makes an angle $\theta = 60.0^\circ$ with a uniform electric field of magnitude $E = 250 \text{ V/m}$. Determine the speed (in m/s) of the object when the string is parallel to the electric field. 4.5 Since the table is frictionless, and the object-field system is isolated, we may conserve energy. As a matter of convenience, set $V = 0$ at point $P$. Determine expressions for the electric potential energy and kinetic energy at the initial and final positions and conserve energy. m/s
