In arrests without a warrant, the ________________ makes the initial determination of probable cause.

A thin oil film (n = 1.48) floats on water. When green light of wavelength 545 nm enters the oil from air, it produces a strong reflection.  How many phase changes are present? [phasechanges] Do we have constructive or destructive interference in this scenario? [interference] Show your work or explain your reasoning. 

A diffraction grating with 670 slits/mm is illuminated by a light. The second-order angle is measured at 39° from the center. What is the wavelength of this light in nanometers?

Reasonable suspicion is the requirement for obtaining a warrant.

An object is placed in front of a mirror. The observer is positioned as shown. Which point best indicates where the observer would perceive the image to be located? You do NOT need to explain your reasoning for this question.   

Fill in the blanks. You do NOT need to explain your reasoning for this question. Although both a human eye and a camera have a [lens] lens, they operate differently in order to form focused images. In a camera, the lens is moved toward or away from the object in order to focus. In a human eye, the ciliary muscles in the eye change the shape of the lens effectively changing the [shape] of the lens itself. 

The more circumstances taken into account means the less likelihood of establishing probable cause or reasonable suspicion.

Refer back to the previous question, where you found the electric potential at point A in the figure. Say that a charged particle were placed at point A and you determined that the electric potential energy it experiences is -5.0 x 10-6 J. What is the charge (in nC) on the particle at point A? Show all of your work. 

Let’s say you wanted the circuit above to discharge slower once the switch is closed. Which of the following would cause the current in the RC circuit to decline slower? Select all that apply for full credit. You do NOT need to show your work or provide an explanation for this question.

  A positive charge moves as shown. Its kinetic energy will __________ as it travels toward the positive plate. You do NOT need to show your work or explain your reasoning in this problem.
