WX 201 FINAL EXAM REVIEW QUESTIONS WITH CORRECT ANSWERS What does NOT contribute to making Salt Lake City colder than Seattle during winter? - Answer-Seattle has more cloud cover than Salt lake City, which traps outgoing infrared radiation and keeps temperatures from getting as cold. What is the solar elevation angle over Sao Paulo, Brazil (lat. 24 s) at noon on Dec. 22? - Answer-89.5 Earth has seasons - Answer-Because of Earth's tilt angle Daily high temperatures usually occur - Ans...

The range of wavelengths in the visible spectrum is? correct answers 400 - 800 nanometers Immediately on either side of the visible spectrum are the invisible light segments of? correct answers Infrared & ultraviolet Which color has the longest wavelength? correct answers Red Geometric optics includes? correct answers The effects of media on the path of light When light bounces back from an object, this is known as? correct answers Reflection In reflection, the light rays that hit...

ARDMS SPI STUDY GUIDE QUESTIONS AND ANSWERS ALREADY PASSED In soft tissue, if the frequency of a wave is increased the Propagation Speed (PS) will... Remain the Same because stiffness and density affect Propagation Speed. What is the audible range? 20-20,000Hz >20,000Hz=Ultrasound Frequency is measured in Hertz (Hz) is Cycles per Second Not affected by sonographer Increase Frequency; Decrease Depth A period is the length of time it takes for one complete wavelength to pass a fixed poin...

What is the Gulf Stream? - Answer What is the thermocline? - Answer The area where there is a rapid temperature decrease with a depth of a few hundred meters below the surface How does oceanic temperature vary with depth? - Answer Warmest temperature found near surface (absorbs solar radiation) Then thermocline (temperature decreases rapidly) Deep ocean waters are only a few degrees above freezing What is upwelling? How does it affect oceanic temperature? - Answer Vertical transport ...

Define Wien's Law - The hotter an object, the shorter the wavelength at maximum emission. (The hotter the object the brighter) After a cold front passes what happens to dew point? - it drops, as cold air is typically dry Centripetal force wind - right angles to the wind, in towards the center of curvature ex. hurricanes Convection is the process that? - involves mixing in a fluid Coriolis effect - The effect of Earth's rotation on the direction of winds and currents. Define a category fi...

Navigation fixes whose holding defined holding-pattern airspace doesn't overlap o Easy if airways are parallel to each other and are 8 miles apart o If not ll, then course divergence is needed (navigation off same NAVAID, distance from NAVAID re...

ARRT Registry Practice Test1 All of the following EXCEPT ___ will result in an increase in AEC response time. a. decreasing the kVp b. Increasing the focal spot size c. increasing the part thickness d. increasing the SID - ANSWER b. increasing the focal spot size Increasing the focal spot size does not change the AEC response time It affects the spatial resolution. Decreasing the kVp increases the exposure time because more photons are absorbed, resulting in fewer...
