  2. ______________ If you are at E 158° 09.657' and walk to E 158° 09.474', which direction did you walk: north, south, east, or west?
  3. _________ _________ Faunaleen walked from E 158° 09.657' to E 158° 09.474'. How far did Faunaleen walk in minutes?
  4. _________ _________ While walking from E 158° 09.657' to E 158° 09.474' Joyceleen measured a distance of 348 meters. Calculate the number of meters per minute.
  5. For the next few questions the instructor should have brought a thermometer and tables of values. He will write some values on the board. Use those values for the questions below.

    _______°C What is the dry bulb temperature?
  6. _______°C What is the wet bulb temperature?
  7. _______% Use a table to determine the relative humidity.
  8. _______°C Use a table to determine the heat index (the perceived temperature).
  9. ______________ What is the risk level for exercise: low, moderate, or high?
  10. ______________ Is Micronesia presently experiencing an El Niño or a La Niña?
  11. ______________ In which condition are Pohnpei and Kosrae most likely to experience tropical storms and typhoons: El Niño or a La Niña?
  12. ______________ In which condition are Pohnpei and Kosrae most likely to experience droughts (no rain) in the months of January, February, and March: El Niño or a La Niña?
  13. ______________ During an El Niño, towards which direction does the western Pacific warm pool water flow?
  14. Explain the meaning of neap tide, spring tide, and king tide.
  15. A RipStik was swizzled ("wiggled") across a poster pad paper. The sinusoidal swizzle wave can be seen in the diagram below.
    RipStik swizzle sine wave 8 cm 30 cm RipStik rider

    λ = _________ _________ Determine the wavelength λ of one wave of the RipStik swizzle wave.
  16. a = _________ _________ Determine the amplitude a of the RipStik swizzle wave.
  17. τ = _________ _________ The RipStik took a duration of 0.30 seconds to travel the 30 centimeters seen on the diagram above. Determine the period τ for the RipStik swizzle wave.
  18. f = _________ _________ Calculate the RipStik swizzle wave frequency f.
  19. ѵwave = _________ _________ Use the wavelength λ and frequency f to calculate the velocity ѵwave of the RipStik swizzle wave.
  20. _________ How many wavelengths in all are there on the "paper" above?
  21. Bouncing ball ball arrows τ = _________ _________ A ball bounces 10 times in 4 seconds. What is the period of the bouncing ball?
  22. f = _________ _________ A ball bounces 10 times in 4 seconds. What is the frequency for the bouncing ball?
  23. τ = ________ _________ While gathering data for laboratory nine, a clapper clapping in synch with the echo claps 20 times in ten seconds. Based on this data, what is the period for the echo (the out-and-back time)?
  24. velocity ѵ = _________ _________ During ten seconds a clapper claps 20 times. The echo flight distance is measured as being 175 meters. Based on this data, what is the speed of sound?

distance d = velocity ѵ * time t
period τ = 1 ÷ (frequency f )
velocity ѵ = wavelength λ * frequency f
