_______°C What is the wet bulb temperature?
_______% Use a table to determine the relative humidity.
_______°C Use a table to determine the heat index (the perceived temperature).
______________ What is the risk level for exercise: low, moderate, or high?
As a runner who juggles (joggler), I have to be constantly of the wind environment around me.
In the diagram a joggler in the wind shadow (the leeward side) of a building approaches the corner of the building.
The air speed is higher at the corner of the building. What is the name of this effect?
A RipStik was swizzled ("wiggled") across 160 centimeters of poster paper in a time of two seconds. The sinusoidal swizzle wave can be seen in the diagram below.
λ = _________ _________ Calculate the wavelength λ of one wave.
a = _________ _________ Calculate the amplitude a.
τ = _________ _________ Calculate the period τ.
f = _________ _________ Calculate the RipStik swizzle wave frequency f.
ѵwave = _________ _________ Use the wavelength λ and frequency f to calculate the velocity ѵwave of the RipStik swizzle wave.
ѵboard = _________ _________ Use the 160 centimeters traveled and the two seconds to travel that distance to calculate the velocity ѵboard of the RipStik board.
_________ Is ѵwave equal to ѵboard?
_________ How many wavelengths in all are there on the "paper" above?
A ball bounces 40 times in 10 seconds.
τ = _________ _________What is the period of the bouncing ball?
f = _________ _________ What is the frequency for the bouncing ball?
During laboratory nine, the speed of sound, a student is 136 meters from the female residence hall banging two boards together in synch with the echoes. The other students count 25 claps in ten seconds.
τ = ________ _________ What is the period for the echo (the out-and-back time)?
velocity ѵ = _________ _________ What is the experimental speed of sound?
% error = _________ _________ Given that the actual speed of sound that day was 347 m/s, what is the percentage error?
Plot the data provided on the graph below and draw a line through the points. Use the data and chart to calculate the speed of sound.
Speed of sound: _____________ _________

color.
List the seven colors of the Newtonian spectrum in order:
distance d = velocity ѵ * time t
