What was the effect of climate change on the Harappan culture of ancient Pakistan?
What do measurements of cardon dioxide (CO2) done on Mauna Loa indicate is happening to the level of CO2 in the atmosphere?
What is the expected impact on the climate of the planet Earth due to the above CO2 observations?
What is thought to be the source of the CO2?
A RipStik was swizzled ("wiggled") across a poster paper. The sinusoidal swizzle wave can be seen in the diagram below along with the measurements.
_________ How many wavelengths are shown?
λ = _________ _________ Calculate the wavelength λ of one wave in centimeters.
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.
A clapper clapping in synch with the echo claps 25 times in ten seconds during laboratory nine. The distance to the building and back was 132 meters.
τ = ________ _________ Based on this data, what is the period for the echo (the out-and-back time in seconds for one echo)?
velocity ѵ = _________ _________ Based on this data, what is the speed of sound?
percent error = _________ Given that the actual speed of sound that day was 350 m/s, what is the percentage error?
_______________ ______________ What precipitation process generates most of the daily rain on Pohnpei?
_______________ ______________ What precipitation process generates rain when air is lifted up by terrain?
_______________ ______________ What precipitation process generates rain in a thunder and lightning storm cell?
For the next few questions the instructor should have brought a thermometer.
He will write some values on the board. Use those values for the questions below.
_______°C What is the dry bulb temperature?
_______°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?
distance d = velocity ѵ * time t
period τ = 1 ÷ (frequency f )
velocity ѵ = wavelength λ * frequency f
Relative humidity from dry bulb and wet bulb depression
Web bulb depression in °C: Dry bulb minus the wet bulb
