The chart plots the level of carbon dioxide in the atmosphere.
According to An Inconvenient Truth, what is causing the carbon dioxide levels to rise?
What is the cause of the annual rise and fall, the annual cycle, in the carbon dioxide levels?
What will be the effects on the planet of the rise in atmospheric carbon dioxide?
In Al Gore's July article in the Rolling Stone, The Turning Point: New Hope for the Climate , Al Gore notes that Last April, the average carbon dioxide concentrations in the Earth's atmosphere exceeded a particular value on a sustained basis for the first time in at least 800,000 years and probably for the first time in at least 4.5 million years (a period that was considerably warmer than at present). What remarkable value for carbon dioxide was exceeded in April 2014?
What is reflection?
What is refraction?
Plot the following data on the graph provided and draw a linear best fit line through the data points on the graph.
______________ Calculate the slope of the linear best fit line. The slope is the experimental index of refraction for the material.
______________ __________ Use the equation of the best fit line above to predict the image depth for a coral head that is 200 cm underwater.
______________ The above material is reported to have a theoretic index of refraction of 1.5. What is the percentage error for the slope you calculated based against a theoretic value of 1.5?
__________ _____ For a Brother XR-7700 sewing machine, calculate the power used based on the information in the images.
__________ _____ For a Brother XR-7700 sewing machine, calculate the resistance.
___________ __________ What type of circuit produces "no light and no heat"?
___________ __________ What type of circuit produces "light but no heat"?
___________ __________ What type of circuit produces "heat but no light" (the wires become hot)?
Plot the data below on the graph provided. Draw a best fit trend line through the data.
____________ ________ For the data above, what is the resistance?
List three forms of alternate energy generation
__________ What is the atomic number of Zn?
__________ What is the atomic mass of Zn?
__________ How many protons does Zn have?
__________ How many neutrons does Zn have?
__________ How many electrons does Zn have?
____________________ Zn was an element tested in the electrical conductivity, what is the full name for Zn?
Remember that the number of neutrons equals or exceeds the number of protons. The number of protons cannot exceed the number of neutrons in a stable element. Thus the more numerous nucleons are the neutrons.
