Consider the possible scenarios and determine which of them are true for positive feedbacks or negative feedbacks. select the three that apply view available hint(s)
hint 1. negative vs. positive feedback
hint 2. material color and solar reflectivity select the three that apply
a. increased evaporation resulting from a temperature rise can produce more clouds which can potentially lead to a positive feedback
b. if ice cover melts due to a temperature rise the result will be decreased albedo or reflectivity which can potentially
lead to a positive feedback
c. increased plant photosynthesis resulting from a temperature rise can remove carbon dioxide from the atmosphere which can potentially lead to a positive feedback
d. if ice cover melts due to a temperature rise the result will be decreased albedo or reflectivity which can potentially lead to a negative feedback
e. increased plant photosynthesis resulting from a temperature rise can remove carbon dioxide from the atmosphere which can potentially lead to a negative feedback
f. increased evaporation resulting from a temperature rise can produce more clouds which can potentially lead to a negative feedback

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
