3. In your physics log, create a data table. Record each station's name and the
measured direction (with reference to north) and speed.
a) Are all stations on the map moving at the same speed? What patterns do you observe
from one part of the United States to another? Use data to support your explanation.
b) Are all stations on the map moving in the same direction? What patterns do you
observe from one part of the United States to another? Use data to support your
explanation.

Determine the maximum r-value of the polar equation r =3+3 cos 0

Researchers determine that the biodiversity in a woodland region is declining. they identify two major threats to the region's biodiversity, a method to address each threat, and the expected outcome of each method. this information is shown in the table. a) reforestation would not benefit many species because most forest species live on the ground. b) reforestation would take the longest time to be effective because trees take several years to grow. c) biological augmentation would benefit only a few species because is is typically not very effective. d) biological augmentation would take less time to ve effective because it targets the majority of prey species.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.
