A vector has an x-component of length 3.5 and a ycomponent of length 3. What is the angle of the vector? (Hint: Use the inverse tangent.)

newton's first law of motion

.) the observation by semmelweis that more mothers died of childbed fever when their doctors also worked in the morgue

the working equation for the angular size is the product of the physical size and 360 degrees divided by the product of two pi and distance from earth. the minimum size would be 0.559 degrees while the maximum size would be 0.49 degrees. 

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
