In an experiment, students connect resistors R1R1 and R2R2 to battery VV. The students hypothesize that as heat is dissipated in the resistors, the temperature of the resistors increase at a constant rate. Which curve represents the expected current through the resistors as a function of time if this hypothesis is correct

the answer is a. at the equator

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. 

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
