ASTR 1102 : Exam 1 Hw
Document Summary
1102 hw #1: the distance from the sun to mars is about 220,000,000 km. Count the number of digits (both zero and nonzero) that are to the right of the rst digit (but to the left of the decimal point, if there is one present); there are eight digits in 20,000,000. This number, eight, is then the exponent of 10. Reality is comprehensible, and a limited number of fundamental principles govern the nature and behavior of the universe. This sentiment is the basis for scienti c study, and it is borne out by observation. Groupings of stars that cover various areas of sky from large to small: a perfect blackbody. Very long wavelength radio, long wavelength microwave, intermediate wavelength . How would the blacksmith have to change its temperature in order that this peak wavelength would move to 0. 5. Double its temperature: in a vacuum, blue light differs from red light in that.
