Unformatted text preview: pavlyukovskyy (mp24573) Physics 1710 Homework 1 Weathers (17104) 1 This printout should have 9 questions. Multiplechoice questions may continue on the next column or page find all choices before answering. 001 10.0 points The mass of the planet Saturn is 5 . 64 10 26 kg and its radius is 6 10 7 m. Calculate its density. Answer in units of kg / m 3 . 002 10.0 points This problem shows how dimensional analysis helps us check and sometimes even find a formula. A rope has a cross section A = 10 . 3 m 2 and density = 2010 kg / m 3 . The linear density of the rope , defined to be the mass per unit length, can be written in the form = x A y . Based on dimensional analysis, determine the powers x and y by choosing an expression below. 1. = A 2 2. = A 3. = A 4. = A 2 5. = A 2 6. = 1 A 7. = A 8. = 1 A 2 9. = A 2 10. = A 2 2 003 10.0 points A light year is the unit of distance that light, with a speed of 2...
