Unformatted text preview: Physics 207 Homework 1 Solutions Due 9/14/05
Assignment: Ch 1, problems 6, 10, 14, 17, 23, 30, 38, 43, 48, 50 Prob 1.6) The volume of an individual sphere is given by: 4 V r3 3 If we substitute equation 1 into 2 we find that: 4 m r3 (6.3) 3 Now, dividing equation 6.3 for the large sphere by equation 3 for the small sphere and using that the ratio of large mass to small mass is five gives the following: 4 r3 large mlarge r3 3 large 5 (6.5) 3 m small 4 r small 3 r small 3 Multiplying by the cube of the small radius and taking the cube root gives us the answer: r large 3 r small (6.6) Prob 1.10) (a) The volume of a cube is given by the cube of the length so the mass is given by the density times the length cubed: m V L 3 7.8...
