A mobile is constructed of light rods, light strings, and beach souvenirs as shown in the figure below. If m4 = 12.0 g, find values for the following. (Let d1 = 3.60 cm, d2 = 5.10 cm, d3 = 1.80 cm, d4 = 5.20 cm, d5 = 3.70 cm, and d6 = 4.60 cm.)
(a) m1

(b) m2

(c) m3 =
m1 = ?
m2 = ?
m3 = ?
m4 = 12 g
For the lowest rod,
Distance of m1 from the support string of the lowest rod = d6 = 4.6 cm
Distance of m4 from the support string of the lowest rod = d5 = 3.7 cm
Balancing the moment of the lowest rod about the point where the support string is attached,
m1d6 = m4d5
m1(4.6) = (12)(3.7)
m1 = 9.65 g
For the middle rod,
Distance of m2 from the support string of the middle rod = d3 = 1.8 cm
Distance of the string supporting the lowest rod from the support string of the middle rod = d4 = 5.2 cm
Balancing the moment of the middle rod about the point where the support string is attached,
m2d3 = (m1 + m4)d4
m2(1.8) = (9.65 + 12)(5.2)
m2 = 62.54 g
For the topmost rod,
Distance of m3 from the support string of the topmost rod = d2 = 5.1 cm
Distance of the string supporting the middle rod from the support string of the topmost rod = d1 = 3.6 cm
Balancing the moment of the topmost rod about the point where the support string is attached,
m3d2 = (m1 + m2 + m4)d1
m3(5.1) = (9.65 + 62.54 + 12)(3.6)
m3 = 59.43 g
a) m1 = 9.65 g
b) m2 = 62.54 g
c) m3 = 59.43 g

1) We use this formula: [Experimental value – Theoretical value]/ [Theoretical value] to calculate: Group of answer choices Atomic decay Biased Error Relative percent error Efficiency Redshift 2)You measure the diameter of a cylinder 5 times and get five different values (d1, d2, d3, d4, d5.) Then, the average value would be: Group of answer choices (d1 x d2 x d3 x d4 x d5) divided by 5 (d1 + d2 + d3 + d4 + d5) divided by 5...
