宫腔内探及一囊性暗区,大小约0.7*0.6*0.5cm,周边回声增强,其内未见胎块，确定是怀孕吗？谢谢_百度宝宝知道孕42天阴道少量出血超声所见右侧附件区有5.3*5.2cm囊肿孕58天查6.7*6.4cm我想保住胎儿，请问我该怎么办？_百度宝宝知道Problem 17A

Section 17-1 Review, page 633
1) It is equal to the magnitude of the rod' Charge is conserved. 2) Charge is quantized. 3) 6.25 x 10^19 electrons 4) The taped induces a surface charge on the desk, so the two are attracted to one another. 6) More paint hits the object being painted because of an electrical attraction between the chargted droplets and the oppositely charged object.
Section 17-2 Review, page 642
1a) 4.4 N b) attractive c) 1.2 x 10^13 electrons 2) both are field forces, both are electric forces are attractive or repulssive whnile gravitational forces are always attractive, electric force is significantly stronger than gravitational force 3) 7.3 x 10^-8 N, along the negative x axis 4) 35.2 cm from q(1) (24.8 cm from q(2)) 5) new distance = 1/sqrt(2)(old distance)
Section 17-3 Review, page 652
1) 8.0 x 10^3 N/C, directed toward the 40.0 x 10^-9 C charge 2a) -3/8 b) q(1) q(2) is positive 3a) All lines should point away from the two charges, and one charge should have four time as many lines as the other. b) All lines should point toward the tow charges, and one charge should have four times as many lines as the other. 4) because charge accumulated at sharp points 5) They experience an electrical attraction that pulls them back toward the object.
Section 17-1 Worksheet
1a) Experiment A, no charges were transferred. Experiment B, charges were tranferred between the sphere and the ground. Experiment C, Charges were transferred between the sphere and the rod. b) Diagrams should show: Spher A, negative charges (-) on the left, positive (+) Sphere B, excess (-) Sphere C, excess (+) d) Experiment A e) no change in Experiment A or Experiment B; reduced charge in Experiment C
