•We have three small fixed spheres A, B and C electrically charged. Sphere A has a positive charge and attracts
sphere B. Sphere B attracts sphere C.
a. What kind of charge does sphere B have and what is the sphere C.
b. Are spheres A and C attracted or repelled by each other?

depends on what you mean by "group." for order, it would be coleoptera (beetles). for class, it would be insecta (insects). for phylum, it would be the arthropoda (animals with jointed exoskeletons).

explanation:

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

explanation:

-reverse card

total distance/total time

(85 + 82)/(5+3)

167/8

20 just over

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
