9. [0/4 Points] The figure below is an aerial view of the surface of the ocean. A ship is at point B on the surface, a submarine is 7 units below the surface at point C, and a helicopter is 9 units above the surface at point 2 3 (a) Find the displacement vectors for the following: From the submarine to the ship. -2i + 3j - 9k X From the helicopter to the ship. From the submarine to the helicopter. (b) Which two objects are closest together? (Select the two that apply.) Note: The interpretation of "closest" here refers to how the objects look with respect to the surface of the ocean (or in 2-D.) O submarine O ship O helicopter
