Capacitance of a Thundercloud. The charge center of a thundercloud, drifting 3.0 km above the earths surface, contains 20 C of negative charge. Assuming the charge center has a radius of 1.0 km, and modeling the charge center and the earths surface as parallel plates, calculate: (a) the capacitance of the system; (b) the potential difference between charge center and ground; (c) the average strength of the electric field between cloud and ground; (d) the electrical energy stored in the system.
Lecture Objectives 10 1. Describe the anatomy different kinds of joints and the type of movement allowed Functional categories Synarthroses - immovable Amphiarthroses - slightly moveable Diarthroses - freely movable Structural Categories Fibrous - bones linked by collagen fiber of connective tissue - little to no movement - Synarthroses and Amphiarthroses Cartilaginous - bones linked by cartilage connective tissue - little to no movement - S ynarthroses and Amphiarthroses Synchondroses - bones united with hyaline cartilage Symphyses - bones united by fibrocartilage Synovial - ends of bones not connected by connective tissue; separated by fluid filled joint cavity - movement iarthroses
