An ideal Carnot engine operates between 500C and 100C with a heat input of 250 J per cycle. (a) How much heat is delivered to the cold reservoir in each cycle? (b) What minimum number of cycles is necessary for the engine to lift a 500-kg rock through a height of 100 m?
BSCI 201: Anatomy & Physiology Chapter 6 (The Skeletal System) - Part 1 Notes by Mehrnaz Ighani . The human skeleton initially consists of just cartilage, which is replaced by bone, except in areas requiring flexibility . Skeletal cartilage: made up of highly resilient, molded cartilage tissue that consists primarily of water Contains no blood vessels or nerves . Perichondrium: layer of dense CT surrounding cartilage Contains blood vessels for nutrient delivery to cartilage Helps cartilage resist outward tension . Cartilage is made up of chondrocytes, cells encased in small cavities (lacunae) within jelly like ECM . 3 types of cartilage: (Fig. 6.1) 1. Hyaline: . provides support, flexibility, and resilience . most abundant, contains collagen fiber
