The table shows the potential energy and kinetic energy of a skier at two different positions on a hill. position and energy position (above ground) kinetic energy potential energy 100 meters 0 units 50,000 units 60 meters ? 30,000 units what is the kinetic energy of the skier at a height of 60 meters above ground? 20,000 units, because total energy remains unchanged 80,000 units, because total energy remains unchanged 20,000 units, because total energy of the skier decreases 80,000 units, because total energy of the skier decreases

Sally, age 3 months, has a moist, red, vesicular rash on her cheeks, the backs of her hands, and her arms. her mother said sally was constantly trying to scratch the rash and often has difficulty sleeping. her father has a family history of allergic rhinitis and asthma. discussion questions. 1. review atrophic dermatitis from chapter 3 and discuss the pathophysiology of sally’s symptoms. 2. why is the father’s medical history significant, and what can sally expect as she grows up? 3. discuss the need to limit scratching, and describe practical methods to achieve this.
