Directions and Analysis Task 1: Modeling the Solar System In this task, you will design a scale model of the solar system. A simple scale model would depict the Sun and eight planets to scale. Research online for resources that provide information on creating a model that scales up to the proper dimensions of the solar system. Use this site to calculate a scale for the various bodies in the solar system by specifying a fixed size for the Sun. (Note: distances between planets in the solar system are extremely large, so it is recommended to perform this task in an open park for best results.) Record your findings and provide a detailed explaination of how you visualized your scale model. Type your response here:

Clothing made of several thin layers of fabric with trapped air in between, often called ski clothing, is commonly used in cold climates because it is light, fashionable, and a very effective thermal insulator. so it is no surprise that such clothing has largely replaced thickand heavy old-fashioned coats. (a) consider a jacket made of five layers of 0.1-mm-thick synthetic fabric (k = 0.13 w/m·°c) with 1.5-mm-thick air space (k = 0.026 w/m·°c) between the layers. assuming the inner surface temperature of the jacket to be 28°c and the surface area to be 1.25 m2, determine the rate of heat loss through the jacket when the temperature of the outdoors is 0°c and the heat transfer coefficient at the outer surface is 25 w/m2·°c. (b) what would your response be if the jacket is made of a single layer of 0.5-mm-thick synthetic fabric? what should be the thickness of a wool fabric (k = 0.035 w/m·°c) if the person is to achieve the same level of thermal comfort wearing a thick wool coat instead of a five-layer ski jacket?
