In a two-page paper, identify the physics principles contained within the following scenario. explain how these principals connect to einstein's theory of relativity or in modern applications in physics. if you use a gps option on your car or a mobile device, you are using einstein's theory of relativity. finally, provide another example from your own experience, then compare and contrast your scenario to the provided example below.
scenario:
mandy took a trip to rome, italy. she gazed out over the open ocean 20,000 feet below as her airplane began its descent to her final destination of rome. it had been a long flight from new york to rome, but she as she stretched, and her bones creaked as though she was old, she knew that in fact, she was a tiny bit younger than her compatriots back home, to traveling at hundreds of miles per hour. in fact, time for her was running slowly compared to her friends in new york for two reasons: the speed at which she had traveled and the height of the airplane above the earth. neither, though, were noticeable.

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?
