Find the angle between each pair of vectors below. (1 point each) a. a = 2x + 3y a = 4x + 2y b. a = x + y a = x – y c. a = 2x – 3y a = 5x + y d. a = x – 6y b = 2x – 2y question 7 (2 points) two cars are driving down separate streets in the same city. the velocity of car a is given by the vector a = (2x + 3y) m/s. the velocity of car b is given by the vector b = (5x + 2y) m/s. what is the angle between the paths of the two cars? (2 points) question 8 (2 points) for three-dimensional vectors, the dot product is given by this equation: a·b = axbx + ayby + azbz a. based on this definition, what is the dot product of the vectors shown below? (1 point) a = 2x + 2y – z b = –3x – y + 3z b. what is the angle between the two vectors above? (1 point) question 9 (2 points) the velocity vectors of two airplanes are given below. a = (250x + 350y – 50z) m/s b = (100x – 500y + 50z) m/s what is the angle between the paths of the two airplanes? (2 points)

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?
