The soil temperature in the upper layers of the earth varies with the variations in the atmospheric conditions. before a cold front moves in, the earth at a location is initially at a uniform temperature of 10°c. then the area is subjected to a temperature of -10°c and high winds that resulted in a convection heat transfer coefficient of 40 on the earth’s surface for a period of 10 h. taking the properties of the soil at that location to be k = 0.9 and alpha = 1.6 x 10^5, determine the soil temperature at distances 0, 10, 20, and 50 cm from the earth’s surface at the end of this 10 h period.

Describe different biomes. what are some adaptations that organisms (plants or animals) must have to live in each biome?

5submission this assignment is worth 20 points total. you are required to submit the following by next lab: 1. (3 points) determine the equation for the output angular velocity ω2 = θ˙ 2 as a function of θ1, ω1 = θ˙ 1 and α. you must show all your work to receive credit. 2. (2 points) use the result of problem#1 to plot ω2 over 0 ≤ θ1 ≤ 360deg with ω1 = 360deg/sec. do this for α = {10,30}deg. show the results on the same plot and properly label the axes, title, legend. for this you can use matlab or ms excel. 3. (3 points) determine the equation for the output angular acceleration ω˙ 2 and create a plot similar to the one in problem#2. 4. (10 points) submit plots of the results (ω2 and ω˙ 2) obtained from creo/mechanism and compare them to results of problem#2 and problem#3. note that you should do these comparisons for the two cases with α = {10,30}deg. 5. (2 points) provide a brief explanation of the results. did they match? what are the implications as misalignment angle increases?
