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.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
