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.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !

h o h o hope you have a merry christmas!

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg
