Aperson's body is covered with 1.69 m^2 of wool clothing. the thickness of the wool is 1.87 × 10^-3 m. the temperature at the outside surface of the wool is 13.9 °c, and the skin temperature is 35.4 °c. how much heat per second does the person lose due to conduction?

The concept required to solve this problem is related to heat conductivity as a function of time.

Mathematically in a stable state the heat flux is constant and its rate of change as a function of time can be described under the function

Where

k= Coefficient of thermal conductivity

A = Area of the object

=Temperature difference across object

d= thickness of object

According to the values given we have then,

Replacing we have,

Therefore the quantity of heat per second does the person lose due to conduction is 777.21J/s

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
