Problem 44

For the human body, what is the rate of heat transfer by conduction through the bodys tissue with the following conditions: the tissue thickness is 3.00 cm, the change in temperature is 2.00C , and the skin area is 1.50 m2 . How does this compare with the average heat transfer rate to the body resulting from an energy intake of about 2400 kcal per day? (No exercise is included.)

Step-by-Step Solution:
Step 1 of 3

Physics 1500 – Dr. Hebert Week of August 21, 2016 Free Fall Motion  If I hold an apple at some height and let it go, what happens  If I throw an apple straight up, what happens  Freely falling objects – objects moving under only the influence of gravity o Take the acceleration du2 to gravity as a constant  a = g = 9.8 m/s o can use the kinematic equations to describe motion  the acceleration due to gravity always points toward the surface of the Earth  3 cases of free fall motion – dropping the ball, throwing the ball up, throwing the ball down    exa mpl e problem  Kinematic equations do NOT depend at all on mass of the object  This means, neglecting air resistance, two objects should fall at the same rate regardless of their respective masses o Apollo 15 tested this on the moon Vectors  Acceleration, velocity, and displacement are all vectors  In one dimension, dealing with vectors is easy: one way is positive, and the other is negative  Two dimensions is more difficult  Two vectors are equal if they have the same direction and the same magnitude  Vectors don’t care where they are, just magnitude
