The block in the drawing has dimensions l0×2l0×3l0,where l0 =0.5 m. the block has a thermal conductivity of 200 j/(s·m·c˚). in drawings a, b, and c, heat is conducted through the block in three different directions; in each case the temperature of the warmer surface is 37 ˚c and that of the cooler surface is 7 ˚c determine the heat that flows in 4 s for each case.

Explanation:

Given:

REFER THE ATTACHED IMAGE FOR THE REFERENCE

The rate of heat flow using Fourier's law of conduction is given as:

Now the amount heat flow perpendicular to the pink surface:

Now the amount heat flow perpendicular to the orange surface:

Now the amount heat flow perpendicular to the green surface:

acceleration = (change in speed) / (time for the change)

change in speed = (20-120)= -100 m/s.

1.5 min = 90 sec

acceleration = -100/90 = -1.11 m/s^2.

we don't care about the 150kg or the 2,500 meters. they don't make any difference.
