1.97moles
106.7/(1.01x2+16)/3x1 = 1.97
Answer:
What are the choices? I would say if "Southern Hemisphere is winter" pick that one
Explanation:
Opposite sides of Earth
Explanation:
The given data for case (1) is as follows.
h = 20 cm = 0.2 m
Assuming that a rectangular slab is placed above the pipe and we will calculate the heat transfer as follows.
Q =
where, A = area
L = length
k = thermal conductivity = 0.8 W/m
= change in temperature.
Therefore, putting the given values into the above formula as follows.
Q =
=
= 168 W
For case (2), h = 180 cm = 1.8 m
Therefore, heat lost will be calculated as follows.
Q =
=
= 18.67 W
Thus, we can conclude that 18.67 W heat lost if the pipe was buried at a depth of 180 cm.
Thomson’s plum pudding model of the atom was later found to be inadequate following the discovery of the nucleus by Rutherford.
