Answer:
t = 2244.3 sec
Explanation:
calculate the thermal diffusivity
Temperature at 28 mm distance after t time = = 50 degree C
we know that
![\frac{ 50 -25}{300-25} = erf [\frac{28\times 10^{-3}}{2\sqrt{1.34\times 10^{-5}\times t}}]](https://tex.z-dn.net/?f=%5Cfrac%7B%2050%20-25%7D%7B300-25%7D%20%3D%20erf%20%5B%5Cfrac%7B28%5Ctimes%2010%5E%7B-3%7D%7D%7B2%5Csqrt%7B1.34%5Ctimes%2010%5E%7B-5%7D%5Ctimes%20t%7D%7D%5D)
from gaussian error function table , similarity variable w calculated as
erf w = 0.909
it is lie between erf w = 0.9008 and erf w = 0.11246 so by interpolation we have
w = 0.08073
![erf 0.08073 = erf[\frac{3.8245}{\sqrt{t}}]](https://tex.z-dn.net/?f=erf%200.08073%20%3D%20erf%5B%5Cfrac%7B3.8245%7D%7B%5Csqrt%7Bt%7D%7D%5D)
solving fot t we get
t = 2244.3 sec

Answer: C. Problem identification, solution design, implementation, evaluation.
Explanation:
If ceramic vessels are typed together based as they were all used as storage containers, in spite of the fact that design elements indicate they are from different time periods, then they have to be functional typeoperational typesystematic type is given below
Explanation:
The Batiscan site, excavated in the 1960s, produced one of the largest Vinette I collections known to date. Revisiting this ceramic assemblage has revealed more heterogeneity than is generally recognized within the Vinette I type of pottery. Indeed, variations from the typological definition exist, both within and between Early Woodland ceramic collections. A number of diagnostic traits, such as the presence of exterior and interior cord impressions and the absence of decoration, are challenged by the present study. It is hypothesized that part of this variability is chronological, and that the vessels from Batiscan were manufactured closer to the end of the Early Woodland period. However, other factors, such as the frequency and scale of production, and the possible exchange and circulation of ceramic containers, must also be taken into account when interpreting Vinette I variability.l
