Answer:
Q=7200 W
q=7200/72=100
Explanation:
Given that
ΔT=15° C
Thickness ,t=15 cm
Thermal conductivity ,K=1 W/m.°C
Height,h=6 m
Length ,L=12 m
As we know that heat conduction through wall given as
Now by putting the values
A= 6 x 12 =72
Q=7200 W
Q is the total heat transfer.
Heat flux q
q=Q/A
q=7200/72=100
q is the heat flux.
As w know that heat flux(q) is the heat transfer rate from per unit area and on the other hand heat transfer(Q) is the total heat transfer from the surface.
Heat flux q=Q/A
That is why these both are different.
Answer:
False
Explanation:
Valence electrons depend of their what group they're in.
Before I get to the answer, I would recommend that you post biology questions under the biology category. You should get your answers more quickly that way :)
There are two things that happen before a parent cell divides:
1) DNA in the nucleus of the parent cell must replicate (this happens in the S phase of the cell cycle). If you're looking for a single answer to your question, then this is probably it.
2) Also, the cell must grow and some organelles (like the mitochondria) must also replicate before the parent cell divides. If organelles like the mitochondria did not replicate, then you would eventually end up with daughter cells that don't have enough mitochondria to support themselves.
