H =\DeltaQ/\Deltat = kA((TH - TC)/L)
L = 5.85 cm
But, does this help me in anyway?
S = Q/T
Am I supposed to figure out the entropy inside the furnace (Q/175 deg C) and add/subtract it from the entropy on the outside (Q/42 deg C)?
Homework Statement
A large factory furnace maintained at 175 degrees C at its outer surface is wrapped in an insulating blanket of thermal conductivity 5.50×10−2 W/(m * K) which is thick enough that the outer surface of the insulation is at 42.0 degrees C while heat escapes from the furnace at...
Actually, this is all the information I am given to solve the problem. There are other parts to answer (but I've already answered them):
When does car 1 stop? -> At B
when does car 2 stop? -> At E
And when do they have the same velocity -> at D
This is homework help, but I think all I need to learn is how to read a VT graph properly. My professor uses MasteringPhysics.com and this is one of the questions from the site. The way it works is: the student has 5 attempts to answer a question before it is counted wrong and I'm down to my...
