Thermodynamics involving rods and heat transfer with conduction

AI Thread Summary
Two identical rectangular metal rods are welded end to end, with one side at 0°C and the other at 100°C, conducting 10 joules of heat in 2 minutes. The discussion focuses on calculating the time required to conduct the same amount of heat if the rods are welded side to side instead. Participants express confusion over the lack of specified lengths and areas, which are crucial for heat transfer calculations. The basic equation for heat conduction is referenced, but clarity on its application in this scenario is lacking. The conversation highlights the importance of dimensions in thermodynamic calculations.

ok...Two identical rectangular rods of metal are welded end to end (hot dog to hot dog) with a temperature of 0 Celcius on the left side and a temperature of 100 celcius on the right side. in 2 min 10 joules is conducted at a constant rate from the right side to the left side. How much time would be required to conduct 10 J if the rods were welded side to side {hamburger to hamburger}.

NO lengths mentioned which is what I am stuck on. I can get to 10*A/L=T2L/A through Q/T. K would cancel so would Q. not sure what to do with length and area as these are kind of important but not listed any ideas??

What is the basic equation you are using here? I don't see how you got to "10*A/L=T2L/A". It may be right, I just don't see how you got there.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
