Two cylindrical rods are identical, except that one has a thermal conductivity k1 and the other has a thermal conductivity k2. as the drawing shows, they are placed between two walls that are maintained at different temperatures tw (warmer) and tc (cooler). when the rods are arranged as in part a of the drawing, a total heat q' flows from the warmer to the cooler wall, but when the rods are arranged as in part b, the total heat flow is q. assuming that the conductivity k2 is twice as great as k1 and that heat flows only along the lengths of the rods, determine the ratio q'/q. express your answer as a number with no units.

Answertraveling around a circular trackexplanation"traveling around a circular track" is the best answer as you could be traveling around a circular track at a constant speed. your velocity would therefore have the same magnitude but will always be constantly direction. since acceleration is the rate of change of velocity, the rate of change will only involve the direction of velocity and not the magnitude.wrong choices: "an object at rest" does not accelerate at all"increasing speed while traveling around a curve" means that the acceleration will not be constant due to only change in direction; it will be constant due to both magnitude and direction"an object in free fall" does not necessarily change direction
