A heat conducting rod, 1.30 m long, is made of an aluminum section, 0.40 m long, and a copper section, 0.90 m long. Both sections have a cross-sectional area of 0.0004 m2. The aluminum end and the copper end are maintained at temperatures of 50°C and 260°C, respectively. The thermal conductivities of aluminum and copper are 205 and 385 W/m · K, respectively. The temperature of the aluminum-copper junction in the rod, in °C, is closest to:
Starting from x = 0 with no initial velocity, the acceleration of a race car is defined by the relation a = 6.8e- 0.00057x , where a and x are expressed in m/s 2 and meters, respectively. Determine the position of the race car when v = 30 m/s.
