One of the first scientists to theorize that heat is caused by the motion of objects or particles was Abū Rayhān al-Bīrūnī, who lived in the region of modern-day Iran during the 11th century. In addition to his studies in physics and mathematics, al-Birunī was extremely interested in the different cultures of his time. Because of his detailed study of peoples and cultures, he is considered by many to be the "father of anthropology." About 600 years later, an English scientist named Robert Hooke also argued that heat is caused by motion. Hooke made many discoveries in physics, but he was also an accomplished architect and surveyor. He applied these skills to help rebuild London after the great fire of 1666. The above example suggests that A. scientists with different backgrounds never reach similar conclusions. B. scientists tend to come from similar backgrounds. C. scientists possess varied talents and interests. D. scientists have similar talents and interests.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
