Which of the following statements about opiates is false? A person taking opiates may develop a tolerance for them. Opiates have several medical uses, such as cough suppression. The effects of opiates include feeling energized and confident. Percodan and Vicodin are examples of opiates.

1. The temperature of a hot dog 2cm in diameter and 12cm long is initially uniform at 6 C. Once placed in boiling water (100°C, h=200 W/m²*K), how long does it take for the center of the hot dog (k=0.5 W/m*K, p=880 kg/m³ and cp=3350 J/kg*K) to reach 80°C? Use an analytical solution with a one-term approximation, i.e. n=1. 2. To sterilize a 4mm thick stainless steel (k=10 W/m*K, p=8000 kg/m³ and cp=450 J/kg*K) scalpel handle, you place it in an autoclave (121°C, h=100 W/m²*K) from room temp (23°C). How hot is the surface of the scalpel handle in 1 minute? Use an analytical solution with a one-term approximation, i.e. n=1.
1) Use the Gram-Schmidt process to convert [(0, 1, 1, 0)$^T$, (1, 1, 1, 0)$^T$, (0, 1, 1, 1)$^T$] to an orthonormal basis. Use the vectors in the order given.
