Previous Question: The total energy of a black body radiation source is collected for five minutes and used to heat water. The temperature of the water increases from 10.0º C to 11.0ºC. The absolute temperature of the black body is doubled and its surface area halved and the experiment repeated for the same time. Which of the following statements would be most nearly correct ? (A) The temperature of the water would increase from 10.0º C to a final temperature of 12º C (B) The temperature of the water would increase from 10.0º C to a final temperature of 18º C (C) The temperature of the water would increase from 10.0º C to a final temperature of 14ºC (D) The temperature of the water would increases from 10.0º C to a final temperature of 11º C Next Question: A radioactive nucleus A has a single decay mode with half life τA. Another radioactive nucleus B has two decay modes 1 and 2. If decay mode 2 were absent, the half life of B would have been τA/2. If decay mode 1 were absent, the half life of B would have been 3τA, then the ratio τB/τA is
