Radioactive carbon-14 has a half life of 5730 years. suppose a peice of wood has a decay rate of 15 disintegrations per minute. how many years would it take for the rate to decrease to 4 disintegrations per minute?

Explanation:

Two important formulas in radioactive decay are

1. Calculate the decay constant k

2. Calculate the time

fe 55.85 g/mol and h2o 18.02 g/mol.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
