A RADIOACTIVE NUCLEUS HAS A HALF-LIFE OF 20 YEARS, STARTING WITH 100,000 PARTICLES, HOW MANY PARTICLES WILL BE LEFT EXACTLY AT THE END OF 40 YEARS
A. 75,000 particles B. 35,000 particles C. 25,000 particles ✓ D. 50,000 particles The answer to the question is: C. 25,000 particles The decay of a radioactive nucleus can be described by its half-life, which is the time it takes for half…
A RADIOACTIVE SUBSTANCE HAS A HALF-LIFE OF 3.8 DAYS, CALCULATE ITS DECAY CONSTANT.
To calculate the decay constant of a radioactive substance, we can use the equation: λ = ln(2) / t½ Where: λ is the decay constant, ln is the natural logarithm function, 2 is the constant representing the ratio of the…
