It is about 4 and a half months.
20% of 137= 20% * 137= 0.2 * 137= 27.4
137 = 137/1 in fraction
What does 137 round to why does 137 in tens around to
137 + 1/2 = (137 + 137 + 1)/2 = 275/2
137 / 2 is equal to 68.5
The half-life of cesium-137 is about 30 years. This means that it takes 30 years for half of a sample of cesium-137 to decay into a more stable element.
137.5/1 = 275/2
It is about 4 and a half months.
No, iodine-131 is not more stable than barium-137. Barium-137 has a longer half-life (approximately 2.55 minutes) compared to iodine-131 (approximately 8 days), making it more stable.
Physical or chemical properties are unrelated to the half-life of an isotope.
After 90 years, about 0.5 mg of cesium-137 would remain since cesium-137 has a half-life of about 30 years. This means that half of the initial amount would have decayed in 30 years and another half in the next 30 years, leaving around 0.5 mg after 90 years.
It will take two half-lives or about 60.34 years for three-fourths of a Cs-137 sample to decay.
86 miles is approx 137 and a half km
There are 137 feet in 137 feet.
The factors of 137 are 1 and 137, because it is prime.
The half-life of Cs-137 is 30.08 years, so 0.0038 would remain after 241.84 years.
