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
137.5/1 = 275/2
It is about 4 and a half months.
Iodine 131 has a half-life of 8.0197 days. Barium has no half-life. So no, Iodine-131 is not more stable than barium-137.
Physical or chemical properties are unrelated to the half-life of an isotope.
Since the half-life of cesium-137 is about 30 years, 3 half-lives would have passed in 90 years. The first half-life would leave .5 mg of cesium-137. The second would leave .25 mg, and the third half-life would leave .175 mg of cesium-137.
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.
12% of 137= 12% * 137= 0.12 * 137= 16.44
20% of 137= 20% * 137= 0.2 * 137= 27.4
