The formula for calculating half-life is t1/2 = (ln2 / λ), where t1/2 is the half-life, ln2 is the natural log of 2, and λ is the decay constant of the radioactive element. This formula can be used to determine the amount of time it will take for a specific amount of a ...

The invention relates to a method for calculating the short-half-life daughter nucleus bank deposit external irradiation dose of long-lived radioactive nuclide. The method includes the steps of judging a balance relationship built by a mother nucleus and a daughter nucleus according to an emission ...
The step-by-step examples for you are: Identify the irregular shapes. Divide the shape into regular shapes example (circle, half-circle, triangle, rectangle, and half-triangle) Calculate the area of all these regular shapes. Add the amounts to get the total figure. ...
An understanding of percent allows students to estimate to check whether their answer is reasonable. In this example, knowing that 35% is between one-quarter and one-half would mean the answer should be somewhere between 20 and 40. Recommended Worksheets ...

Real-life Application with Solution The following are a few examples of reflex angles around us in real life. 1. Suppose you open a book slightly; the smaller angle between the pages is acute or obtuse. Now, think of the larger angle on the other side of the pages. That larger angle ...
Calculate the volume of a water cylinder with total height 1m, diameter of 40cm, and whose top section is hemispherical (half of a sphere). You first divide the shape into two sections, a cylinder and a hemisphere. The volume of a sphere is 4/3 ×π× radius3. In this example the ...
