GENERAL CALCULATIONS IN RADIOACTIVITY

[NurseBright]

Hey Guys😀
For QUESTION 3 On Radioactivity
Given(to) and Half life (t1/2) are both expressed in time units which can be seconds, minutes, hours, days, weeks, years. When solving any practice question at all you should have in mind that both of this parameters must be in same units when solving Questions. Like you can see in question 3 the value for given time(to) was 64 mins then when i solved for half life(t1/2) the answer gotten was still expressed in min. If the given time(to) in the question was in seconds the answer for half life(t1/2) will be in seconds

The same applies to all time units

Hope this is clear Now

Sorry sir, please in radioactivity, which unit will they give the time in?

Seconds, Minutes or Hours?

[patriciaomorodion]

Pls sir why didn't you use N1/No =(1/2)to/t1/2? You used 2 raised to the power of t initial over t half instead of 1/2 raised to the power of t initial over t 1/2. Pls reply

[the_krtor]

What is the difference if I jus divide the t nut over 2??
