Get back on this after 7 hoursNaa you can't say that!! Show a sample of your handwriting first
Before that I won't agree with you!
And uncertainty is another pointlessly important topic in A'levels
I'll get you easy-to-remember notes asap
For the second rule , when its a^m/b^n >> you meant to write MINUS right
it doesn't matter because originally our del(a) and del(b) both has a ± signFor the second rule , when its a^m/b^n >> you meant to write MINUS right
What about the notes on uncertainty ??it doesn't matter because originally our del(a) and del(b) both has a ± sign
considering that, evn if you write a minus sign, the ± cancels it out.
So, overall all we do is, take the sum and when writing the final answer simply put a ± before the uncertainty value

Q-9 b.. and Q-11 biii
Can anyone help me with these.
your 3rd question is similar to 1st question. Here instead of the ratio, you are asked to find the time taken to reach that ratio
If you have understood my answer to first question it's easy to find the result for third question. But if you still have confuson then let me know.
I'll skip numerical calculations for your 4th question
Consider Initial activity is A1
after time t, Activity reduces to (A1 x 1/10)
put the values in the equation of activity
you have already found decay constant in previous parts
now just put the values and solve it.
If you are still unsure or confused about any of the answers, then let me know
u got fx8991es-plus ??
