Here is something which helped me a lot when I was solving circuits
"Analyse how he current flows.If you find the same current going into different resistors they are in series,If different current flow flow through them they are in parallel"
To begin with
Draft ; It is the distance between the waterline and the bottom of the ship(hull)
That should help you .And looking at your work it seems legit
Be sure to check your calculation
This post is not about a homework problem but about a derivation
When i was flipping through a physical chemistry book I found a formula which looked like
How ever I am clueless to what it is
Can anyone explain what it is for
And possibly Derive it
Thank you

Is the question asking the concentration when the system has reached its half life
Can use the half life formula?[/B]The Attempt at a Solution
So
1/cT + 1/co = kt
1/(4 *10-2) + 1/x = k(half life time)
Is this the right approach
Please help me...
