The attachment doesn't want to upload properly so I have provided a free a and a premium file host:
When link dies I try again. Feel free to email me at [email protected] for Fresh links or mirrors.
I personally prefer Rapidgator or 1fichier but I know many don't have a Premium leech like alldebrid or real debrid.

Also Since the material is copyrighted its best that its not hosted by the site.
Code:
Free File Host dropapk (Click slow download, Copy in the number ,Click download , Profit!)

How is this Answer 3x?

View attachment 66940
Hooke's law is F=k*x.
And in parallel we add the spring constant of springs.
So, initially: F=3k*x
Then, one spring removed and force doubled: 2F=2k*3x. Must simplify to F=3k*x, as it does.

Another way to look at it is:
Hooke's Law is f=k*x
By changes, new K is made 2/3 times original k
New F is made 2 times original f
As x is directly proportional to f and inversely proportional to k,
new X is 3/2 times * 2 times original x. So, 3 times original x.

I hope this helps.
