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.

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.

its A. Since pipe open at both ends 1st Harmonic occurs where 0.5lamda=L. 2nd Harmonic occurs where lamda=Length. Likewise 3rd Harmonic occurs where 1.5lamda=Length and finally the fourth Harmonic where 2lamda=Length. This gives u 50 cm so A

W acts ats at centre of radius which is 0.20m. Now to lift Weight, you would need upward force. To provide that upward force, you would need torque o a couple as there are two forces acting in opposite directions but you only require one of them to act in direction opposing the Weight (ACWM).
