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.

How is this Answer 3x?

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.

please help with part (ii)

helpaaa

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

View attachment 64128 help ANS is B

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).

 

[umerx_xwazdorf]

Is the answer B? View attachment 64138

Hi can u explain me how u got the answer as B

 

[umerx_xwazdorf]

Thank youuu,i suck at physics lol
