2(x+5) + 1 = 7 + 2x. Please help.
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

What is this??2(x+5) + 1 = 7 + 2x. Please help.

Because area under Force extension graph is always the work done in stretch the wire, given no plastic deformation has occurred. If plastic deformation occurs then the area under the graph beyond yield point, is the energy used to permanently deform the wire
Oh there is not solution. I got confused.This equation is not correct I guess, there's no solution. Is there a question about it?
That's a galvenometer and it a very sensitive device, upto 0.001A
There is no problem with the word 'infinite' but I just wanted to ask that why this option is not correct although it is possibleIt's a slight inaccuracy from CIE I believe. Instead of "infinite", you should interpret as "very large".
Ohh right!That's a galvenometer and it a very sensitive device, upto 0.001A
Ita resistance is almost negligible!
The correct answer is B!
Thankss!!Is it D?
If so then:
The equation used will be F=ma, Density=M/V and v=s/t
so M=Density*(A*s/t)
M=kgs-1
F=M*v
F=kgms-2
F=Density*A*v^2
I think there are about 3 methods to attempt this one.How to do this? I did it just by comparing their units but I want a proper method if anyone could help plz

Intensity is directly proportional to amplitude squared.
may god bless youIntensity is directly proportional to amplitude squared.
The equation becomes I=A^2/x^2 which can be simplified to I=A/x
At P: I=8/1 so intensity at P is 8 micro meter
At Q: I=8/2 so intensity at Q is 4 micro meter(D)
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
