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)
P=Density*g*hHelp?
Is it C?
Yes and why though?Is it C?
Ok this is a difficult question to understand. So the concept of this drink is that the child decreases the pressure on the top of the straw to 90% of the atmospheric pressure. This means there is a pressure difference between the air in the straw and the atmosphere of 10%. So the atmosphere applies a force on the surface of the liquid which pushes the liquid up the straw(due to the pressure difference). This is just so that you understand what happens, now onto the formulas:Help?
Only one field exists here which is electric. The electric field's direction is towards the right so the positive terminal is at the left and the negative terminal is at the right side. Since the electron is approaching the negative terminal, there would be a repulsion force. This would case the electron to decelerate to rest, so the speed of the electron would decrease. It would be a linear path since the electric field is acting horizontally, so there is no force acting vertically, hence the electron will move in a straight line.
