easier said than done
term 1 assessments don't really count for that much tbh, if you get top 5 for everything in half yearlies and in trials you can hope to get 97 or 98+ and it depends on your school too. Your only good rank is bio tbh, everything else you need to toughen up.
Personally I kind of agree with you, I don't think that you should be doing this during your school exams. Your internal rank is very very important and you don't want to give that away, that being said don't be an asshole and not help someone in need, I'm saying you dont need to post your...
The question is,
3)V and V' are the feet of the perpendiculars from S and S' respectively to the tangent at P(X1, Y1) to the ellipse 4x^2 + 9y^2 = 36.
Prove that:
a) SV.S'V' = 4
b)V and V' lie on the auxiliary circle x^2 + y^2 = 9
I used a really dodgy method of doing this question, I put...
No, they just appear to be violated, for instance Newton's first law of motion will not hold true in a non-inertial frame of referrence for someone inside that frame of reference
You show that its an acidic salt by showing that NH4 is the conjugate acid of a weak base, thus NH4 will have the potential to donate a proton back to OH- as seen in NH3 + H2O -> NH4 + OH- so if NH4 has the potential to donate a proton, then in the reactoin NH4Cl + H2O -> NH3 + Cl- + H3O+...
Yes you're right both tubes will experience eddy currents which their direction will be in such a way to generate a magnetic field that opposes the direction of motion of the falling magnet. The reason the magnet falls down the vertical cut tube faster than the complete tube is because the...
Your answer is right, i got 1.33%, dont think that there is an imaginary line between something like 1ph and 2ph which determines the strength of an acid, the strength of an acid is purely whether or not it ionises 100% in water or not, idk if it was just me but i did a prac a few days ago where...
Yes, you react it with water and depending on what arrow you use will show which one is the better conductor, the HCl solution will have a single arrow showing that it'll ionise 100% in water whereas dissolving ammonia in water there will be a reversable reaction as ammonia is a weak base thus...
Fast food is not too bad, if you do your job right and have a good relationship with your boss you can improve your resume heaps from showing your a confident person, polite and welcoming and be able to handle conflict between customers with ease, I use to work at gloria jeans and there i had a...
Someone correct me if i'm wrong but you should only memorise a couple of strong acid/bases and a couple weak acid/bases
Strong acids -> HCl, HNO3, H2SO4
Weak Acids -> Citric acid, Acetic acid (CH3COOH)
Strong bases -> NaOH, KOH
Weak Bases -> NH4OH
yeah i dont know many bases lol
But the point...
