felix00:
I don't care

like I asked u to, Rubbish!

felix00:
Dist=0.2m mass=0.5 V=40m/s
V^2=U^2 + 2as. V=0
-U^2=2as
(-40)^2=2(0.2)xa
1600=0.4a
a=4000
F=ma
F=0.5x4000
F=2000.
Ans=B

Friedyokes:
I think its b
1/2mv^2=FD
Substitute and solve nd ull get 2000

This is the misconception I'm talking about

Elastic potential energy = kinetic energy
Basically what this person said

Amethyst101:
Just worked it now, the answer is C.
1/2 mv^2 = 1/2 F e.

Energy in extending the catapult(1/2 F e) = kinetic energy of the stone (1/2mv^2)
Equate and get F

oh okay then ..thanks

a rock sample was added to cold dilute HNO3. the gas evolved was passed into a solution of acidified k2cr2o7 and the solution turned green. the rock sample contains?
Pls post your answer with reason.

I'm not sure of my answer. But I know the pituitary is the master gland and the pancreas doesn't stimulate............its just an insulin production site.

Stanley what's the correct answer?

yeah..sorry for taking long..
the answer isn't given in those options,that i did intentionally, LIVER is the right answer.
the liver stimulates insulin production but beta cells in the pancreas produce the insulin questions like this could be missed.

The rock sample contain a trioxosulphate(iv) and the gas evolved is sulphur(iv) oxide which is a reducing agent which changes the orange colour of K2Cr2O7 to green.

thanks. Helpful

anyone who has helpful notes on combustion reaction of certain compounds?

Felix u can post a screen shot of the result to prove them wrong......lol....na real lie mohammed.....no chills at all

Optimist1998:
Amazing work! Felix you the man

u didnt even ask me of mine

Drienzia:
lie Mohammed

why are u so jealous?? .....see the wicked name u called him self

Nuel25846:

Jealous? nah. I'm not a jambite so why should I? I think the lies I read on NL these days is appalling. Assuming he scored what he claimed. why didn't he add a screenshot to d post? at least, to verify the veracity of d claim

Felix is an intelligent guy....I don't see any reason why he would lie.

unless he wants to be the next minister of information and culture

Godhead4:
A ball of mass 0.1kg is thrown vertically upwards with a speed of 10m/s from d top of a building 10m high.. Neglecting air resistance.. It's total energy just before hitting d ground is?

(Post workings)

5joules....total energy = P.E + K.E but since P.E =O K.E = Total energy = 1/2 Mv^2 = 5J

if u are nt a jambite. please dnt comment here unless u have what to contribute. nuel25846 what was ur score

Sorry I had to cut in. @bold; Isn't that a question of choice? Besides, You didn't ask him for any proof.

didn't ask him for any proof because I know there's nothing to prove. if he indeed scored that high, then wish him well, to even score higher in the main exam.

Everytime I try to check mine they tell me there is no row for position 0. it seems if one doesn't submit before his or her time is exhausted u end up getting no score.
