you almost got it u change the rate to a decimal so it will be .188 in ur calculations instead of 18.8

it looks lke almost everyone is behind by atleast half a chapter my schools done the following 1.moving about 2.electricity 3.world communicates 4.20-30% done of the cosmic engine and our teacher said where behind by 1-2 weeks

Yea i found this out lol, but u can upload pictures that are less 97.7kb or less from ur computer. This is what it said when i was trying to upload mine but it was 1.6mb

Yea i no this i was just using it as an example as water is a small molecule which everybody knows.

awww it didnt work

ill draw it with letters H(δ+) (δ+)H H(δ+) (δ+) / \ / H O(δ-) O(δ-) / \ (δ+)H H(δ+)(δ-) O H(δ+)...

Dipole-Dipole attraction occurs between polar molecules. e.g water (H2O) i drew a picture for u but its too big.

Hi, i was wondering if this is how you do the following question. Suppose x^3– 2x^2 + a ≡ (x + 2)Q(x) + 3 where Q(x) is a polynomial. Find the value of a. since u dont know Q(x) id say ud have to get rid of it. to do this i put P(-2) into the equation so then i got -2^3-2*-2^2+a=(-2+2)Q(-2)+3...

Re: maths preliminary yea my school has seperate but only 2 periods a wk for 3u

yea im doing 14 but im pretty sure im going to drop DAT I think 12 units will be better than 10 for the main reason that you have someting to drop back on incase something goes wrong

Re: maths preliminary This year in maths ive done he following 2u -arithmetic -algebra -geometry -functions -triginimetry -locus and the parabola (just started) 3u -inequalities -permutations and combination -angle between 2 lines -interior/exterior ratios -polynomials -circle geometry Trig...

ok lol. I think the basic info in the question was *1 virus per 50mL water *a carefull person hoses for 10 seconds and x amount of water comes out/minute (here i thought a carefull person would be able to avoid contact so the amount of water comes out doesnt matter.) *the person flushes a toilet...

lol. My chemistry teacher showed our class a few of these in term 1. But these a pretty funny

Well if it was 900 viruses that means 9L of water from the shower didnt hit him. Thats how i assumed it all hit him lol, so in my mind i was right but knowing my luck it'd be wrong. From the calculations i did i got exactly 1080 which was one of the answers.

Yea i assumed that the careful person got hit by all of the water in the shower. so i just did 2x3 minute showers at 9 litres a minute, changed it from ltrs to mls then divided by 50 because it was 1 virus to 50 ml of water. and i got 1080 viruses hit him/her. There could be debates over 1080...

Yea it wasnt to difficult i found the question Which 1 reacts the quickest (or somewthing like that.) the easiest (Fr+F)

I got selected from my school to do a science 1. It was called summer science school and it was located in ACT. To apply i had to go to a website and enter my details. Then i had to do an interview so they could select 6 people from 60 from my area. (I didnt go because i couldnt get to where...

yea do it if u feel u can do it. Im not to sure about doing it myself but my teacher thinks i can do it so ima give it a go. In half yearly i got 86% and i do approx 1-2 hrs a week for mx1. You can always drop it if it gets to hard so u may aswell give it a go.

Hey just wondering how many people did the chem comp and how you think you did. I think i did pretty good, not sure about some of those last q's tho

Do you mean no air resistance. because i think (not 100% sure) if u shoot a bullet straight up it wont come back down at the same speed coz of air resistance will limit its max velocity. But im not sure of the effects of air pressure because i have not done it in physics yet
