Try Me:
A rectangular water tank (see figure below is being filled at the constant rate of 20 liters / second. The base of the tank has dimensions w = 1 m and L = 2 m. What is the rate of change of the height of water in the tank? (express the answer in cm /s)

Comments : Woo Nicholas rocks.
lol kidding, very simple layout, answers easy to obtain. Just use pink lol, like Kezia says, What the pink? xD
ans:1cm/s
easy due to diagram
colour and layout should change, seek more help from experts such as bill gates or the school technicians, more organization because its very messy now
EDIT: DONT* use pink lol, my other comment said USE PINK =(
ANSWER 1CM/S
1 cm/s
length=2m=200cm
breath=1m=100cm
hieght=?
dv/dt=20litres/s
=20000cm cube/s
area=200x100=20000cm squere
dh/dt=20000/20000
=1cm/s [ anwer ]
1cm/s
v=lxwxh
v=200x100xh
v=20000h
dv/dh=20000
dh/dt=dh/dv x dv/dt
1 litre =1000cm^3
20000/20000=1cm/s
websites are mundane, unable to capture attention but still its a very gd effort overall. maybe can try tying in with the edulearn thing. or enlist the help of other teachers to find other relevant websites

actually i donno how to do because yesterday i never come. i ask amir to teach me. we lose to hong kah sec 3-1. so sad... i twisted my knee then i go massage luckily i never die yet..
dv/dt= 20000
find dh/dt
vol of tank =W*L*H
=100*200*H
=20000H
dv/dh=20000
dv/dh*dh/dt=dv/dt
20000*dh/dt=20000
dh/dt=1cm/s
V=W*H*L
=100*H*200
=20000H
dv/dt=20litres per seconds
=20000cm^3 per seconds
dv/dh=20000
dh/dt=dh/dv*dv/dt
=1/20000*20000
=1cm per seconds
Find dH/dt= dV/dt/w*L
= 1cm/s (ans)
1cm/s
it is very convenient because we casn now try doings problem sums in a better enviroment(air-con0. Hence i really hope to have more of this acttivity in the future. on top of that we can blog out doubts regarding the recent topics.
Ans 1cm/s
Ans:1 cm/sec
dv/dt= 20Liter/second
find dh/dt
volume of tank= 2H
dv/dh= 20000
dv/dt= dv/du x du/dt
20000 x du/dt= 20000
dh/dt= 1 cm/s
use other layouts, a little tedious to type out the solutions. Clues for the given question and links are helpful.
the answer = 1cm/s
the web link is very useful for me to know & understand what are the steps to solve the converting rate qns ...
Ans:1cm/sec <<-- confirm correct!! Dont ask mi y -.-
W=100
L=200
Base Area=20000
dh/dt=20000(1/20000)
=1cm/s
answer: 1cm/s (:

omg, why pink?
pink is SO last year (:
its okay having this kind of stuff on the website.
ITS LIKE HOMEWORK ONLINE O_O
(oh, man.)
:D what the pink.
dV/dt=20 litres/seconds
=20000 cubic cm/s
dH/dt=dV/dtxdH/dV
V=WxLxH
=100x200xH
=20000H
dV/dH=20000
dH/dV=1/20000
dH/dt=dV/dtxdH/dV
=20000x(1/20000)
=1cm/s
Ans :: 1 cm/s
