The Unofficial HAKK "Holiday"

Today, the Hari Anugerah Kecemerlangan Kokurikulum (HAKK) was held. The event started at 7.40 am (was it?) and ended at around 9.30 am. Lessons continued as usual shortly after. Well, at least those who were absent didn't waste their time enjoying their little "holiday" right, Ethan?
Since there was quite a number absentees today, I'll be posting today's homework here. So, those who weren't present, please take note.

Homework
Practice 1, pg 182 (Chapter 9: Differentiation)
DO ALL (Book 1)

Book 2 had been sent.

*Just a little summary of today's Add Maths lesson. Just in case you don't understand the explanation in the text book.

lim means limit
x --> n means "when x is approaching n" where n represent a constant (number) .

Anything after the limit and "x --> n" is called a function. Example: 1/(x+4) [refer to textbook]

-[-][-I'll refer the "limit", the "x --> n" and the function as a "function limiter". Keep in mind that this is not the official name of the "funtion limiter"-][-]-

So for Q1, construct the table and key in the function on your calculator and replace x with the constant. As in the case of the first question, x = 1, 0.5, 0.1, 0.01 and 0.001. The same thing goes for Q2. After you're done with the questions, write down the "function limiter" expression again and put it equal to the number it's approaching. As in the case of the first question, the answer is 2.

As for number 3, just substitute x in the function with the number that it's approaching. For example, "x --> n". In this case, substitute x inside the function with n and you'll get the answer.

That should be all. Hopefully the explanation above helps.

Physics Exercise 2.10


This is for those who didn't manage to jot down the questions in class earlier today. Solve the questions in your exercise books.

1. A crane lifts a load of 5000N through a vertical distance of 12m from a ship to the ground in 20s. Calculate the average power of the crane. [ Unit of Energy: Joule (J) ]

2. A rock of mass 4.5kg falls from a height of 14m to the ground. Calculate the loss of potential energy when the rock is 5m above the ground.

3. An electric motor lifts a box of mass 5.0kg to a height of 18m in 5s. Calculate the power of the motor.

4. A lift in a building can carry 15 people through a height of 10m in 10 seconds. The total mass of the lift and its passengers is 1500kg. Calculate the power of the lift.

5. A fat man of mass 100kg and a thin man of mass 50kg both ran up a flight of stairs at a height of 12m. Both the men took 10s to complete the task. Calculate the power generated by each man.

6. The graph in figure below shows the relationship between force, F and the spring extension, x.

Calculate the work done to stretch the spring from 8cm to 12cm.

7. An electric motor of a crane rated 500W can lift a load of 450N vertically through a height of 8m in 10s. Calculate the efficiency of the motor.

*Refer to your notebook if you're stuck at any question.

I'm out of ideas for the title....~~~ sienz

Haha, it's been quite some time since the last post, eh? I've been kinda busy with the new layout. Just a few reminders and notifications....

Biology
We'll be conducting an experiment on Wednesday. The experiment revolves around the concentration of solutions, I think. So, I'll advise you to bring a potato for yourself. Although you'll be in a group of 4, it'd be better if you just bring one just in case other group members didn't bring their share of potatoes. Just make sure the potato isn't too small. We need to observe what would happen to it. 

Ah, I just remembered there were still some of those who didn't get their Paper 3 exercises. The one on the erythrocytes.So if you want the exercise, come and see me. I still have a few more copies with me. And thats all for Bio.

Secondly is Physics
Yah, physics PEKA. Tomorrow's the deadline. Submit your PEKA tomorrow. Don't really have much to say about this. So, that's it lah. Oh yah, there's still another thing. Prepare a report on your rocket.

Next is Results Slip
If your name is listed here, please bring your Results Slip tomorrow.
a) Alvin
b) Veno
c) Vinod
d) Arina
Yeah, bring it tomorrow, kay? I only need 4 more. I've been holding 33 of these since the last 2 or 3 weeks, so please help me get rid of the extra load in my bag. XD

Chemistry
Those 10-12 pupils who haven't pass up your exercise book, please do so. The deadline was weeks ago. Chances had been given. Just don't take things for granted. What's the point of giving chances if you don't try your best to use it to the fullest? Ah and yes, summarise the notes on chemistry located below. Or just use this link if you're lazy.

Bahasa
Haha. Pass up your Karangan book tomorrow. The essay is about the Rumahku Syurgaku letter, if i'm not mistaken. So, finish it up and I'll collect it first thing tomorrow.

Add Maths
We'll be having extra class this Friday until 12:50 pm. So, inform whoever is picking you up that you'll be a bit late.

PJ (For boys)
Directed to all 4M/J boys. We'll be having PJ on Wednesday to finish up the SEGAK test. There'll be a bit of push-ups and sit-ups, i think. So, best prepare yourself if you feel like impressing some anonymous person. Isn't that right, Nic?

Science & Maths Society
The S&M society is organizing Explorace as part of their participation in the Academic Month. The race is open to all morning-session pupils. A fee of RM4 will be charged on each group and each must have only 4 group members. No more, no less than that. Further information can be obtained at the S&M notice board located on the ground floor of Block B. Or if you don't like walking to the board, you can always have the walking board, Parri, come to you instead. XD

I don't think I want to bring up anything about the Sport's Day. So, that's the end of the first post for the new layout and that's all until the next post comes, I guess.

Physics Ex 2.4 Compiled

I compiled the exercise so you won't have to scroll down to find the first part of the work. So, there it is lah.

Excercise 2.4
1(a) A lorry managed to travel a distance of 6km in the last 15 min. Upon nearing a traffic light, the lorry driver stepped on his brakes to stop his lorry. The speed of the lorry decreased uniformly and came to a halt after 3 seconds. Calculate
(i) the velocity of the lorry in the initial 15 minutes
(ii) the initial velocity of the lorry
(iii) the deceleration of the lorry

(b) A steel ball of mass 1 kg is dropped vertically from a table as shown in Figure 1(which habib will post later). A bucket of sand is put beside the table so that the steel ball can drop into it.

If the steel ball took 0.5 s to reach the bucket of sand, calculate:
i ) The velocity of the stell ball when it hit the stone.
ii) The height of the table.
iii) The deceleration of the stell ball if it managed to sink 10cm into the sand.
(consider: g = 10 m/s^2)

Okay, that's all for your exercise. Now just read page 8 in your Practical Book. Read, understand, conceptualize and repeat.

Welcome to March... Goodbye February 29th

I know... the title should have been used in the previous post but it was kinda messed up and i'm lazy to edit it  XD. -Back to formal language-

Welcome to March. A lot of activities awaits us this month, in my perspective at least. Sukantara is going to be held soon. So, please train yourself if you want your sports house to win. That should be it. The rest would be more effective in point form.

<----|Reminders|---->

1. Complete your Sivik project by tomorrow. I'm not so sure what would happen if you send late too anyway. So, just suit yourself.

2. Complete all your other homeworks.
---> Mod Maths - Assessment 1 corrections (Book ?)
---> Add Maths - Chapter Review Q1, 2, 9,11
---> Bio - I have no idea
---> Chem - Quick Review pg30. Do all of the Q's.
---> BM - Please complete your Karangan about water pollution and KOMSAS.

That's all for tomorrow, I think.

p/s: Arina.... I'm still waiting for the pics. Please send it before the holiday starts. Anyone who wish to speak up their mind or just want to post something good here (no nonsense, please) inform me personally at school. I'll send you the login details through your mail. That would be all. If you have any important requests or questions, please use the inquiries option.

I type you write!

I guess i have to do this after all...
Here's my BIO PEKA work.. copy first then reconfirm tomorrow. ( THIS IS JUST A GUIDDEE).
Don't need to do the variables, draw the diagrams and make sure you DO the technique.

Aim : To determine the structure and shape of the plant cell.

Problem statement : (do yourself, make sure it's a question and has a '?' )

Hypothesis : ( answer the question )

Materials : ( don't tell me you don't have the practical book )

Apparatus : ( uh.. the practical book? )

Technique : To examine the cell using light microscope.

( draw the diagrams from the practical book, for the procedure )

Procedure : (make sure it's in PAST PASSIVE form )
1) A scale leaf from an onion bulb is obtained as shown in figure (a).
2) (the rest do yourself thnx )

Discussion : ( do in paragraph form, don't need to copy the questions. Combine the answers together to make a paragraph )

Safety precaution :(do only lah just in case..I'll give one..)
1) make sure that no air bubbles are trapped under the cover slip.

Conclusion : (remember to put 'Hypothesis is accepted/not accepted )

DONE FOR PLANT CELLS, NOW FOR ANIMAL CELLS^^
The report for animal cells is very much the same with plant cells..
Just change the name of cells,the diagrams also change, the procedure.., iodine to methylene blue solution and the discussion..
Everything else is the same.

: Mod Maths : Reminders : Homeworks :

Apologies for the late post. I wasn't able to post yesterday because I was really tired. So here it is, for those who went to the counselling on the day the notes were given.

[Mod Maths notes]
*Continue after the notes on subsets in Venn Diagram*

4. The empty set is a subset of any set.

5. Every set is a subset for itself.

Example: 
<------->P = { a,b }
Subset of P = {a}, {b}, { }, {a,b}

6. The number of subsets for a set within element is 2ⁿ
Hence, n(P) = 2
-----=>number of subsets for P = 2²
<----------------------------------> = 4

Question : It is given that set A = { a, b, c}, B = { a, b, c, d, e, f}, C = { d, e, f} and D = {b, c, e, f}

a) Complete each of the following by using the symbol "¢" or "с"
  i) A __ B
 ii) C __ B
iii) C __ D
iv) D __ A

b) Draw Venn Diagrams to show the relationship between
 i) A and B
ii) C and B

c) State the number of subsets for set A and set D

set A = 2ⁿ
<->A = 2³
<--> = 8

set D = 2ⁿ
<-> D = 2^4
<-> D = 16

d) List the subsets for set A and set D

Subsets of A = {a}, {b}, {c}, { }, {a, b}, {b, c}, {a, c}, {a, b, c}

Subsets of D = {b}, {c}, {e}, {f}, {b, c}, {c, e}, {e, f}, {b, e}, {b, f}, {c, f}, {b, c, e}, {c, e, f}, {b, c, f}, {b, e, f}, {b, c, e, f}, { }

Universal Set

1. The universal set, ξ is a set which consists of all the elements under consideration in a given discussions.

Example: ξ = { whole numbers from 1 to 8 } 
<------->A = {3, 4, 5}



2. ξ = { letters in the word 'insect' }
> Q = { vowels }



Complement of Set

1. The complement of a set A (written as  A') is a set in universal set, ξ which contains all the elements not found in A.

Example: ξ = { whole numbers from 1 to 8 }
<------> A = { 3, 4, 5}



A' = {1, 2, 6, 7, 8}

2.  ξ = { letters in the word 'insect' }
> Q = { vowels }



Q' = { n, s, c, t}

Number of complements in set A

n(A') = n(ξ) - n(A)
<--> = 8 - 3
<--> = 5
___________________________________
: Homeworks :
*Those that needs to be done by tomorrow*

1. Biology - Do notes on Chapter 3.1 until the Simple Diffusion subtopic.
<------->- Exercises: Focus Prac 3.1 (pg 49). Answer in notebook.
<------->- Question 2: change the word 'active' to 'passive'

2. Mod Maths - Ex 3.2a Q6

: 2.1 Linear Motion : Notices : Homeworks

Apologies for the late post. As my excuse for the lateness is currently irrelevant, I shan't explain myself. Today's homework shall be posted below; prefects, please take note. Right below is today's physics notes and below the notes are the exercises.

Thursday<---->Feb 5, 2009
Chapter 2: Forces and Motion
2.1 Linear Motion
Distance and Displacement

1. Distance is a scalar quantity whereas displacement is a vector quantity.

2. Displacement is measured by the length of a s
traight line joining in a specific direction.

3. Displacement is the distance travelled in a specific direction.

*Please draw*

Example 1
If a boy takes 10s to finish each of the following paths AB. Find the total distance travelled, and the displacement in each case.



*Please draw*

Total distance travelled
= 2 + 4 + 6 + 8 + 8
= 28m
