JMSS 2014 Testing Talk!

[SKGUN11]

Hahaha well i am quite confident with my maths (adveraged high-adverages- is that good enough?) from JAC
and i have began my year 9 science revision... guys do you actually know how much i need to know for science?? Like should i look at some VCE Chem/Physics?? (LOL I can just scavenge off my elder brother)
Hahaha anyways, lets continue with the Science Trivia...
a. what is an endothermic reaction?
b. if this atom have 1 electron on the out most electron, which group does it belong to?
LOL ask away guys...

a) When a reaction releases energy into the environment.
b) Group 1

[waftj]

a) When a reaction releases energy into the environment.
b) Group 1 Correct

Hahaha other way around SKGUN, Endothermic is when energy is taken in from the surroundings
Exothermic is when heat is transferred from the surroundings
Dw man, i thought u were correct, until i check my notes... hahahaha
I am freaken worried, because i don't know how hard the test will be or how smart are my competitors!!

[Hannibal]

Last time I'll ever have to undergo three hours of mental torture at JAC... Yay .

Few more questions:
What is the genus of homo sapien?
Does light travel slower in diamond?
What are three differences between light and sound?

HAHAHA YAY!! Just giving you the heads up, the science comprehension for test 20 is stupid. Tutor told us some of the questions do not have the right answers -_-
b. Light travel slower in diamond due to diamond have a greater density. Diamond is an example of total internal refraction. That is the exit angle is greater than the critical angle.
c. differences include:
1. sound may not produce reflection/ refraction- only with light
2. only sound produces compression and rarefaction
3. sound is produced via vibration while light is produced via electromagnetic radiation (eg. the sun)
HAHA correct me if i'm wrong

A few more questions:
a) What is the purpose of a fuse within every household?
b) Who mentioned about 'natural selection?'
c) Which Newton Law supports that you will keep moving if the car suddenly stops from constant acceleration and that the passenger wasn't wearing a seat belt?

Not sure about a)
b) Someone with a last name of Darwin I think ;O
c) The third law, because it states that every action has an equal and opposite reaction. As the car stops, you are sent flying forwards (I think)

You were right by the way! The first question was homo, with sapien being the actual species name .

Few more :

#1 - Where does the gas exchange of oxygen and carbon dioxide happen in a plant?
#2 - What is the electron configuration of Fluorine?
#3 - What are periods and groups in the periodic table?

a) purpose of a fuse is to control amps and prevent a possible fire
b)i have no idea
c) first law inertia

#2 - What is the electron configuration of Fluorine?
#3 - What are periods and groups in the periodic table?

a) The purpose of a fuse within a household or even a car is to open an electronic circuit when current flow exceeds a certain amount.
b) correct- Charles Darwin to be exact
c) tbh, i actually don't know the exact answer- which is why i posted it. Because don't forget you have to take in a count that f=ma (change in acceleration caused by forces)

#1- hum... not quite sure. (something to do with chlorophyll i think??)
#2 first shell 2, second shell 7 (so basically '2,7')
#3 period are horizontal across, group are vertical (used group to calculate the electron configuration)

[waftj]

a) purpose of a fuse is to control amps and prevent a possible fire correct :DD
b)i have no idea
c) first law inertia Thanks man, but can you explain, because i don't really get the theory of Newton Law

[Scooby]

#1 - Where does the gas exchange of oxygen and carbon dioxide happen in a plant?

Gas exchange occurs through tiny pores in a plant's leaves, which are called stomata. Carbon dioxide is taken into the leaf and used as a reactant in photosynthesis, while oxygen (a product of photosynthesis) is released from the leaf. The leaf might also take in oxygen from the air and use it for cellular respiration if photosynthesis is occurring to slowly to sustain it

ok so with the seatbelt thing... newtons first law of motion.. inertia an objects resistance in motion depending on its mass.. basically yeah all the laws contribute but inertia is the one that supports that statement the best. so the passenger will continue moving at a constant velocity until a force "x" (being the windscreen) stops them and thats sort of the third law, but the main idea of the car stopping suddenly and the passenger flying forwards, is the passengers resistance in motion.. which is inertia hope that makes sense I ramble a lot

Hahaha thankyou

[Rilin]

wow nice job. There are answers, you need to go to the main website.

Better correct myself then 

Edit:
Turns out I got 44 / 50. Yay!

[Elisha913]

Hahaha thankyou

no worries for the exam thing we have to be at caufield for 8:30 right?? did you guys get like gate/seat numbers or anything??

I'm not exactly sure where I saw this, but your parents (or whoever's email you put in when you applied for the tests) will get an email around Wednesday or something giving you all the details about the testing (like what you need to bring, times, etc.)
