Hi friends,


Can u pls share yr answers 4 the follw qts:

1) Car windscreen - how can he c

2) In Forest how 2 get H20 with newspaper,string.....etc

3) Big elephant with big big ears n small ele with small ears - in forest

4) Rod b changed 2 greater thickness - effect of expansion

5) Y the nail cannot magnetised with northpole

6) Decomposition - how 2 increase?

Ok,I cannot do the second q u asked, and only one way for q6. :stupid:

My Answer:
1) Heating allows the water droplets on windscreen to evaporate,enabling him to have a clearer vision of the vehicles and pedestrians behind him.
2) Don't know.I just any how do. :stupid: :?:
3)Advantage: Ears have bigger e.s.a. , allowing the elephant to lose heat easily,keeping it cool.
Disadvantage: The rainforest is much cooler than the ___, it loses too much heat,and might die because it has not enough heat to live.
4)lesser than 210cm3. It is thicker.More heat isneeded to heat up the rod, so the expanxion is lesser.]
5) The north pole of magnet attracted the south atoms to one side of the rod,the other magnet did not have any atoms to be moved to the other side of the rod, so not sucessful.
6) I only know one way: add more decomposers and scavengers into the bin. Scavengers: To break down e smaller pieces of dead leaves into smaller pieces.
Decomposers: To break down e smaller pieces of dead leaves into simpler forms.

Just hope the answers above r correct.
