Lol, I'm sure it can be anything but the meaning in the video game 
anyhow, I still don't get how to draw it :$ , the problem is, sometimes the diagram becomes a must, so no escape from drawing that...!
I've tried to search it on youtube to see how to draw that, but I didn't find it.... :'(
Help... Plz...!

i
yes it is a metaloidis Antimony a metalloid ? I've looked it up in many places i got different answers but most of the websites said its a metalloid ....my teacher doesnt agree ....so is it or is it not ? thanks

stable equilibrium is when all the forces on it is balanced and its in a fixed position, during unstable the equilibrium the forces are not balanced thus the object falls or moves, nuetral equilibrium is moving is when the object.

It’s quite an easy question, you see.Lol, I'm sure it can be anything but the meaning in the video game

stable is ,for example, u! you can walk widout any problems...u dont just fall of due to ur huge weight do u?
neutral is for example a ball.......its centre of gravity is always the same no matter where it is kept,,,its always the centre..which is the centre of gravity
...now unstable is like u ,,,but upside down,,,u will fall off right? why>? because u r unstable,.,,,ur centre of gravity will make u fell.,......
i hope u got it

a) i) draw a normal at AB in which the normal is 2cm away from A , then the point G is the where the normal meets DC , while F is the point where the normal meets AB
ii) using your normal , draw the incident ray 30 degrees from the normal
b) i) join p3 and p4 then continue the line till it reaches CD
ii) measure distance between G and H
iii) join H and F
iv)measure the line you've drawn at (iii)
c)i) measure the distance between G and k
ii) measure distance between F and K
iii) use the formula given and solve it
hope that helps , ISA i'll upload the diagram too

Hey guys, Wassup?
Would you have a look at question no. 9 in paper 1 physics Nov. 2005?
I don't get how come hydroelectric power station isn't produced from steam?!

There is no use of steam in hydroelectric power station....

^ Hydro electric power stations use water to generate electricity.

Geothermal, nuclear and oil-fired all use the same concept to generate electricity. The three techniques tend to produce heat, evaporating water and using steam to move the turbine's blades. Hydroelectric, however, is building dams with turbines within them. Water flows downwards through the dams, moving the turbines along with them, generating electricity.
Pls help me solve this question
I know its rather hard but just tell me what you think is right please...
A uniform metre rule of weight 0.9N is suspended horizontally by 2 vertical loops of thread A and B placed at 20cm and 30cm from its ends respectively. Find the distances from the centre of the rule at which a 2N weight must be suspended:
i) to make loop A become slack
ii) to make loop B become slack
Draw a diagram. Makes it clearer and easier to solve.
(the weight of the meter rule acts from the middle of the rule, because the rule is uniform)
i) If loop A is slack, moment around loop B=0; s = distance from B;
.: 0.9N(20cm) = 2N(s)
s = 9cm from loop B, towards the near end.
ii) If loop B is slack, moment around loop A=0; s = distance from A;
.: 0.9N(30cm) = 2N(s)
s = 13.5cm from loop A, towards the near end.
