[Awesome12]

change was 34 and the shc was 4200

for second change was 54 i think

And how many marks was each part?

 

[afrolina]

what was the answer for that refractive index thing?

 

[Abdul Hanan]

Theory main -_-

speed time tha'
uniform acceleration wala part slope tha

 

[asadalam]

And how many marks was each part?

3 and 2 i think

 

[Ram97]

speed time tha

how do u make speed with uniform acceleration??? is it alwys increasing with time

 

[afrolina]

oh and for the waves question, one was greater than 5.6 another was less than.. am I right????

 

[Abdul Hanan]

how do u make speed with uniform acceleration??? is it alwys increasing with time

ok i dont understand u... sorry
but the graph wa first a line with positive gradient then horizontal line and then decreasing gradient line

 

[Abdul Hanan]

I don't remember.

Was it LIQUIDS are mildly higher in expanding vs solids
Or SOLIDS were mildly LOWER in expanding vs liquids

Konsi wording was there ( I know mine is the same - but U get the point )

solid/liquid one was mild
liquid/gas was not mild i.e high

 

[afrolina]

answer for one of the waves question was greater than 5.6 and the other one was less than 5.6. Am I right???

 

[asadalam]

ok i dont understand u... sorry
but the graph wa first a line with positive gradient then horizontal line and then decreasing gradient line

And the last slope was steeper.The distance was 15.6 m right

I don't remember.

Was it LIQUIDS are mildly higher in expanding vs solids
Or SOLIDS were mildly LOWER in expanding vs liquids

Konsi wording was there ( I know mine is the same - but U get the point )

Liquids slightly more expand than solids
Gas expand much more than liquids

 

[Abdul Hanan]

He is asking for that definition of uniform acceleration BELOW that graph.

oh...... that was "constant change in velocity over time"

 

[Abdul Hanan]

And the last slope was steeper.The distance was 15.6 m right

Liquids slightly more expand than solids
Gas expand much more than liquids

yes 15.6 and the other one too same answer as mine

 

[asadalam]

yes 15.6 and the other one too same answer as mine

Great minds think alike

 

[Ram97]

And the last slope was steeper.The distance was 15.6 m right

Liquids slightly more expand than solids
Gas expand much more than liquids

Distance 15.6
Wasnt it solids slightly more expand than liquids??

 

[asadalam]

Distance 15.6
Wasnt it solids slightly more expand than liquids??

liquids expand more,have weaker intermolecular forces

 

[Abdul Hanan]

Distance 15.6
Wasnt it solids slightly more expand than liquids??

liquid slightly more than solids....yes
gases alot more than liquids (not mild)

Please reply,
what was the answer for the refractive index question???????????

 

[afrolina]

Please reply,
what was the answer for the refractive index question and for the waves question, one was greater than 5.6 another was less than.. am I right????

Please reply,
what was the answer for the refractive index question???????????

Glass prism has a higher refractive index than air, which means light travels slower in there. When white light enters the prism, it changes direction because of the slower speed. Red and blue have difference wavelengths and frequencies so they change directions by different amounts. Due to this, the angles of refraction are different and they split up.

 

[Ram97]

liquids expand more,have weaker intermolecular forces

I'm asking did it ask from liquid to solid or solid to liquid cuz i dont remember that question
