Physics practical grams or kg?

[DARK DRAGON]

can u tell me hw much we lose for if we had not plot the graphs..i hurry i forgot to see marks ..

4 marks

 

[Abhishek Solanki]

r u sure we only lose 2marks if we had not drawn the graph

 

[Sarmad Furqan]

r u sure we only lose 2marks if we had not drawn the graph

have you written the scale and marked the both axis with units??

 

[Abhishek Solanki]

yeah my point on the graph was not in straight line nd rest all things was done ..only points were lying here nd there on the graph

 

[Sarmad Furqan]

yeah my point on the graph was not in straight line nd rest all things was done ..only points were lying here nd there on the graph

then you'll lose only 2 marks maximum..just chill man..

 

[xhizors]

what about k mine was near 1

 

[Sarmad Furqan]

what about k mine was near 1

just chill it varies according to the position allocated to the student...e.g mine was different as i was standing under an air conditioner..

 

[Abhishek Solanki]

thx alot ..

 

[DARK DRAGON]

same lol the chill of the AC gave me an idea for the error

 

[Abhishek Solanki]

k value was 478.22 sumthing

 

[DARK DRAGON]

k value was 478.22 sumthing

what thats so high mine was 0.09

 

[mujtabashahnawaz]

k value was 478.22 sumthing

yeah

 

[hussamh10]

Mine was negative too!

Mine was negative too and i am 100 percent sure its righy!!!

 

[hussamh10]

yes the gradient is negative

yea the gradient was negative because of 1/M

 

[mujtabashahnawaz]

Mine was negative too and i am 100 percent sure its righy!!!

I am also 100% sure

 

[oldfashionedgirl]

so when the mass increases the h increases so how can the gradient be negative

the height was decreasing with increasing weight :O

 

[mujtabashahnawaz]

the height was decreasing with increasing weight :O

yeah it was decreasing

 

[oldfashionedgirl]

mine was negative too but every other kid in the school had a postive gradient =[

then don't worry beacuse even here at xtreme papers u'll note that most ppl got a negative gradient

 

[oldfashionedgirl]

I even have my values and the table and I keep redrawing it.. it doesn't make sense how people got a positive gradient.. anyway what was p and q?

p was equal to the gradient you calculated while q was equal to ur value of y-intercept

and btw ppl, anyone who calculated the y-intercept from the equation of y=mx + c, then its really not possible for ur gradients to be positive since a positive gradient would give a negative y-intercept and the y-intercept obviously wasn't negative since there were no negative values used in the graph

Phew XD That's exactly what I kept tellin all the phys teachers at school who refused to believe that Everyone did it wrong and I did it right =]
