Physics unit 1 6PH01 discussion :)

you'll get 2/3 (which is pretty good for such question) i guess the grade boundary would be between 55-58. the most important thing is that our exam is easier than jan 2013

(0.26*3)*3=2.34kg/km (the distance is 3km, you have 3 cars so you multiply the 0.26*3 (emission for one car) and then you multiply by 3

They wanted the difference in Co2 emissions

i assumed for one car but i guess i did the ryt way so i ll lose 1 ryt?

 

[ALevel96]

You do as you've said before and then you calculate the emissions emitted if the car had been travelling at 18m/s and then subtract the two

thats weird :/

for the time question:
i forgot but i remember tht i found the power in Js^-1 then did a relation with tht 25% of energy to find time....

 

[ALevel96]

You'll probably get 2 or 3 provided what I'm saying is correct if not youll get 4

How did you approach the crisps question:

I did the energy in crisps * 0.25

1 minute = 15 extensions therefore one extension = 4 seconds

Do the crisp energy over the energy per extension to get energy per extension and then * 4 did anyone do similar

what were the forces on the free body diagram

 

[ALevel96]

Sorry not energy per extension the total number of extensions?

 

[ALevel96]

Whay

what were the forces on the free body diagram

What did you get?

 

[svenas]

Sorry not energy per extension the total number of extensions?

aha well, and what was the free body force diagram?

 

[svenas]

and why the ball will never be horizontal???

 

[jackoo123]

Whay

What did you get?

weight tension and i added inetria (arrow to the left) due to the acceleration :/

 

[ALevel96]

For some reason I added thrust dont know why

NO WAAAAY r u sure?

this shit is f*ckedup

 

[elephantina]

i forgot all my calculation answers but i guess u got most correct!
what u wrote for whether it obeys or not hookes law?

Which one was the range question? I keep seeing talk about the range but i cant remember doing any question related to it :/

 

[ALevel96]

Where i

Dayum Man It was hardest and length paper i have ever seen ! Paper was leaked at xtremepapers 4 hour before paper So tie your Asses up curves Gonna be high MadafuckAs

Where's your proof?

Bullshit! Anyone who uploads the paper before all the people actually done the paper , will get into a hell a lot of trouble if they catch him . So no.
