mass of liquid = 140 - 100 = 40 g

volume as shown = 60 cm ^3
therefore density = mass/volume => 40/60 g/cm^3

i think the markscheme is wrong

The reistance of one lamp is greater than the resuistance of 2 lamps in paralell - twice as great so the current will decrease

erm guys help! I seem to remember my teacher telling me one thing..and the mark scheme another.
Okay for graphs- or screens for AC and DC.

Hmm, how do we explain this.. But i guess an AC screen, would be like 'hills' one on top and one on the bottom? right?? Ok i know that..
but for DC? I know they 'hills' are all on the top, but are they next to eachother or are gaps left in the middle??? HELP

and exuse my amateur physics <3 haha
