Yes you can although i suggest putting the ruler outside and measuring between the top part of the bottom wooden block and the bottom part of the top block.

Your welcome Eisya

In paper 6, the mark scheme in some years prefers using cm, and in others, only mm.
For example, when measuring u and v in a lens diagram, do we use cm or mm?

Thanks alot

bcoz i got confuse with this too...

[haris94]

no, they wont cut marks
unless it is specified which unit to use

It doesn't matter they'll put them both correct (whether in mm or cm) BUT if you want to use it in some equation you better make sure all the measurements are in cm or mm .

i neva said i made up the ques .. how does it matter.. i think i had at somewhere at the back of my mind .. =)

Right, isn't the graph for direct current, i.e the voltage-time graph, a straight line.

*bump**bump**bump*

There was such a question here earlier.

[Vin]

yup dc graph is straight .. __________________

*bump**straight line at bottom**bump* . is wen ac is rectified ..
