Title: I NEEED HELP
Post by: Galleria on October 22, 2010, 02:48:31 pm

Okaaaay
Hi .
They give this question in ATP ? like draw a graph vertical axis stufff ? i meaaan ,  how do we draw the time (vertical axis) against mass .. like do i put the values of time on x-axis ? or on y-axis ? lol . i know its a stupid question =D

AND

could anyone tell me where i can study electricity from ?
i mean
like how current, resistance, and voltage is affected in parallel, series . and also how do we know stuff like .. if a current moves through two lamps with a resistor of 1 ohm (in series), the current in them is same ? and stuff like that . its basic stufff but really important for my ATP!
pleaaase help!

Graph.

You don't need to draw those gigantic circles. :P I drew them large so that it is easy to spot the points.

You need to draw the best fit curve.

Does this help for electricity? http://s-cool.co.uk/gcse/physics/static-and-current-electricity.html

OH
THAT MAKES SENSE
LOL
I REVERSED THE AXES
DAMN
HOW DO I FIGURE OUT THE AXES??
:(

The axes is usually mentioned in the question itself, read carefully and immediately label the x and y axis.

Regarding the scales, first select a range which fits the graph, then select the values with which you are comfortable plotting with.


Why not? This one is really helpful :: http://s-cool.co.uk/gcse/physics/static-and-current-electricity/basic-circuits.html#current-voltage-and-resistances
