    Physics: Post your doubts here!

    DragonCub I wonder what are those? Are those some model answers and you copied them? If so, can I know from where did you get them? Thanks. : )

    Physics: Post your doubts here!

    Ops sorry I thought you meant how to make sure that it was the terminal velocity. =/ Sorry about that. Continuing my previous reply, you basically measure the time taken for the ball to fall the distance AB by a stopwatch. This will allow you to identify the speed through the formula...

    Physics: Post your doubts here!

    What is your apparatus first? For instance, mine was that you drop a ball into a measuring cylinder ( or a large tube ) full of oil. I believe you can't be 100 % sure that a certain ball will reach a terminal velocity, however you can check it. You can mark two equal distances from the bottom of...

    Physics: Post your doubts here!

    I believe when the jockey moves to the left, the lamp would actually be shorted. Meaning that no current will pass through the lamp as there is a negligible resistance in the upper wire of the lower loop ( Indicated by the red straight line ). By the way, thanks for explaining why it will...

    Physics: Post your doubts here!

    U're welcome dude. ; ) Why did I add the 20? Well, let's think of another circuit with only a 12 V cell, a 60 ohm resistor and a 20 ohm resistor all connected in series. How would you calculate the resistance on the 60 ohm resistor? You'd say that the 12 V is shared with all the resistors in...

    Physics: Post your doubts here!

    Well I think your formula only works if there is no other resistance in the circuit ( like the 20 ohms of internal resistance ) ... Since the whole of the line would actually have a P.D. of 12 V so AB/AC into 12... This example is actually somewhere on the site's revision pages. The last one in...

    Physics: Post your doubts here!

    It is called the "Potential Difference across the resistor ". So if 1 end of the resistor has a potential of 3 V and the potential difference is 6.75, then: 3-x= 6.75 x= 3 - 6.75 Concerning the potential divider question: I'm not entirely sure of this answer but I understand that since the...

    Am I taking too many subjects?

    Thanks all :3... And abcde, I live in Egypt, you can go to university with 1 A Level only! And I wasn't talking about the minimum subjects I'm just wondering if taking those 3 Subjects in one June Session would be tough :\

    Am I taking too many subjects?

    I was wondering if taking Phyiscs A Level, Maths A2 and Biology AS would affect my concentration and therefore grades. Please tell me what you guys think and your experiences and such. Like what is the maximum number of subjects you took and what were your grades. Thanks :)

    I believe you can show them the stars in the transition menu through print screening them. Stars normally appear on the slide pane on the left when you apply them in the transition menu :\ But they won't appear if you print the slides normally...

    ICT Website Authoring Question

    Hello everyone, I have this question in mind and I hoped someone would answer me. See in the old practical past papers of ICT (2003-2006), the website authoring part usually contained a heading, a menu on the left and a table on the right. You see I can't seem to do the table on the right of...

    pls help in powerpoint2007

    Oh Oh I got what you mean. Look those star actually appear when you apply a transition! You do it like that : 46) To show the transition page, click on View ---> Slide sorter. You'll see your various slides in one page. Click on Slide Show ---> Slide Transition. Highlight all the slides...

    pls help in powerpoint2007

    Could you please link the Mark Scheme and the Question you're talking about so that I get a clear view of what you mean?
  19. waleedsmz

    Hello... Yeah...

    Study tips: 1- Make sure you get enough studying time as well as fun time! Having a better mood helps in studying! 2- Make sure you have a mark scheme ( You can view the mark schemes on this site too ) for every subject you're taking. It will help you find the most reliable answers and know...

    Help pls ICT students

    As far as I'm concerned there is no layout called "text and bulleted list". The layout which does that is called " Title and Text " I think. ( Someone correct me if I'm wrong )
