    physics paper 3, harder than hard

    One Thing to say !! The Exam Was Harder than the hardest hard of the Hardes Nature !! WHAT THE HECK?? This Paper was the worst paper in the IG History... why is it our luck soooo bad ?? I came out of the exam Cying and so where few others, everyone did bad in my year, and we were all just ...

    but we don't know the diameter inorder to know how much it'll be after it halfed, so why you put the radias as 2 ??

    Why when we half it , it multiply by 4 ?? I don't get it

    But why when diameter halfed, area increased by 4 ??? and why you multiplied the old resistance with the area in specific ??

    Without air resistance, it falls at a constant acceleration. With air resistance, it accelerates at the bigining until air risitance is equal to the object's weight, causing a resultant foce of zero, it'll start falling at a terminal speed (constant speed) <--- After it accelerates in the...

    I believe it's the voltage ! Remeber, is series , the voltages across the bulbs add up to the voltage of the battary. and thus not all bulbs get same brightness In parallel, voltage is same across all bulbs, thus we get equal brighness and this is one of the advantages of parallel curcuits!!

    My book seems so different ! I think you're right, but for the relay, you meant electromagmagnetic operated switch ... right??

    Small question ! In LDR , when there is light and resistance falls, what happens to the voltage ? Increase or decrease? (is it proportional or not?) Same question for the Thermistor ! Thx

    Physics, Chemistry and Biology: Post your doubts here!

    Actually, you said the thermistor correct , but the second point you talked about is the relay switch, not a transisitor !! A transisitor, is a semiconductor device that works as a switch and has three parts, base, collecter and emitter. Usually it's used in LDR (Light Dependent Resistor) <--...
