    alright nice, but i dont know.. StoneBridge kind of seemed really knowledgable, so im feeling something is wrong , although it makes alot of sense to me.

    I think you need to review non-inverting amplifiers.

    *PHEW* Yes that makes more sense. The user "StoneBridge" really seemed to argue alot that this is wrong. I wonder about his point of view.

    because they do not want you to alter the circuit. Increasing resistance does increase smoothing!

    Simple, no contradiction. Both cases, the capacitor is parallel to the load. Increasing capacitance of capacitor parallel to resistor Increasing resistance of resistor!

    The B-scan technique basically combines a series of A-scans, taken from a range of different angles, to form a two-dimensional picture. As before, each A-scan corresponds to a single ultrasound pulse being emitted by the transducer and producing a series of reflected pulses from boundaries...

    Ill just pretend, i didnt see that... haha joking :P No that attachment is the voltage across the resistor and across the diode in half wave rectification! graphs you drew are correct as per mark scheme. congragulations but you wont be using them in the exam haha btw , questions of the full...

    same thing, a longer piece of wire wont make a difference.

    An increease in electric potential of particles does not necessarily mean increase in volume i.e work done by gas, right? Evidence of this is that ideal gas exert work on atmosphere but have no electric potential energies.

    Yes, thats what I found too. That means they wont ask us for an experiment for particle nature of electrons, and may you please confirm that the milikan's experiment does not show evidence for particulate nature of electrons i.e just quantisation of chare? Please be informed that the diagram for...

    Btw thank you for the correction, much appreciated !

    you are absolutely right that it provides evidence for particulate nature of light. but are you sure it doesnt show the particulate nature of electrons too? For example if there is a question that asks to design an experiment to prove particulate nature of electrons, What experiment do we draw...

    I thought milikan's showed the quanitsation of electrons?
