    Two capacitors are connected in parallel

    OK I GOT THE ANSWER FROM http://en.wikibooks.org/wiki/A-level_Physics_%28Advancing_Physics%29/Capacitors

    Two capacitors are connected in parallel

    Why distance is important in capacitance We know that capacitance can be calculated by the formula C=εA/d where 'd' is the distance between parallel plates. But why distance should matter? Can anyone explain please. Thank you.

    Thermal Properties of Solids and Gases Problem

    Please help. When a ring heated why it expands only outward? why not inward also making the hole smaller. Thank you.

    Standing Waves

    Don't they die out?? Two waves traveling in opposite direction should die out according to super position principle (Zero amplitude). Then how standing waves are produced? Is this not a contradiction? Please help. thank you.

    Surface waves vs longitudinal waves

    Thank you so much for your attempt. I am sorry, I am not convinced though...

    Surface waves vs longitudinal waves

    in fluid only longitudinal waves propagate but in Ocean water both transverse and longitudinal waves propagate. Does that mean Ocean water is not a fluid? I am confused. Can anyone explain please.(Longitudinal wave is the evidence for earth core is liquid)

    Simple Harmonic Motion vibrations

    Amlitude application of car When amplitude of SHM is constant(assuming no friction) why this amplitude is analogous to car springs displacement? Because after force applied car spring stretches (in real applications) and then displacement continues to decrease over a period of time. I am...

    Water Pressure

    in bernoulli's equation P+ρ g h =constant , are P and ρ g h different ? aren't they the same? thanks.

    Ice should sink?

    Oh,Water can be liquid at 0°C. that makes sense. Thank you so muchhhhh.

    Ice should sink?

    Yes, the same chart I posted above my friend. Water density at 9C is 0.999781 g/mL and at 0C is 0.999841 g/mL. So clearly ice denser as per that chart. So shouldn't ice sink? Thank you and sorry to bother you. http://www2.volstate.edu/chem/1110/Density_of_Water.htm [Broken]

    Ice should sink?

    No context my friend. I was reading a physics book and curious to know more about it. so, you think that ice is less denser than water of any temperature. Is that correct? thank you.

    Ice should sink?

    Thank you for your time my friend. Do you think that water of any temperature is denser than ice? For example which is more denser? ice(0C) or water(20C)

    Ice should sink?

    ice float As per any density-Temp chart or graph I found online giving unique info and that is ice is denser than water at temperatures more than 9C. Please be specific about temperatures.
