Hmm the answer is decrease , I'm sorry i was typing too fast and i messed up. I got it , thank you! srry for not replying quickly but I only check this place if i got troubles I am not a regular visitor

OH CRAP. I messed up. Area has nothing to do with it. Distance is increased , Capacitance is decreased so charge is increased. Thank man! Really appreciate it

Yeah , it's the surface area of the plate. Now can we get on with the question please , i have like 50 more to solve. (im not being rude I am just in a hurry) Studying for finals!

Right , distance is the main variable because it changes. Area , hmm I looked at the main equation so i assumed its a variable

Voltage is constant. while capacitance , area , charge are variables [SIZE=16px][FONT=PT Sans]

Voltage is constant. while capacitance , area , charge are variables

Homework Statement The plates of a parallel-plate capacitor are maintained with constant voltage by a battery as they are pulled apart. During this process, the amount of charge must... (decrease , increase , remains the same) Homework Equations C=Q/V C=E0(Area/Distance) The Attempt at a...

I GOT IT. Thank you. So as distance becomes tripled. capacitance becomes 1/3 and since capacitance is inversely proportional to voltage. so C goes 1/3 voltage is multiplied by 3 so 100*3=300V

Charge is not related?

Area and k (dielectric)

Area i believe?

Homework Statement A parallel-plate capacitor is connected to a 100 V battery until it is fully charged. The distance between the plates is d and the space between the plates is filled with air (k=1.0). Then, the battery is disconnected. If the distance between the plates is increased to 3d...

Thank you solved.Divide them both so x^2+1 / 1/x switch them to multiply so it's going to be x^2+1/x

The questions is asking me to find \frac{f}{g} basically , the question is asking me to find the answer , even though i know it, i can't get my head around it. the composite function is f(x)=x^2+1 g(x)=1/x we need to find foG (f of g) [composite functions].
