Oops, then u should have 7.5 uC on each capacitor since charge doesn't accumulate in a loop. Divide by capacitances to get voltages on each capacitor. That would be 7.5 V and 3.75 V for 1 uF and 2 uF respectively.

You're not using Kirchoff's law correctly. If the caps. are in series as you say, it should be V1+V2+V = 0 so that V1+V2 = -V. You now understand? Also use charge conservation laws: charge doesn't accumulate in a loop.

charge cannot accumulate in a loop so both capacitors should have equal and opposite charge Q. Q = CV so the voltage on each capacitor will be V = Q/C; The 1 uF cap. has twice the voltage as the 2 uF cap. following the above relation. This can only be 3.33 V for the 1 uF cap. and 1.67 V for the...

To be clear: zero temperature can be a relative concept. For example, when an object is not moving, it could be thought classically of as having zero temperature but this is not true as you know that your body temperature is about 37 degrees C. Absolute zero should mean all particles including...

X need not be a wavelength. X is the unit spacing in direct space and 2*pi/X is the unit spacing in inverse (momentum) space. The moentum space will be useful to you in determining certain optoelectronic properties.

Well, absolute zero means no objects and particles are moving. But gravity still independently acts on the particles and objects. That can only happen at some well equilibrated state.

You either 1. Integrate acceleration up to t=5 if acceleration is given as a function of t OR 2. Find the area under the curve within t=0 and t=5 inclusive

ds is an infinitesimal distance which u can chose in cartesian coordinates, cylindrical or spherical coordinates. U want to chose ds along the line which contains the flux or the current, ...

if you apply a temperature gradient it should generate a potential.

no relation. heat capacity is in J/kg or J/mol but heat capacitance is not a definition I've come across in Physics.
