    Capacitors in series or in parallel? - calculating CR

    So in the first example, when I move the switch to B, the capacitors are in series. In the second example, however, the total capacitance is in parallel... so what is the difference?

    Capacitors in series or in parallel? - calculating CR

    so in the second problem, they are in parallel but in the first one they are in series?

    Capacitors in series or in parallel? - calculating CR

    how is that then different from the second question I showed where S1 was open and S2 was closed?

    Capacitors in series or in parallel? - calculating CR

    Homework Statement I have the circuit above. When I have the switch at A, the capacitor C1 is charging at 100μF is at 10V. I then discharge the capacitor by connecting the switch to B. I was asked to calculate the time constant. I thought the capacitors were in parallel but according to...

    Physics Archimedes Principle Distance an object sinks

    The density of the object is 525 kgm-3 and the density of the water is 1000 kgm-3 so it must be sink 52.5% into the water?

    Physics Archimedes Principle Distance an object sinks

    Homework Statement A block of wood measures 2.2m by 2.5m with depth 3.6m with weight 102KN. When placed in water, how far will it sink? g = 9.81 ms-2 density of water = 1000kg m-3 Homework EquationsThe Attempt at a Solution Volume = 2.2(2.5)(3.6) = 19.8m3 Mass = 102000 / 9.81 = 10398 kg...

    Concrete Block Incline acceleration question

    Homework Statement A concrete block of mass 25kg is placed on a smooth slope that makes an angle of 30 degrees with the horizontal. Ignoring the effects of air resistance, calculate a) the acceleration of the block as it slides down (g = 9.81 ms-2) b) the distance the block moves in 3 seconds...
