    Finding mass of ice, using densities

    Homework Statement a polar bear weighing 1250 kg is on a slab of ice. The slab of ice is at water level. The density of the ice is 925 kg/m3 and the water is 1030 kg/m3. Find the mass of the slab of ice Homework Equations Density = Mass/Volume The Attempt at a Solution SInce the...

    Mesh/Nodal analysis with superposition, dependent source and diff frequencies

    I see what you meant by your fisrt comment now. The textbook I am learning from teaches that we "open circuit" the current sources and ignore them in any of the KCL/KVL equations, solve for the unknows and then do the same with voltage sources. Now that I have seen your solution it makes...

    Mesh/Nodal analysis with superposition, dependent source and diff frequencies

    Sorry that equation should be: V2/-5j + (V2-V1)/5 + (V2 - (2Vx+V1))/10j = 0 As I mentioned in my post, I am doing this using superposition so I open circuited the current source. I am trying to find Vx due to only the Voltage source first. Eventually I can say Vx(due to voltage soure)...

    Mesh/Nodal analysis with superposition, dependent source and diff frequencies

    Hi, I am preparing for my circuits final and I am having trouble with this question. Can someone guide me through it? I am trying to solve this using phasors. I know I will have to use superposition since the circuit contains sources with different frequencies. So first I start of...

    Engineering Simplifying Complex Resistor Circuits

    Homework Statement See attached image. Homework Equations The Attempt at a Solution I cannot find any resistors in parallel or series in the circuit. I am confused by the lone branch going from the 10kOhm resistor back to the other end of the same resistor. How do I deal with...

    Capacitor charged and disconnected then connected to capacitors

    Initially, a 15uF capacitor is charged by a 100V battery. Once charged, it is disconnected from the battery and connected to two uncharged capacitors(C_2 = 20uF, C_3 = 30uF) in parallel. What is the charge and potential difference on each capacitor. (The two capacitors mentioned above are in...
