It's an 8 ohm resistor connected to the 12V battery. Sorry I have no internet connection and am running off a hotspot on my phone, hence why my question is so rushed.

Circuit is a line. On the diagram the Earth comes off one of the corners of the circuit e.g 12v--12ohm--7v| | |-----------4ohm| | E And the polarity is set out for the 12v -+-+ & for the 7v +-+-

Homework Statement The series circuit is connected as follows: A 12V Battery -> 8ohm resistor -> 7V Battery -> 4ohm Resistor -> Earth. The problem states that if a voltmeter was connected from a point between the 12V battery & the 8ohm Resistor and connected to a point above the Earth then...

Got it. Thanks for the help :)

So I'm assuming you can solve both equations simultaneously as they both equal one another?

Chestermiller do you not think i have spent hours upon hours researching this. My textbook has no similar question when adding a variable like that so I have not been taught, and i cannot find it anywhere on google which is why i signed up on this forum. If you can find something teaching it...

Yes sorry assuming the iron mass is also at 45 degrees initial temperature. I haven't found any similar questions so I'm very confused. If i was to add in the latent heat wouldn't i then need the quantity of heat which i haven't been given?? Q= mc(t2-t1) + mLf + mc(t2-t1) and how would...

Homework Statement A 30.0g block of ice at 0.00°C is dropped into 500.0g of water at 45.0°C. If the process was carried out in an iron container with a mass of 150g what would the final temperature be? Homework Equations Q=mc(T2-T1) Heat Lost = Heat Gained Specific Heat of Water: 4200 Specific...
