Is there anyway to get this back and is the solution specific to the make of laptop?
Thanks for the help
Q5. The light in a car park is suplied via a cable 85m long. The area of the cable is 4mm². Calculate the resistance of the cable if the resistivity is 1.67x 10 to the power of -8 ohms.
R = p x L/A
p x 85000/4 = 0.000354875
Q4 A coil is made up of 12000 turns of copper wire. the lenght per turn is 120mm, and the area is 0.275mm². Calculate the resistanceof the coil if the resistivity is 1.67 x 10 to the power of -8.
1.67x10^-8 x 12000x120mm / 0.275 = 0.08744...

Yeah bt probably will upgrade soon enough, quite a few of its lines can support it. The whole telecoms industry has set a target to dramatically improve internet connections.
This may involve digging up roads and laying fibre optics.
However, new research has gone into houses recieving their...
