Determine the voltages V3 and V4, chown t

can someone help me with parts A-C and explain the concepts for the slope parts explain how exactly you are getting those numbers

could you help me please it's one question

I need helpo with this. I need step by step solutions for this and I cant figure it out.  Wire to be used in buildings and homes in the United States is standardized according to the AWGsystem (American Wire Gauge). Wires are assigned a gauge number according to their diameter.The scale ranges from gauge 0000 to gauge 36 in 39 steps. The equation for the wire gauge interms of the wire diameter in millimeters is as follows.Answer the following questions with your group.(a) What is the equation for the diameter in millimeters in terms of the wire gauge N?(b) You have two wires, one that has five times the diameter of the other. By how much do thewire gauges differ for the two wires? (Give your answer to the nearest integer.)

Please help with a, d, f, h. I don't know why my values are coming out incorrect even though the units are correct.

Consider the circuit shown by the figure below where all batteries are ideal batteries. Find the unknown currents and EMFs (answer parts A to E below). Round all your answers to whole numbers (i.e., no decimal figures). If you found any of the currents or EMFs to be negative, include the negative sign in your answer.A) e1= ? VB) Ic = ? Аc) Ia= ? A D)IF= ? A E)Ib= ?Adiagram below

please see attachment, thank you

Shown here is a simplified representation of an electrical power plant and a house, with the source of electricity shown as a battery, and the only electrical "load" in the house being a single light bulb: Power lines Power plant House Why would anyone use two wires to conduct electricity from a power plant to a house, as shown, when they could simply use one wire and a pair of ground connections, like this?
