A wire is made of two equal-diameter segments with conductivities σ1 and σ2. When a current passes through the wire, a thin layer of charge appears at the boundary between the segments, as shown below. Material 1 is iron and material 2 is copper. Both wires are 1.0 mm in diameter and 25 cm long. The current is 2.5 A. What is the voltage across the iron wire? What is the voltage across the copper wire? How much charge accumulates...

A weather forecaster predicts that the rainfall in November in a local area will be between two and eight inches but has no idea where within the interval the actual amount will be. In other words, all amounts within that interval are equally likely. (b) What would be a reasonable probability distribution to use to model the rainfall--assuming that the likelihood of rain over the range of possible amounts is the same?   (c) X ~  (  ,  ) (d) Write the formula for...

ELABORATE EXPLANATIONS PLEASEE 2) Consider babies born in the "normal" range of 37–43 weeks gestational age. A paper suggests that a normal distribution with mean μ = 3500 grams and standard deviation σ = 610 grams is a reasonable model for the probability distribution of the continuous numerical variable x = birth weight of a randomly selected full-term baby. a) What is the probability that the birth weight of a randomly selected fullterm baby exceeds 4000 g? b) What is...
If two wires carry current next to each other, they will exert a force on each...
If two wires carry current next to each other, they will exert a force on each other. The force is caused by magnetic fields. One current creates a magnetic field, and this field exerts a force on the other current. The magnitude of the field created by a long, straight current-carrying wire is given by Equation 1 below; B= (μ0i)/(2πr) where i is the current and r is the distance from the wire. The magnitude of the force exerted on...
