Answer:
(a). I' = 17.24 A
(b).The current in second wire is in opposite direction compare to first wire.
Explanation:
Given data
r = 0.038 m
4.9 ×
I = 0.54 A
(a). The current in the second wire is calculated as
Put all the values in above formula we get
I' = 17.24 A
(b). The current in the two wires is in opposite directions because the wires repeal each other. therefore the current in second wire is in opposite direction compare to first wire.
Complete Question
An isolated charged soap bubble of radius R0 = 7.45 cm is at a potential of V0=307.0 volts. V0=307.0 volts. If the bubble shrinks to a radius that is 19.0%19.0% of the initial radius, by how much does its electrostatic potential energy ????U change? Assume that the charge on the bubble is spread evenly over the surface, and that the total charge on the bubble r
Answer:
The difference is
Explanation:
From the question we are told that
The radius of the soap bubble is
The potential of the soap bubble is
The new radius of the soap bubble is
The initial electric potential is mathematically represented as
The final electric potential is mathematically represented as
