Answer:
To find the diameter of the wire, when the following are given:
Resistivity of the material (Rho), Current flowing in the conductor, I, Potential difference across the conductor ends, V, and length of the wire/conductor, L.
Using the ohm's law,
Resistance R = (rho*L)/A
R = V/I.
Crossectional area of the wire A = π*square of radius
Radius = sqrt(A/π)
Diameter = Radius/2 = [sqrt(A/π)]
Making A the subject of the formular
A = (rho* L* I)V.
From the result of A, Diameter can be determined using
Diameter = [sqrt(A/π)]/2. π is a constant with the value 22/7
Explanation:
Error and uncertainty can be measured varying the value of the parameters used and calculating different values of the diameters. Compare the values using standard deviation
Answer:
The answer is C, a thermometer reads 0.1 degree higher than it should.
-- Conserve. Don't use more than we need. There isn't any more of it.
-- Conserve. Don't pollute what we have. There isn't any more of it.
Of course, what we REALLY need to do is <u><em>convince</em></u> great numbers of people to go along with these suggestions. Otherwise it won't work.
