The total resistance is R = voltage / current
This resistance R = (L/A)r where:
r is the resistivity
L is the length of the conductor
A is the cross-sectional area of the conductor.
thus r = RA/L
You are given L; you can compute R from the voltage and current you are given; and the cross-sectional area of a round wire is (pi)(radius^2) or (pi/4)(diameter^2)
<span>An isothermal process is a change of a system, in which the temperature remains constant: ΔT = 0.</span>
Since you provide no options, here are some role of the foresters :
- they develop sustainable forest practice
- They asses timber Quality
- They make sure that all harvesting activities followed the law's regulation
- They plan and supervise forestry project
your answer might be the one that isn't included above
