The equatorial radius of the earth is approximately 3960 mL. Suppose that a wire is wrapped tightly around the earth at the equator. Approximately how much must this wire be lengthened if it is to be strung all the way around the earth on poles 10 ft above ground?© BrainMass Inc. brainmass.com October 9, 2019, 10:31 pm ad1c9bdddf
10 feet = 10 x 0.00019 miles = 0.0019 miles
Length of the wire required when it is tightly ...
This solution contains step-by-step calculations to determine how long a wire must be to be strung all the way around the earth poles raised above the ground.
