Math Problem Statement
Give the answer as a number and in the requested units, rounded to two significant figures. If needed, use a dot / period as a decimal separator.
You were so inspired by the electronics course that you have decided to build your own lab in your basement. You have a coil which has a mass of 0.6000000000000001 kg. With a Vernier caliper you measure that the diameter of the wire is 0.1 mm. From a data book you check that the density of copper is 8900 kg/m 3 . Calculate the length of the wire so you can be sure it is long enough for the wiring. How long is the wire (m)?
