One meter of shielded microphone cable weighs 751000 kilograms. What is the length of cable in the coil that weighs 5 12 kilograms?

To find the length of cable that weighs 5.12 kilograms, you can set up a proportion. Since 1 meter of cable weighs 751000 kilograms, you can calculate the length of cable that weighs 5.12 kilograms by cross-multiplying in the proportion (1 meter / 751000 kilograms) = (x meters / 5.12 kilograms). Solving for x, you get approximately 0.0068 meters.
