Exponential notation to represent numeric


Find the Voltage drop across an 53.2 m long copper wire with diameter of 1.15 mm and with 43.7 miliAmps of current running through it. (The resistivity of copper at room temperature is 1.68×10-8 Ohm×meter). Express the answer to three significant figures.

Tip: you can use scientific/exponential notation to represent numeric values. Eg., -0.0001 can be written as 1.0e-4 or as 1.0E-4. Spaces are not allowed.
