The question presents an equation an informs that there is a measurement conversion being made. We need to correctly calculate the value given (-8.4 x 10^4 N/cm) in the new unit (N/mm)
The problem presents the following conversion:
We can see this as 1/cm being transformed into 1/mm.
To do this calculation, we need to keep in mind the following information:
1 cm = 10 mm
Thus, we can write:
Now, let's bring the value given to the equation above:
Therefore, to make the conversion required, we need to divided the value by ten:
Therefore, the final answer should be -8.4 x 10^3 N/mm.
