Question

dimensional analysis
how should you arrange conversion factors in dimensional analysis?
the units of the given should cross multiply with the conversion factor.
the units of the given should cancel straight across with the conversion factor.
the units of the given should add straight across and then divide.
the units of the given should cancel top - to - bottom with the conversion factor.

Explanation:

In dimensional analysis, the goal is to cancel out unwanted units. This is achieved by arranging conversion - factors such that the units of the given quantity cancel straight across with the units in the conversion factor. For example, if you have a length in inches and want to convert it to centimeters, and you know the conversion factor is 2.54 cm per 1 inch, you set up the calculation so that the "inches" unit in the given quantity and the "inches" unit in the conversion factor cancel each other out.

Answer:

The units of the given should cancel straight across with the conversion factor.
