Which of the following pairs of variables does not have units of work?Group of answer choicesFdmvPVqE

The pair of variables that does not have units of work is qE.

Here's why:

1. Fd: This represents Force times distance, which is the definition of work in physics. So, it has units of work.

2. mv: This represents mass times velocity, which is the definition of momentum, not work. So, it does not have units of work.

3. PV: This represents Pressure times Volume, which is the definition of work in thermodynamics. So, it has units of work.

4. qE: This represents charge times electric field. This is not a definition of work. So, it does not have units of work.

Therefore, the pairs mv and qE do not have units of work.
