Chapter 2, Problem 70E

The Heisenberg uncertainty principle can be expressed in the form

$\Delta E\cdot \Delta t\ge \frac{h}{4\pi }$

where E represents energy and t represents time. Show that the units for this form are the same as the units for the form used in this chapter:

$\Delta x\cdot \Delta \left(mv\right)\ge \frac{h}{4\pi }$
