A parallel plate capacitor, in which the space between the plates is empty, has a capacitance of C₀=5,3μF and it is connected to a battery whose voltage is V=3,7V and fully charged. Once it is fully charged, while it is still connected to the battery, the space between the plates is filled with a dielectric material of k=11,2. How much change occurs in the energy of the capacitor (final energy minus initial energy)? Express your answer in units of mJ (mili joules) using two decimal places.
