How do vacuum fluctuations contribute to the Casimir effect observed between two conductive plates?
They cause a difference in vacuum energy density between the plates and outside, resulting in an attractive force.
They generate real particles that push the plates apart due to radiation pressure.
They create a magnetic field that magnetizes the plates, causing attraction.

How do vacuum fluctuations demonstrate the principles of the Heisenberg uncertainty principle in quantum physics?
They show that energy can temporarily fluctuate in a vacuum due to the uncertainty in energy and time, allowing particle-antiparticle pairs to spontaneously appear and disappear.
They prove that energy in a vacuum is always zero and never changes.
They indicate that particles in a vacuum are permanently created and do not annihilate.

How do vacuum fluctuations demonstrate the principles of the Heisenberg uncertainty principle in quantum physics?
They prove that energy in a vacuum is always zero and unchanging over time.
They indicate that particles in a vacuum are permanently created and destroyed without any time constraints.
They show that energy and time cannot both be precisely determined, allowing temporary energy changes that create virtual particles.
