Charge conservation charge in a region and the flow of charge into and out of that region, given by a continuity equation between charge density formula_1 and current density formula_2. This does not mean that individual positive and negative charges cannot be created or destroyed. Electric charge is carried by subatomic particles such as electrons and protons. Charged particles can be created and destroyed in elementary particle reactions. In particle physics, charge conservation means that in reactions that create charged particles, equal numbers of positive and negative particles are always created, keeping the net amount of charge unchanged. Similarly, when particles are
Passenger Movement Charge negative impact of the pilots' dispute of 1989. The departure tax was raised again in 1994 to A$25 to offset the additional cost of tourism promotion expenditure, specifically an additional A$80 million allocated to the development of new tourism products. Since its name change to passenger movement charge in 1995, the rate of the PMC has changed on several occasions. In most cases the Australian federal government has given a rationale for rate increases. Australia's departure tax is one of the highest in the world. Few jurisdictions levy taxes on departing international passengers, although some charge airport fees to cover
