Final answer:
The current of negative charge related to water flow in a garden hose with a given volume flow rate cannot be determined without additional data on ion concentrations or applied electric fields. In a neutrally charged water flow, the electrical current would be zero.
Step-by-step explanation:
The question concerns the current of negative charge associated with the flow of water through a garden hose, with a given volume flow rate of 450 cm3/s. The current of negative charge can be calculated using the charge of an electron and the number of electrons that would be associated with that flow rate if the water were charged. However, pure water is electrically neutral, and the flow of water itself does not constitute an electrical current. Therefore, without additional information regarding ion concentrations or applied electric fields, we cannot directly calculate a current for negative charges in the context of water flow alone. If the water had a net charge, we would need the concentration of excess electrons or ions per volume to correctly determine the current. Typically, in a general physics context, if we are asked to calculate the flow of electrical current associated with a given flow rate of water, and not considering any dissolved ions or impurities that could carry a charge, the net electrical current would be zero.
