A student is given three wires that are made from different materials, but each wire has the same physical dimensions. For a given experiment, both ends of one wire are connected to a constant voltage power supply so that a closed circuit is established. The student has access to an ammeter and a voltmeter to make measurements for each wire. Which of the following types of data need to be collected to rank the wires in terms of their resistivity. Justify your selection. Use the ammeter to measure the current that flows through each wire, because a larger current that flows through the wire corresponds to a larger resistivity. Use the ammeter to measure the current that flows through each wire, because a larger current that flows through the wire corresponds to a smaller resistivity. Use the voltmeter to measure the potential difference across the wire, because a larger potential difference corresponds to a larger resistivity. Use the voltmeter to measure the potential difference across the wire, because a larger potential difference corresponds to a larger resistivity.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
