Answer the following question given this paragraph: 22.6 The Hall Effect We have seen effects of a magnetic field on free-moving charges. The magnetic field also affects charges moving in a conductor. One result is the Hall effect, which has important implications and applications. Figure 22.27 shows what happens to charges moving through a conductor in a magnetic field. The field is perpendicular to the electron drift velocity and to the width of the conductor. Note that conventional current is to the right in both parts of the figure. In part (a), electrons carry the current and move to the left. In part (b), positive charges carry the current and move to the right. Moving electrons feel a magnetic force toward one side of the conductor, leaving a net positive charge on the other side. This separation of charge creates a voltage , known as the Hall emf, across the conductor. The creation of a voltage across a current-carrying conductor by a magnetic field is known as the Hall effect, after Edwin Hall, the American physicist who discovered it in 1879. Q: The creation of a voltage across a current-carrying conductor by a magnetic field is known as what? A:
OPTIONS:
- off effect
- newton effect
- show effect
- hall effect
hall effect

Answer the following question given this paragraph: The rate of decay of carbon-14 is stable over time. Q: The rate of decay of carbon-14 does what over time? A:

- increases
- decreases
- remains stable

input with options: Answer the following question given this paragraph: Plants may not be able to move to another location, but they are able to change how they grow in response to their environment. Growth toward or away from a stimulus is known as a tropism ( Table below ). Auxins, a class of plant hormones, allow plants to curve in specific directions as they grow. The auxin moves to one side of the stem, where it starts a chain of events that cause rapid cell growth on just that one side of the stem. With one side of the stem growing faster than the other, the plant begins to bend. Q: What plant hormone allows plants to curve in a specific direction? A:
OPTIONS:
- peptides
- pheremone
- apoptosis
- auxin
output:
auxin
