As Shown in the Figure,a Wire and a 10-Ω Resistor

question 26

Multiple Choice

As shown in the figure,a wire and a 10-Ω resistor are used to form a circuit in the shape of a square,20 cm by 20 cm.A uniform but nonsteady magnetic field is directed into the plane of the circuit.The magnitude of the magnetic field is decreased from 1.50 T to 0.50 T in a time interval of 63 ms.The average induced current and its direction through the resistor,in this time interval,are closest to

• A)63 mA,from b to a.
• B)38 mA,from b to a.
• C)63 mA,from a to b.
• D)38 mA,from a to b.
• E)95 mA,from a to b.

Definitions:

Halo Error

A cognitive bias in performance appraisals where one trait of an individual influences the evaluator's view of other traits.

Recency Error

The tendency to evaluate someone's performance based on their most recent behavior rather than on a longer period of observational time.

Leniency Error

A bias in performance evaluations where the reviewer rates an individual more favorably than is warranted by his or her performance.
