The Figure Shows a Uniform Magnetic Field That Is Normal $\pi$

question 21

Multiple Choice

The figure shows a uniform magnetic field that is normal to the plane of the conducting loop of resistance R. Note: the area of the non-circular portion of the circuit is negligible compared to that of the loop.
-Suppose that the radius of the loop is 0.500 m. At what rate must B change with time if the emf induced in the loop is $\pi$ volts?

• A)12.0 T/s
• B)18.8 T/s
• C)24.0 T/s
• D)37.7 T/s
• E)49.2 T/s

Variances

Discrepancies between planned financial outcomes and the actual results, used in budgeting and accounting to analyze and control costs.

Quantity Variance

A variance that is computed by taking the difference between the actual quantity of the input used and the amount of the input that should have been used for the actual level of output and multiplying the result by the standard price of the input.

Standard Quantity

This refers to the predefined amount of materials or labor deemed necessary to produce a single unit of a product under normal operations.

Actual Quantity

The real number of units used or produced, as opposed to planned or estimated quantities.
