question 81

Multiple Choice

Maxwell's great contribution to electromagnetic theory was his hypothesis that:

• A) work is required to move a magnetic pole through a closed path surrounding a current
• B) a time-varying electric flux acts as a current for purposes of producing a magnetic field
• C) the speed of light could be determined from simple electrostatic and magnetostatic experiments (finding the values of \(\mu\)₀ and )
• D) the magnetic force on a moving charge particle is perpendicular to both
• E) magnetism could be explained in terms of circulating currents in atoms

Performance Evaluation

The process of assessing and reviewing an employee's or organization's work performance and outcomes against established standards or objectives.

Labor Efficiency Variance

The difference between the actual labor-hours taken to complete a task and the standard hours allowed for the actual output, multiplied by the standard hourly labor rate.

Standard

A benchmark or guideline used to measure or set the quality, quantity, or value of products or processes.

Variable Overhead Efficiency Variance

The difference between the actual level of activity (direct labor-hours, machine-hours, or some other base) and the standard activity allowed, multiplied by the variable part of the predetermined overhead rate.
