Final answer:
In an accuracy check for comparing two VOR's, one calculates the percent error by comparing the measured value of a parameter, such as the speed of light, to its accepted value. For astronomical observations, analyzing measurements from an observatory, such as relative position and proper motion, can reveal if two stars are gravitationally bound as a visual binary.
Step-by-step explanation:
The accuracy check when comparing two VOR's involves analyzing the consistency and precision of navigational signals. As students, you may apply this concept in physics experiments, for example, when measuring the speed of light. To assess this, you could use the percent error formula, which compares your measured value to the accepted value of the speed of light. The percent error is calculated by subtracting the accepted value from the measured value, dividing the result by the accepted value, and then multiplying by 100 to get a percentage.
If you were to determine whether two stars are a visual binary, you would measure and analyze multiple parameters at an observatory. Key measurements could include their relative position changes over time, proper motion, parallax to ascertain distance, and spectral analysis to understand their composition and dynamics. Comparing these measurements to known binaries would allow you to conclude if the stars are gravitationally bound and orbiting each other.
