Question

1. what kind of information do black hole detectors not provide? photon intensity precise timing specific positional information power of a black hole

Explanation:

Black - hole detectors can measure photon intensity, provide precise timing, and give some positional information related to the signals they detect. However, the "power" of a black hole is a complex and not - directly - measurable quantity for these detectors. They don't have the means to directly determine the power output of a black hole in a straightforward way.

Answer:

D. power of a black hole
