D: the linear displacement
举一反三
- The resistance of a light sensor in bright light is ________ that in the dark
- The resistance value is infinite, the current passing through the resistance is always zero, and the voltage depends on the external circuit, then it is called as the short circuit state.
- Can there be a temperature at which °C and °F have the same value? Can there be more than one such temperature?
- 中国大学MOOC: Plants can detect what about light?
- When a photodetector is used to detect the intensity of light, it should be A: reverse-biased B: forward-biased C: zero-biased D: none of the above
