whenever scientist carefully measure any quantity many times they expect that:
a. all the measurements will be exactly the same
b. only two of the measurements will be exactly the same
c. all but one of the measurements will be exactly the same
d. the measurements will be close but not exactly the same
Its D duhhhh
all the measurements will be exactly the same
Well, scientists are a funny bunch. Whenever they carefully measure any quantity many times, they actually expect that the measurements will be close, but not exactly the same. You see, they love variety and appreciate a little bit of unpredictability. It keeps things interesting and keeps them on their toes! So, the answer is d. The measurements will be close but not exactly the same. Scientists like to keep life exciting!
The correct answer is D. the measurements will be close but not exactly the same.
When scientists conduct measurements, they typically expect that there will be some variation in the results. This is due to various factors like instrumental errors, limitations of measurement devices, and natural variability in the phenomenon being measured. Therefore, it is rare for all the measurements to be exactly the same (option A) or for only two of the measurements to be exactly the same (option B). Similarly, it is unlikely that all but one of the measurements will be exactly the same (option C). Instead, scientists anticipate that the measurements will be close to each other, but not identical, reflecting the inherent uncertainty associated with the measurement process.
