Ticker Tape analysis is a common way of analyzing the motion of the objects to perform in the physics laboratory. A long tape is attached to a moving object and threaded through a device that places a tick upon the tape at regular intervals of time. This ticker tape can also determine if the object is fast or slow. It can also reveal if the object is moving with a constant velocity or accelerating. The changing velocity and acceleration represented by the changing distance between dots in the ticker tape. And also the constant velocity and therefore no acceleration represent the constant distance between dots.
Answer:
Speed of the light in water= 225,000 km/s
Explanation:
At the speed with which light propagates through a homogeneous and transparent medium, it is a constant characteristic of that medium, and therefore, it changes from one medium to another.
Due to its enormous magnitude, the measurement of the speed of light has required the invention of ingenious procedures that will overcome the inconvenience of short land distances in relation to such extraordinary speed.
Astronomical methods and terrestrial methods have been giving ever closer results. At present, the value c = 299,792,458 km / s is accepted for the speed of light in a vacuum. In any transparent material medium the light propagates with a speed that is always lower than c. Thus, for example, in water it does so at around 75% of the speed of light in a vacuum: about 225,000 km / s.
Answer:
Research bias or Experimenter bias
Explanation:
Research bias or Experimenter bias is the phenomena that results when the researcher's preferences or hopes about the result influences the obtained outcomes.
This can also be explained as a result of the unconscious and subjective effect of the researcher's hopes on the data used in an experiment or the participants of the experiment or the outcome of the related experiment.
This can be avoided by the researcher by paying attention to the records made by the participants of the experiment and not based the outcome of the experiment on the basis of the his thinking.
Increase in speed or rate
