In Newton's cannonball experiment, if the velocity is equal to the orbital velocity then the cannonball will stay in Orbit.
Newtons cannonball experiment stated that the distance that a cannonball will travel, before being drawn into the Earth by the forces of gravity, is dependent on the initial velocity.
Therefore, if the cannonball is launched at a velocity that matches the orbital velocity, then it will not be able to be drawn in by gravity due to the Earth moving away from the cannonball at the same speed at which the cannonball itself is falling.
This means that the cannonball will continue to fall without reaching the Earth, therefore staying in orbit, much like that of the moon or planets around the sun.

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.
The difference between the frequencies of the piano key and the tuning fork gives the frequency of the beats.
When the tuning fork is 405 Hz, and no beats are heard, then the piano key is also 405 Hz.
When the piano key is 405 Hz and the tuning fork is 402 Hz, then 405 - 402 = 3 beats are heard.
The piano key is 405 Hz.
