Answer:

Twenty four

Explanation:

An experiment can be explained as the testing of a hypothesis. In the experiment, an independent variable can be manipulated and the dependent variable could not be manipulated. The dependent variable could be measured and the extraneous variable could be controlled. The advantage of the experiment is that it is objective so the viewpoint of a researcher does not affect an experiment. So the date becomes more valid and reliable and not biased.  

<u>There are conducted three types of experiment : </u>

  • Lab experiment
  • Field experiment
  • Natural experiment

notka56 [123]

With regard to rotating limbs to project objects, a relationship exists between the <u>velocity</u> of the rotating arm and the<u> </u><u>velocity</u> of the projected object.

In easy words, velocity is the rate at which something moves in a specific route. For instance, the speed of a car touring north on a highway, or the speed a rocket travels after launching.

Speed (v) is a vector quantity that measures displacement (or change in function, Δs) over the exchange in time (Δt), represented by means of the equation v = Δs/Δt. Velocity (or price, r) is a scalar quantity that measures the space traveled (d) over the trade in time (Δt), represented by using the equation r = d/Δt.

The pace is the directional pace of an item in motion as an indication of its price of alternate in function as observed from a selected frame of reference and as measured by way of a particular preferred time.
