It seems that you have missed the necessary options for us to answer this question, but anyway here are the answers. The interaction between two optical and perceptual phenomena makes moving pictures possible. the persistence of vision provides the illusion of SUCCESSION <span>while the phi phenomenon provides the illusion of MOVEMENT.

Answer:
Option D) -0.0707
Explanation:
We are given the following in the question:
Population mean, μ = 45 mp
Sample mean, = 44.9
Sample size, n = 50
Sample standard deviation, s = 10
Formula:
Putting all the values, we have
Thus, the test statistic is
Option D) -0.0707
Answer:
hertz (Hz)
The number of periods or cycles per second is called frequency. The SI unit for frequency is the hertz (Hz).
Answer:
E(1m) = 4*E(2m)
Explanation:
By definition, an electric field is the electric force per unit charge, produced by a given charge distribution.
For a point charge, it is the electric force produced by the charge, over a positive test charge located at a distance d from the charge.
So, the E at a point 2 m away from the charge q, can be expressed as follows:
At a point 1 m from the charge, the value of E is given by the following equation:
As it can be easily seen, the magnitude of the electric field at 1 m from the charge creating it, is 4 times larger than the one at 2 m.
This is due to the electrostatic force obeys an inverse-square law, consequence of our universe be three-dimensional.
