Answer:
just-noticeable difference
Explanation:
Using principles of psychology and physics, a branch of experimental psychology called psychophysics has been created. This field is focused on the sensation, the sense and the perception of stimuli. Within this branch it has been called just-noticeable difference to the amount that must be changed of some stimulus so that this difference is noticeable, that is to say, the threshold at which the change is perceived.
For the horizontal component <u>we have:</u>
Vx = Vo * cos α
Replacing we have:
Vx = 24 * cos 45°
Resolving:
Vx = 24 * 0.525...
Vx = 12.607
The horizontal velocity is <u>12,607 m/s.</u>
Answer:
Sequence of layers to encounter while travelling from Earth to the surface of the sun are:
Option (A) - Corona
Option (C) - Chromosphere
Option (B) - Photosphere
Explanation:
- Corona- It represents the extreme outer region of the surface of the sun. It is normally not visible because of the light emitted from the sun. So it is difficult to be seen from the naked eye, but it can be seen during the time of total solar eclipse. The temperature in this region is about several million degrees.
- Chromosphere- It is a layer that lies between the Corona and the Photosphere. This layer has a thickness of about 2000 kilometers and the temperature in this layer ranges from about 6000°C to 20,000°C.
- Photosphere- This layer is the bright visible layer of the sun which is comprised of plasma and dark and cool sunspots, that forms on the sun due to the emerging of the magnetic field of the sun from its surface.
Thus, the correct sequences are mentioned above.
For any object to move at a constant velocity, the net force acting on the object must be ZERO.
