Explanation:
all I know is every number that have a bar on is equal to one
Answer: D) All of the above
Explanation:
Burn rate can be affected by all of the above reasons as, variation in chamber pressure because the pressure are dependence on the burn rate and temperature variation in initial gain can affect the rate of the chemical reactions and initial gain in the temperature increased the burning rate. As, gas flow velocity also influenced to increasing the burn rate as it flowing parallel to the surface burning. Burn rate is also known as erosive burning because of the variation in flow velocity and chamber pressure.
The statement "Visual perception is a mental process that is non selective" is false, it is a psychic function that allows the organism to capture, elaborate and interpret selective information that comes from the environment.
<h2>What is visual perception?</h2>
Visual perception is that inner sensation of apparent knowledge, resulting from a specific stimulus or light impression recorded by the eyes.
<h3>Characteristics of visual perception</h3>
- It incorporates the sensory stimuli received from objects, situations or events and converts them into a meaningful interpretation experience.
- It is an active process of the brain through which an external reality is created by transforming the light information captured by the eye.
Therefore, we can conclude that visual perception is the interpretation made by the brain of the different organisms of the stimuli received through the senses.
