Denser materials have more tightly packed particles so the vibrations of the particles are transmitted faster, thus sound moves

faster through denser materials
True or False?

Answer:

True

Explanation:

Since sound is more easily transmitted between close molecules, it travels faster in the denser substance. Sound moves faster through denser air because the molecules are closer together in dense air and sound can be more easily passed on.

Damage to a brain area called the _____ would MOST likely interfere with learning a conditioned fear response to the sight of a
ELEN [110]

Answer:

The options

A)hippocampus

B)basal ganglia

C)hypothalamus

D)cerebellum

The CORRECT ANSWER IS D)

D)cerebellum

Explanation:

Apart from the coordinating process, the cerebellum is involved in motor learning, emotional behavior, and fear memory.

Fear learning is widely shown in the variation of autonomic and somatic responses, as in heart rate and freezing, promoted by a neutral stimulus which could have been formally grouped with a painful one.

Variation or changes of the vermis influences these responses, and its reversible inactivation in the period of consolidation which is seen to impair fear memory.

The neural correlate of cerebellar activities in fear consolidation is shown by a behaviorally promoted long-term rise of synaptic effectiveness and efficiencies among parallel fibers and a Purkinje cell.

Likely synaptic variations after fear conditioning are well fully observed in the amygdala and hippocampus, suggesting an interplay among emotional circumstances of scenario and the different variations in neural process.

Furthermore, in hotfoot mice, that shows a basic lack of parallel fiber to Purkinje cell synapse, short- and long-term fear memories are influenced.

All these data gives a foundational background on the concept that the cerebellum is majorly involved in fear learning.

The functional interplay of the vermis with hypothalamus, amygdala, and hippocampus do infer to a more complex activities of the cerebellum as a form of an united network that basically influences emotional behavior.

What happens when light waves passes through glasses
Andreyy89
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly. Since the light speed changes at the interface, the wavelength of the light must change, too. The wavelength decreases as the light enters the medium and the light wave changes direction. We illustrate this concept in Figure 3 by representing incident light as parallel waves with a uniform wavelength . As the light enters the glass the wavelength changes to a smaller value '. Wave "a" passes the air/glass interface and slows down before b, c, or d arrive at the interface. The break in the wave-front intersecting the interface occurs when waves "a" and "b" have entered the glass, slowed down and changed direction. At the next wave-front in the glass, all four waves are now traveling with the same velocity and wavelength
