The most common states of awareness include conscious and unconscious. Wakefulness refers to a state of consciousness that is characterized by high levels of awareness and thought.

  • Fast, irregular, and low-amplitude electrical activity correspond to WAKEFULNESS.

  • An electroencephalogram is a diagnostic test that can be used to measure the brain's electrical activity during wakefulness and sleep.

  • Wakefulness is characterized by low-voltage (i.e., 5 to 10 microvolts) and high-frequency brain waves. These waves are known as beta and gamma waves.

  • Conversely, sleep is characterized by higher voltage and slow brain waves (i.e., synchronized pattern).

A sled of mass m is being pulled horizontally by a constant horizontal force of magnitude F. The coefficient of kinetic friction
lorasvet [3.4K]

Answer:

The average velocity of the sled is vavg = s/t.

Explanation:

Hi there!

The average velocity is calculated as the traveled distance over time:

vavg = Δx/Δt

Where:

vavg = average velocity.

Δx = traveled distance.

Δt = elapsed time.

We already know the traveled distance (s) and also know the time it takes the sled to travel that distance (t). Then, the average velocity can be calculated as follows:

vavg = s/t

Have a nice day!

The law of reflection is quite useful for mirrors and other flat, shiny surfaces. (This sort of reflection is called specular re
Sever21 [200]

Answer:

Explanation:

Suppose initially the plane was horizontal and light was reflected back at some angle θ from the normal .

Now the reflecting surface is twisted so that is becomes inclined at angle alpha .

The reflected light will be deviated from its original direction by angle

2 x alpha .

Similarly when the reflecting surface is further twisted so that it becomes inclined at angle beta then again the reflected beam will deviated by angle

2 x beta

Hence angle between these two reflected beam

= 2 beta - 2 alpha

= 2 ( β - α )

So, angular separation between the rays reflected from the two surfaces

= 2 ( β - α ) .

Suppose you exert 150 n on your refrigerator and push it across the kitchen floor at constant velocity. what friction force acts
Pachacha [2.7K]
Due that the velocity is constant that means that friction force is equal to the force exert by you, otherwise the refrigerator will accelerate or decelerate and in both cases velocity will not be constant.  
So then the friction force between refrigerator and floor is 150 Newtons.

How often is water added to the Earth system?
rosijanka [135]
<span>Water is never added to earth system. Water forever remains in the water cycle on earth, so it goes from the ground, to the air, to the rain, to the sea, and round and round continuously. This cycle means that there does not need to be new water added to the earth, because it recycles any water that already exists of its own accord.</span>
