What is the wave characteristic of stage 1 sleep

Physics
1 answer:
spin [16.1K]4 years ago
5 0
We all think that sleep has a uniform state of being. This is a wrong connotation but instead, the truth is sleep is composed of several different stages. This can be differentiated from one another by the patterns of brain wave activity that occur during each stage. In the 1st stage of the non-rapid eye movement or NREM, this is when the transitional phase occurs between wakefulness and sleep. This is the period when we drift off to sleep. The heartbeat as well as the respiration rates in the body slow down during this period. Furthermore, in stage 1 there is marked decrease in both overall muscle tension and core body temperature. Stage 1 wave activity s directly associated with the alpha and theta waves. It isa said that it is really easy to wake a person who is still at stage 1 and are not even convinced that he or she has been asleep during this stage.

The normal force equals the magnitude of the gravitational force as a roller coaster car crosses the top of a 40-m-diameter loop
iogann1982 [59]

Answer:

Explanation:

Given

Diameter d=40\ m

radius r=20\ m

From diagram, at top point

If Normal force is equal to Gravitational force

N=mg

where N=normal reaction

m=mass of car

Normal reaction will provide centripetal force

N=\frac{mv^2}{r}

thus

\frac{mv^2}{r}=mg

v=\sqrt{2gr}

v=\sqrt{2\times 9.8\times 20}

v=19.79\ m/s

Describe a ball's motion as it rolls up a slanted
emmasim [6.3K]

The ball will decelerate as it moves upwards.

The magnitude of the ball's acceleration is 0.3 m/s² and it directed backwards.

The given parameters;

  • initial velocity of the ball, u = 1.25 m/s
  • time of motion of the ball, t = 4.22 s

As the ball rolls up the inclined plane, the velocity decreases and eventually becomes zero when the ball reaches the highest point of the plane.

Thus, the ball decelerate as it moves upwards.

The acceleration of the ball is calculate as;

a = \frac{v_f -v_0}{t} \\\\

<em>at the highest point on the incline plane, the final velocity </em>v_f<em> is zero</em>

a = \frac{0-1.25}{4.22} \\\\a = -0.3 \ m/s^2

Thus, the magnitude of the ball's acceleration is 0.3 m/s² and it directed backwards.
