Answer:

There are four different stages of sleep.

Stage 1 NREM

Explanation:

<em>The process of firmly falling asleep has four stages through which a person goes.</em>

<em>It goes from being awake over light sleep and falling firmly into sleeping.</em>

(STAGE 1)

This is a stage in which there are non-rapid movements of the eyes. In other words, it is a process of dreamless sleep. You enter this stage the moment you decide to sleep and shut your eyes. After several minutes, your body is in fact in the sleeping mode, but not entirely. This means that you can easily be woken up without being aware that you have slept.

Features:

  1. <em>You can easily awake</em>
  2. <em>Your may roll and they may be a little open</em>
  3. <em>The blood pressure and the temperature of the brain start to decrease </em>
  4. <em>You experience the natural human reflexes that the brain sends to assure that the place of your sleep is in a safe environment. By sending twitches to your muscles, your brain may awake your body for several seconds which comes in handy if you are tired and close to sleep on work or some dangerous place like a cliff for example.</em>
  5. <em>Your breading starts to slow down alongside with your pressure and temperature, and your heartbeats slow down.</em>

It goes from being awake over light sleep and falling firmly into sleeping.

(STAGE 1)

After several minutes, your body is in fact in the sleeping mode, but not entirely. This means that you can easily be woken up without being aware that you have slept.

Features:

Your may roll and they may be a little open

The blood pressure and the temperature of the brain start to decrease

You experience the natural human reflexes that the brain sends to assure that the place of your sleep is in a safe environment. By sending twitches to your muscles, your brain may awake your body for several seconds which comes in handy if you are tired and close to sleep on work or some dangerous place like a cliff for example.

Your breading starts to slow down alongside with your pressure and temperature, and your heartbeats slow down.

If a lens has a power of -14.50, what is the focal length in mm?
ra1l [238]

Answer:

Focal length of the lens, f = - 68 mm

Explanation:

Given that,

Power of a lens, P = -14.50 D

We need to find the focal length of the lens. We know that the focal length and the power of lens has inverse relationship. Mathematically, it is given by :

f=\dfrac{1}{P}

f is the focal length of the lens

f=\dfrac{1}{-14.50}

f = -0.068 m

or

f = -68 mm

So, the focal length of the lens is (-68 mm). Hence, this is the required solution.

What is the efficacy of a 60.0 W incandescent lightbulb that produces 830 lumens?
Alex17521 [72]

η = 13.8 lm/W. The luminous efficacy of a incandescent lightbulb that produces 830 lumens and consumed a power of 60 W is 13.8 lm/W.

The luminous efficacy of a light source is the relationship between the luminous flux (in lumens) emitted by a light source and the power (in watts). The luminous efficacy of a light source or luminous efficiency measures the part of electrical energy that is used to illuminate and is obtained by dividing the luminous flux emitted by the electrical power consumed. Luminous efficiency is expressed in lumens per watt (lm / W). It is given by the relation:

η = F / P.  Where F is the luminous flux, and P is the power consumed by the light source.

The efficacy of a 60.0 W incandescent lightbulb that produces 830 lm is:

η = 830 lm / 60 W

η = 13.8 lm/W

help me.. a car moves for half of its time at 80km/h nd for rest of time at 40km/h.total distance coverd is 60km..wat is averge
nalin [4]
Let's use ' t ' to represent half of the time, in hours.

The distance traveled in the first half of the time is  (80 t) km.

The distance traveled in the last half of the time is  (40 t) km.

The total distance covered is    (80t + 40t) = (120t)  km.

You said that the total distance covered was  60 km,
so ...
                             120 t  =  60 km

Divide each side by  120 :      t (half of the time) = 0.5 hour

Average speed = (total distance covered) / (time to cover the distance)

                           =      (60 km)  /  (1 hour)

                           =            60 km/hr .
