Time taken by the body to move through a distance of 12 m is 2 s

Explanation:

using the equation for force

F= m a

m= mass= 1 kg

F= force= 6 N

a= acceleration=

6= 1 a

a= 6 m/s²

Now using the kinematic equation,

d= Vt + \frac{1}{2} at^2

d= distance= 12 m

V= initial velocity=0 as the object is at rest initially

12= 0(t)+ 1/2 (6) t²

t²=4

t= 2 s

A student weighing 700 N climbs at constant speed to the top of an 8 m vertical rope in 10 s. The average power expended by the
Goshia [24]

To solve this problem we will use the concepts related to power, defined as the amount of energy applied over a period of time.

The energy in this case is the accumulated in the form of potential energy, over a period of time. Thus we will have that the mathematical expression of the power can be expressed as

P = \frac{E}{t}

Here,

E = Energy

t = time

As the energy is equal to the potential Energy we have tat

P = \frac{mgh}{t}

The weight (mg) of the man is 700N, the height (h) is 8m and the time is 10s, then:

P = \frac{700*8}{10}

P = 560W

Therefore the correct answer is A.

Light of wavelength 500nm shines on a pair of slits. This produces an interference pattern on a screen 2.00m behind the slits. M
grandymaker [24]

Answer:

The  value is  d = 0.000125 \  m

Explanation:

From the question we are told that

   The  wavelength is  \lambda  =  500 \  nm =  500 *10^{-9 } \  m

    The  distance is of  the screen is  D =  2.0 \ m

    The  width of the fifth dark spot is y  =  4.00 \  cm  =  0.04 \  m

Generally the width of a fringe is mathematically represented as

           y =  \frac{ n  *  \lambda  *  D }{d }

=>        0.04  =  \frac{ 5  * 500 *10^{-9}  *  2 }{d}

=>        d =  \frac{ 5  * 500 *10^{-9}  *  2 }{0.04}

=>        d = 0.000125 \  m

الاضطراب العصبي يحدث بسبب ؟<br><br>​
tekilochka [14]

Explanation:

ا: قد يكون وراء هذه الظاهرة ميول وراثية، والتي تتسبب في صدور ردود فعل غير منتظمة في أماكن مختلفة معينة في الدماغ. تكون ردود الفعل هذه مسؤولة عن ظهور العلامات التي تميز العلامات المرافقة التي تظهر عند المرور في ظروف القلق.

ب: ان الفرضية السائدة والأساسية هنا، تقضي بأن العُصاب يظهر كردة فعلِ لفشل المنظومة النفسية الداخلية، في التأقلم مع القلق النابع من معاناة نفسية كبيرة. أو قد تنجم عن فشل المنظومة النفسية الداخلية في التأقلم مع الظروف الرضحية (التراجيدية) الخارجية والمحيطة.

ج:قد تظهر اضطرابات العُصابية من مزج بين تأثير التجارب الرضحية عند الطفولة، مع أسلوب الحياة المعاصر، والذي يتميز بوجود الإجهاد النفسي وبضعف الثقة بالمقومات الشخصية، الاجتماعية والاقتصادية
