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

puteri [66]

Answer:

v_2=4.53m/sv_2=4.53m/s

Explanation:

In order to solve the exercise it is necessary to apply the energy conservation equation,

The equation says the following,

mgdsin(\theta)+\frac{1}{2}mv^2_1=\frac{1}{2}mv^2_2+\frac{1}{2}Iw^2

Replacing the formula for I of a sphere, we have

mgdsin(\theta)+\frac{1}{2}mv^2_1=\frac{1}{2}mv^2_2+\frac{1}{2}\frac{2}{5}mr^2(\frac{v_2}{r})^2

mgdsin(\theta)+\frac{1}{2}mv^2_1=\frac{1}{2}mv^2_2+\frac{1}{5}mv^2_2=\frac{7}{10}mv^2_2

\frac{10}{7}gdsin(\theta)+\frac{5}{7}v^2_1=v^2_2

In this way we get the expression

v_2=\sqrt{\frac{10}{7}gdsin(\theta)+\frac{5}{7}v^2_1}

We proceed to replace with the given values and obtain that

v_2=\sqrt{\frac{10}{7}*9.8*3sin(26))+\frac{5}{7}*1.75^2}

v_2=4.53m/s
