Select and rewrite the appropriate disorder of the respiratory system based on the given symptoms:
Given disorders: \[ {[ Sinusitis, Emphysema, Silicosis and Asbestosis, Laryngitis ]} \]
(a) Breakdown of alveoli, shortness of breath.
(b) Inflammation of the sinuses, mucous discharge.
(c) Inflammation of larynx, vocal cords, sore throat, hoarseness of voice, mucous build-up,
and cough.
(d) Inflammation of fibrosis, lung damage.
The respiratory disorders listed above are classified based on their symptoms and causes:
1. Emphysema: A chronic obstructive pulmonary disease (COPD) where alveolar walls break down, reducing oxygen exchange efficiency.
2. Sinusitis: Inflammation of the sinus cavities due to infection or allergy, leading to nasal congestion and mucus buildup.
3. Laryngitis: Swelling of the larynx, usually caused by infections, excessive voice use, or irritants, affecting speech and causing hoarseness.
4. Silicosis and Asbestosis: Caused by prolonged inhalation of fine particles of silica or asbestos, leading to lung fibrosis, reduced lung function, and respiratory distress.
Interpret the given diagrams A and B. Enlist the changes occurring during inspiration and expiration.
Derive an expression for energy stored in a charged capacitor. A spherical metal ball of radius 15 cm carries a charge of 2μC. Calculate the electric field at a distance of 20 cm from the center of the sphere.
Draw a neat labelled diagram of Ferry's perfectly black body. Compare the rms speed of hydrogen molecules at 227°C with rms speed of oxygen molecules at 127°C. Given that molecular masses of hydrogen and oxygen are 2 and 32, respectively.
Distinguish between an ammeter and a voltmeter. (Two points each).
The displacement of a particle performing simple harmonic motion is \( \frac{1}{3} \) of its amplitude. What fraction of total energy is its kinetic energy?
Using the geometry of the double slit experiment, derive the expression for the fringe width of interference bands.
An alternating voltage is given by \( e = 8 \sin(628.4 t) \).
Find:
(i) Peak value of e.m.f.
(ii) Frequency of e.m.f.
(iii) Instantaneous value of e.m.f. at time \( t = 10 \, {ms} \)
