State Bohr’s quantisation condition for defining stationary orbits.
Bohr’s quantization condition states that the angular momentum of an electron in a stationary orbit is quantized and given by mvr = nℏ, where m is mass, v is velocity, r is radius, and n is an integer. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-12/

What are the three types of sectional breathing techniques? Describe each briefly.
The three types of sectional breathing techniques are: Abdominal breathing: Directs breath to the diaphragm, enhancing deep breathing and relaxation. Thoracic breathing: Focuses on chest expansion, improving mid-lung efficiency and oxygenation. Clavicular breathing: Engages the upper chest or clavicRead more
The three types of sectional breathing techniques are:
See lessAbdominal breathing: Directs breath to the diaphragm, enhancing deep breathing and relaxation.
Thoracic breathing: Focuses on chest expansion, improving mid-lung efficiency and oxygenation.
Clavicular breathing: Engages the upper chest or clavicular area, aiding upper lung utilization.
These techniques collectively enhance lung capacity, promote better respiratory health, and foster mindfulness of breath.
List the guidelines for practicing Prānāyāma. Why are these important?
Prānāyāma guidelines emphasize breathing through the nose, relaxing the body, keeping the spine erect, observing abdominal movement, and practicing regularly. These ensure safety, proper technique, and effective outcomes. Maintaining a relaxed posture prevents strain, while observing abdominal movemRead more
Prānāyāma guidelines emphasize breathing through the nose, relaxing the body, keeping the spine erect, observing abdominal movement, and practicing regularly. These ensure safety, proper technique, and effective outcomes. Maintaining a relaxed posture prevents strain, while observing abdominal movement aids mindfulness. Regular practice develops deep, rhythmic breathing habits and enhances Prānāyāma’s physical and mental benefits. Following these guidelines maximizes its effectiveness and ensures a harmonious experience.

In formula format: ΔL = (F × L) / (A × Y) Where: - F= applied load which is the same for both the wires - L= length of wire which is the same for both - A= cross sectional area of the wire A = πd² / 4 - Y = Young's modulus (same material, so constant for both wires) The extension is **inversely propRead more
In formula format:
ΔL = (F × L) / (A × Y)
Where:
– F= applied load which is the same for both the wires
– L= length of wire which is the same for both
– A= cross sectional area of the wire A = πd² / 4
– Y = Young’s modulus (same material, so constant for both wires)
The extension is **inversely proportional to the cross-sectional area (A)
Step 1: Calculate the area ratio
For the first wire (diameter = d):
A₁ = (π × d²) / 4
For the second wire (diameter = 2d):
A₂ = (π × (2d)²) / 4 = (π × 4d²) / 4 = πd²
Area ratio is:
A₁ : A₂ = (πd² / 4) : πd² = 1 : 4
Step 2: Ratio of extensions
Since extension (ΔL) is inversely proportional to the area:
ΔL₁ : ΔL₂ = A₂ : A₁ = 4 : 1

Bhrāmarī Prānāyāma, or the “bee breath,” involves a gentle humming sound during exhalation. It calms the nervous system, reduces anxiety, and relaxes the mind. This practice fosters mindfulness, improves concentration, and balances emotions. Regularly practicing Bhrāmarī alleviates stress, enhances mental clarity, and promotes a state of calm. It is especially beneficial for individuals seeking to reduce mental fatigue and improve their emotional and mental well-being.
