What are the types of Āsanas introduced in this grade and what do they prepare the body for?
This grade introduces standing (Ardhakaṭicakrāsana), sitting (Padmāsana), prone (Bhujaṅgāsana and Shalabhāsana), and supine (Uttanapadāsana) Āsanas. Each type targets specific areas of the body, enhancing strength, flexibility, and balance. They also improve internal organ function and prepare the mRead more
This grade introduces standing (Ardhakaṭicakrāsana), sitting (Padmāsana), prone (Bhujaṅgāsana and Shalabhāsana), and supine (Uttanapadāsana) Āsanas. Each type targets specific areas of the body, enhancing strength, flexibility, and balance. They also improve internal organ function and prepare the mind and body for advanced Yoga practices, such as meditation. These foundational poses establish a solid base for cultivating physical, mental, and spiritual well-being.
See lessWhy is Padmāsana referred to as the destroyer of disease and a good meditative posture?
Padmāsana, or the Lotus Pose, is termed "the destroyer of disease" due to its benefits in improving blood circulation, stimulating abdominal organs, and calming the nervous system. It provides a stable base, helping practitioners maintain focus and balance. By reducing stress and fostering a meditatRead more
Padmāsana, or the Lotus Pose, is termed “the destroyer of disease” due to its benefits in improving blood circulation, stimulating abdominal organs, and calming the nervous system. It provides a stable base, helping practitioners maintain focus and balance. By reducing stress and fostering a meditative state, Padmāsana aligns the body and mind, making it a highly beneficial posture for health and spiritual growth.

Prānāyāma, derived from Yoga, is the practice of controlling and expanding the life force (Prāna) through regulated breathing. The word combines "Prāna" (life force) and "Ayāma" (control/expansion). This practice enhances energy flow, calms the mind, improves concentration, and promotes harmony. RegRead more
Prānāyāma, derived from Yoga, is the practice of controlling and expanding the life force (Prāna) through regulated breathing. The word combines “Prāna” (life force) and “Ayāma” (control/expansion). This practice enhances energy flow, calms the mind, improves concentration, and promotes harmony. Regular practice supports a healthy respiratory system and strengthens the connection between the body and mind, fostering overall physical and mental balance.
See lessWhat are the three important practices in Prānāyāma? Briefly describe each.
The three essential practices in Prānāyāma are: Puraka (Inhalation): A deep, controlled intake of breath to nourish the body. Rechaka (Exhalation): Slow, complete release of breath to expel toxins. Kumbhaka (Retention): Temporarily holding the breath, enhancing focus and energy flow. These practicesRead more

See lessPuraka (Inhalation): A deep, controlled intake of breath to nourish the body.
Rechaka (Exhalation): Slow, complete release of breath to expel toxins.
Kumbhaka (Retention): Temporarily holding the breath, enhancing focus and energy flow.
These practices collectively balance the breathing rhythm, improve lung capacity, and enhance physical and mental health.
A wire whose cross-sectional area is 2 mm² is stretched by 0.1 mm by a certain load, and if a similar wire of triple the area of cross-section is stretched by the same load, then the elongation of the second wire would be
The formula for the elongation of a wire is as follows: ΔL = (F L) / (A Y) Where: ΔL is the elongation, F is the force, L is the original length of the wire, A is the cross-sectional area, Y is Young's Modulus. For the first wire, the elongation is given by: ΔL1 = (F L) / (A1 Y) For the second wire,Read more
The formula for the elongation of a wire is as follows:
ΔL = (F L) / (A Y)
Where:
ΔL is the elongation,
F is the force,
L is the original length of the wire,
A is the cross-sectional area,
Y is Young’s Modulus.
For the first wire, the elongation is given by:
ΔL1 = (F L) / (A1 Y)
For the second wire, the elongation is given by:
ΔL2 = (F L) / (A2 Y)
Since the area of the second wire is three times that of the first wire, A2 = 3 A1, we can compare the elongations:
ΔL2 / ΔL1 = A1 / A2 = 1 / 3
Thus, the elongation of the second wire is one-third that of the first wire:
ΔL2 = ΔL1 / 3 = 0.1 mm / 3 = 0.033 mm
The correct answer is:
0.033 mm
