Three common postures in classical dance are Samabhanga (symmetrical stance), Tribhanga (three bends at neck, torso and knee) and Abhanga (slight sideways tilt). Each posture contributes to storytelling, balance and expressive movement in different Indian classical dance traditions. Class 6 Arts ...

Let the length of each wire be L. For the square, side = L/4; area = (L/4)² = L²/16. For the circle, radius = L/2π; area = π(L/2π)² = L² /4π. Ratio of magnetic moments = L²/4π/L²/16 = 16/4π = ...
Voltage sensitivity is given by ls/R’ where I s is current sensitivity. If current sensitivity increases by 20% and resistance by 25%, voltage sensitivity changes by 120/125 = 0.96, i.e., decreases by 4%. The answer is (D) Decrease by ...
To remove the tension in the supporting strings, the magnetic force (BIl) should balance the gravitational force (mg). Therefore, equating BIl = mg, the current required is I = mg/Bl. Hence, the Correct answer is (c) mg/lB.
A current-carrying wire kept in a uniform magnetic field will experience a maximum force when it is perpendicular to the magnetic field. This is because the magnetic force is given by F = Bill sin θ and sin 90° = ...
