Schools can promote musical learning by introducing regular music classes, providing access to instruments and hiring trained instructors. Organizing music competitions, talent shows and workshops with professional musicians can inspire students. Forming school bands and orchestras allows students to perform, boosting confidence. Music should be integrated into the curriculum to emphasize its importance. Financial assistance or scholarships for instrument learning can further encourage participation, making music education more accessible and appealing to students.

In a potentiometer experiment, the internal resistance of the cell can be determined using the formula: L₁/L₂ = r + R/r where L₁ is the original balancing length, L₂ is the new balancing length, r is the internal resistance, and R is the external resistance. Substituting the values, we get r = 3Ω. TRead more
In a potentiometer experiment, the internal resistance of the cell can be determined using the formula:
L₁/L₂ = r + R/r
where
L₁ is the original balancing length, L₂ is the new balancing length,
r is the internal resistance, and R is the external resistance. Substituting the values, we get
r = 3Ω. Therefore, the internal resistance is 3 Ω. The correct answer is (c) 3 Ω.

When two resistances R₁ and R₂ are connected in series, they consume 12 W power. When they are connected in parallel, they consume 50 W power. What is the ratio of the Power of R₁ and R₂?
Let P₁ and P₂ be powers across R₁ and R₂. In series, power is divided inversely as resistance. In parallel, power is directly proportional to conductance. Using given conditions and solving equations, the ratio P₁ /P₂ = 4. Answer: (b) 4. For more visit here: https://www.tiwariacademy.com/ncert-solutRead more
