    A noticeable difference exists in musical preferences between younger and older generations. Children and teenagers often lean toward modern pop, electronic beats and energetic fusion tracks that mirror dynamic social trends and enthusiasm. Conversely, elders frequently prefer classical, semi-classical or spiritual melodies because their deeper life experiences draw them toward calmness, intricate traditional structures and thoughtful contemplation.

    Governments enforce price controls on life-saving medicines, hospital equipment, baby food and hand sanitisers under essential commodity regulations to prevent black-marketing and ensure affordability for vulnerable citizens. Additionally, price floors such as minimum support prices for wheat and paddy ensure farmers receive fair remuneration. These interventions aim to maintain social equity, public health, food security and market transparency during crises.

    Excessive government intervention harms economic growth by distorting price signals and lowering producer incentives. For example, capping crop prices below actual farming costs discourages farmers from expanding production, resulting in agricultural deficits. Moreover, heavy compliance burdens involving multiple permits, safety inspections and clearance certificates increase operating costs for small enterprises, diminishing the ease of doing business and discouraging technological innovation and entrepreneurship.

  4. Given blade length r = 28 cm, angle of sweep θ = 120° and number of wipers = 2. Area swept by one wiper blade: Area = (θ / 360) x π x r² Area = (120 / 360) x (22/7) x 28 x 28 Area = (1/3) x 22 x 4 x 28 = 2464 / 3 cm². Total area cleaned by both wipers: Total Area = 2 x (2464 / 3) = 4928 / 3 cm². InRead more

    Given blade length r = 28 cm, angle of sweep θ = 120° and number of wipers = 2.

    Area swept by one wiper blade:

    Area = (θ / 360) x π x r²

    Area = (120 / 360) x (22/7) x 28 x 28

    Area = (1/3) x 22 x 4 x 28 = 2464 / 3 cm².

    Total area cleaned by both wipers:

    Total Area = 2 x (2464 / 3) = 4928 / 3 cm².

    In decimal form, 4928 / 3 is approximately 1642.67 cm².

    Thus, total area cleaned is 4928/3 cm² (or 1642.67 cm²).

  5. Given r = 15 cm, θ = 60°, π = 3.14 and √3 = 1.73. Total circle area = π x r² = 3.14 x 15² = 3.14 x 225 = 706.5 cm². Area of minor sector = (60 / 360) x 3.14 x 225 = (1/6) x 706.5 = 117.75 cm². The triangle formed is equilateral (angle 60°): Area of triangle = (√3 / 4) x r² = (1.73 / 4) x 225 = 97.31Read more

    Given r = 15 cm, θ = 60°, π = 3.14 and √3 = 1.73.

    Total circle area = π x r² = 3.14 x 15² = 3.14 x 225 = 706.5 cm².

    Area of minor sector = (60 / 360) x 3.14 x 225 = (1/6) x 706.5 = 117.75 cm².

    The triangle formed is equilateral (angle 60°):

    Area of triangle = (√3 / 4) x r² = (1.73 / 4) x 225 = 97.3125 cm².

    Minor segment = Minor sector – Triangle = 117.75 – 97.3125 = 20.4375 cm² (or 20.44 cm²).

    Major segment = Circle area – Minor segment = 706.5 – 20.4375 = 686.0625 cm² (or 686.06 cm²).
