The heat produced by 100 W heater in 2 ntinutes is equal to
Heat produced is given by Q = P × t. Gives P = 100W and t = 2minutes = 120s, we get: Q = 100 × 120 = 12000J = 12.0KJ Answer: (c) 12.0 kJ. For more visit here: https://www.tiwariacademy.com/ncert-solutions/class-12/physics/chapter-3/

Musical instruments are crafted using various materials, each influencing the instrument’s tone. Wood is commonly used in guitars and violins due to its resonant properties. Metal is used in trumpets and cymbals for bright, sharp sounds. Clay is used in instruments like the ghatam, providing a deep percussive tone. Natural materials like gourds are used in instruments such as the sitar, which enhances resonance. The material plays a crucial role in shaping the instrument’s sound characteristics.

Different playing techniques depend on the instrument’s design and sound production. Bowed instruments like the violin use a bow to create continuous vibrations, allowing smooth, flowing melodies. Percussion instruments, such as tabla and drums, require sticks or fingers to produce beats. Plucked inRead more
Different playing techniques depend on the instrument’s design and sound production. Bowed instruments like the violin use a bow to create continuous vibrations, allowing smooth, flowing melodies. Percussion instruments, such as tabla and drums, require sticks or fingers to produce beats. Plucked instruments, like the sitar, use fingers to generate precise notes. Each method ensures the best tonal quality for the instrument, making it suitable for its role in a composition.

The variation in pitch when striking jaltarang bowls depends on the amount of water in each bowl. A bowl with more water vibrates at a lower frequency, producing a deeper sound, while a bowl with less water vibrates faster, creating a higher pitch. This principle allows musicians to arrange the bowlRead more
The variation in pitch when striking jaltarang bowls depends on the amount of water in each bowl. A bowl with more water vibrates at a lower frequency, producing a deeper sound, while a bowl with less water vibrates faster, creating a higher pitch. This principle allows musicians to arrange the bowls in a musical scale and produce melodies. The technique of striking each bowl gently or forcefully can also impact the sound quality and intensity, making the instrument versatile.
See lessHow do instruments contribute to the layering of sound and rhythm in music?
Musical instruments contribute to the layering of sound by adding distinct elements such as melody, harmony and rhythm. Each instrument plays a unique role in shaping the overall musical piece. Rhythm instruments set the beat, melody instruments carry the tune and harmonic instruments enhance depth.Read more
Musical instruments contribute to the layering of sound by adding distinct elements such as melody, harmony and rhythm. Each instrument plays a unique role in shaping the overall musical piece. Rhythm instruments set the beat, melody instruments carry the tune and harmonic instruments enhance depth. When combined, these elements create a well-balanced composition that evokes emotions and captures listeners’ attention, making music more engaging, expressive and memorable for audiences.
