Question
The sounds having a frequency of 20 Hertz to 20,000
Hertz are known as –Solution
An audio frequency is characterized as a periodic vibration whose frequency is audible to the average human. It is the property of sound that most determines pitch and is measured in hertz (Hz). The generally accepted standard range of audible frequencies is 20 to 20,000 Hz, although the range of frequencies individuals hear is greatly influenced by environmental factors.
? = 6.25% of 240 + 25 2 + 17 2 – 16 × 17
1440 ÷ 12 + 540 ÷ √36 + ? = 180 * 3
Simplify the given expression:-
What will come in the place of question mark (?) in the given expression?
(24 2 – 16 2 ) + 75% of 40% of 480 = ?
(22 + √3364)/(? + 4) = 10
I. x² + 3x – 154 = 0
II. y² + 5y – 126 = 0
35% of 500 × 22% of ? = 847
32 × 3 (54 – 15) + 186 ÷ 3 ÷ 2 – (21)² =?
666(2/3)% of 30 - 116(2/3)% of 90 =?
√(?) ² = √7396 - √6889
