Frequency is the number of occurrences of a repeating event per unit of time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency. Frequency is measured in units of hertz which is equal to one occurrence of a repeating event per second. Formula of Frequency is f = 1/T (f=frequency and T = period).
Find the simplified value of the following expression:
62 + 122 × 5 - {272 + 162 - 422}
18 × √225 + 378 ÷ √441 = ? × 9
Train M, ‘x’ metres long crosses (x – 30) metres long platform in 22 seconds while train N having the length (x + 30) metres crosses the same plat...
(2197)1/3 + (18)2 − 121 = ? − 69 × 5
{(5/8) + (4/5)} × (?/19) = 33
24.5% of 400 + 528 of 12.5 ÷ 11
Simplify the expression -:
17% of 250 + ? = 108
?2 = √20.25 × 10 + √16 + 32
25639 – 5252 – 3232 = ?
