100cm/s
To calculate 0.4 multiplied by 10, you simply move the decimal point of 0.4 one place to the right, resulting in 4. Therefore, 0.4 x 10 equals 4.
no.. x equals 11
10
(8 + 4) x 5...
16 lol?
The speed of a wave on a cord is calculated as the product of its wavelength and frequency. The formula is v = λ * f, where v is the wave speed, λ is the wavelength, and f is the frequency. Given a wavelength of 4 m and a period of 0.5 s (which equals a frequency of 1/0.5 = 2 Hz), the speed of the wave would be v = 4 m * 2 Hz = 8 m/s.
4 Hz
Speed = (frequency) x (wavelength) = 23 x 4 = 92 meters per second
250 mm 1/4 of a metre = 25cm 25cm = 250mm
Answer 1000 RPM or 16.667 HZ, 50 Hz * 60 = 3000 RPM 3000 / 3 = 1000 RPM, or 50 HZ / 20 (1/3 of 50 Hz) * 60 seconds. Or Hz * 20 ( converts to RPM) For 4 pole then, Hz * 30 = RPM For 8 pole, Hz * 15 = RPM
25cm x 4 sides = 100 cm perimeter
The beat frequency occurs when two sound waves of slightly different frequencies are played together, and it is calculated by taking the absolute difference between the two frequencies. In this case, the beat frequency is |374 Hz - 370 Hz|, which equals 4 Hz. Therefore, a beat frequency of 4 Hz will be heard when the 370 Hz and 374 Hz sound sources are sounded together.
Speed = (wavelength) x (frequency) = (3 x 4) = 12 meters per second
Frequency = (speed)/(wavelength) = (12 cm/sec) / (3 cm) = 4/second = 4 Hz
The speed is determined by the supply frequency and that must be divided by the number of pole-pairs. So a 4-pole motor would run at 1500 rpm on 50 Hz or 1800 rpm on 60 Hz.
The wave speed can be calculated using the formula: speed = frequency x wavelength. Given the frequency of 10 Hz and a wavelength of 4 meters between crests, the speed of the wave would be 40 m/s.
The speed of a wave is the product of its frequency and its wavelength.
