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
The wave speed can be calculated by multiplying the frequency by the wavelength. In this case, the wave speed would be 92.0 m/s (23.0 Hz x 4 m).
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
Frequency = (speed)/(wavelength) = (12 cm/sec) / (3 cm) = 4/second = 4 Hz
Speed = (wavelength) x (frequency) = (3 x 4) = 12 meters per second
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.
The speed of a wave can be calculated using the formula: speed = wavelength x frequency. In this case, the speed of the wave would be 32 cm/s (4 cm x 8 Hz).
