What is the speed in ms of a wave on a cord if it has a wavelength of 4 m and a period of 0.5 s?
The speed of a wave on a cord is calculated as the product of its wavelength and frequency. The formula is v = Ī» * f, where v is the wave speed, Ī» 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.
What is the frequency of a wave that has a speed of 8 ms and a wavelength of 2.0 m?
4 Hz
What is the wave speed of a wave that has a frequency of 23.0 Hz and a wave length of 4 m?
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).
A 6 pole induction motor is connected to a 415v50hz mainsIt runs at a speed of 960 rpmCalculate the answer of synchronous speed?
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
How many millimeters are there in a quarter of a meter?
250 mm 1/4 of a metre = 25cm 25cm = 250mm
What is the speed of a wave with the wavelength of 3 m and a frequency at 4 hz?
Speed = (wavelength) x (frequency) = (3 x 4) = 12 meters per second
What is the frequency of a wave has a speed of 12cm and a wavelength of 3 cm?
Frequency = (speed)/(wavelength) = (12 cm/sec) / (3 cm) = 4/second = 4 Hz
What is the perimeter of a square if one side is 25cm long?
25cm x 4 sides = 100 cm perimeter
What is synchronous speed?
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.
How fast is a wave moving if it has a frequency of 10 Hz and there are 4 meters between crests?
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.
A wave with a frequency of 14 hz has a wavelength of 3 meters At what speed will this wave travel?
The speed of a wave is the product of its frequency and its wavelength.
Find the speed of a wave with frequency of 3 Hz and a wavelength of 2 m?
The answe would be 12. Because, the equation for wave speed (v) can be calculated using wavelength (Ī») and frequency (f): vĀ = Ī» Ć f. For example, to determine the wave speed of a wave that has a wavelength of 5 m and a frequency of 4 Hz, replace the Ī» and f with the values given and solve:Ā vĀ = 5 m Ć 4 Hz = 20 m/s. So all you have to do is multiply .
