What is 0.4 x 10 equals?
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.
Is x equals 3 a solution of x-7 equals 4?
no.. x equals 11
Y equals 4-x for x equals -6?
10
If x equals 5 and y equals 5 then 8x plus 4y equals?
(8 + 4) x 5...
Evaluate -2x2y if x equals - 4 and y equals 1?
16 lol?
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 = 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.
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?
Speed = (frequency) x (wavelength) = 23 x 4 = 92 meters per second
How many millimeters are there in a quarter of a meter?
250 mm 1/4 of a metre = 25cm 25cm = 250mm
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
What is the perimeter of a square if one side is 25cm long?
25cm x 4 sides = 100 cm perimeter
What beat frequency will occur when a 370 hz and a 374 hz sound source are sounded together?
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.
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 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.
