Answer:
Magnets interfere with compasses because compasses use the magnetic field to locate NESW (north east south west)
Explanation:
Answer:
Wavelength = 0.7083 meters
Explanation:
Given the following data;
Speed of wave = 340 m/s
Frequency = 480 Hz
To find how long is the sound wave, we would determine its wavelength;
Mathematically, the wavelength of a waveform is given by the formula;
Wavelength = velocity/frequency
Wavelength = 340/480
Wavelength = 0.7083 meters
90+66=156
156/2=78
Reply:78kilometers in 2 hours.
