Answer:
The wavelength of wave is 2.78 m.
Explanation:
Frequency of a wave is 90 Hz
Speed of a wave is 250 m/s
It is assume to find the wavelength of wave. The formula of speed is given by :
So, the wavelength of wave is 2.78 m.
Direct evidence is evidence heard from a witness about the subject in question. For instance, if there is a terrorist attack carried out by an independent person, the people close to them could supply crucial evidence, such as if they were acting weirdly in the past month. Hope this helped!
2nd stone time = 13.0/9.8 = 1.33 seconds
distance = 0.5*9.8*1.33^2 = 8.67 meters
1st stone time = 1.33+1.5 = 2.83 seconds
distance = 0.5*9.8*2.83^2 = 39.24 meters
39.24-8.67 = 30.57 meters apart
