Watch them and make sure they dont gop out in the street because they will die
Answer:
The time is 176 seconds
Explanation:
We use the formula:
V= d/t V=velocity, d= distance, t= time
259 m/s= 45683 m/ t
t= 45683 m// 259 m/s
t= 176, 3 seg
That represents a proton!
The wavelength of a wave of frequency 4 Hz and speed 2 m/s is 0.5 m.
Answer:
Explanation:
As we know that speed of a wave is directly proportional to the product of wavelength and frequency of the wave. If any two variables are known, then we can easily find the third parameter.
Like, in this case, the wavelength is not given, instead the frequency is given as 4 Hz and speed is given as 2 m/s, so the wavelength can be easily determined.
Speed = Wavelength × Frequency
Then Wavelength = speed/frequency
So, wavelength = 2/4=0.5 m
Thus, the wavelength of a wave of frequency 4 Hz and speed 2 m/s is 0.5 m.
