Answer:
The sine waves of the two waves should look the same.
Explanation:
The sine wave formula for a sound wave is given as
y = A sin[2πft + θ]
where
y = The displacement of the wave at time t.
A = amplitude or maximum displacement of the wave during its progression.
t = time
f = frequency of the wave
θ = phase angle/phase shift of the wave which is normally 0 for sound waves
From this information,
It is evident that it is the frequency and time that dictate the exact motion of the wave or behaviour of the waveform. The amplitude only dictates the extent of the wave.
And if the frequency of 2 waves A and B are similar, then even a very different Amplitude cannot change the fact that the two waves will behave similarly, have the same sine curve and have the same movements as the time of progression increases.
Even if the phase angle isn't zero, whatever it is, will not change the fact that the two waves will appear similar to each other, only separated by that phase angle.
Hence, the two waves will look very similar with only the amplitude that shows the extent of displacement, different.
Hope this Helps!!!
False because anti-lock brake system will activate automatically.
-- The amplitude of Wave-1 is greater than the amplitude of Wave-2 ...
possibly 3 or 4 times as great.
-- The wavelength of Wave-1 is longer than the wavelength of Wave-2 ...
maybe almost twice as long.
-- The frequency of Wave-2 is greater than the frequency of Wave-1 ...
maybe almost twice as frequent.
Answer:
The three balls would hit the ground at the same time.
Explanation:
As Galileo Galilei proved with an experiment in which he put in free fall different objects of different mass, but the same shape, all objects fall with the same acceleration when are allowed to free falling. So, if the initial conditions were the same (height, initial velocity, and time), the three balls would hit the ground at the same time, no matter which material they are made of.
