Answer:
Frequency of the wave is 3.8 hertz.
Explanation:
It is given that, the sinusoidal wave has following wave equation as :
The general equation for the sinusoidal wave is :
Where
A is the amplitude
k is the constant
is the angular frequency
is the phase difference
Since,
or
f = 3.8 Hz
So, the frequency of the wave is 3.8 hertz. Hence, this is the required solution.
Answer:
The speed of the 1 kg red ball 8.04 m/s .
Explanation:
Given :
Separation between rods , d = 1.5 m .
Mass of the red ball is 1 kg .
Mass of the orange ball is 5.7 kg .
Angular velocity , .
Now , distance of center of mass from red ball is :
We know , speed is given by :
Hence , this is the required solution .
