Answer:
The percentage change in frequency is 10%.
Explanation:
Given that,
Amplitude decreases by 1/10 per second.
Resonance = 10 Hz
We need to calculate the change in frequency
Using formula of change in frequency
Put the value into the formula
We need to calculate the resonant frequency
Using formula of resonant frequency
Put the value into the formula
We need to calculate the percentage change in frequency
Using formula of percentage change in frequency
Hence, The percentage change in frequency is 10%.

Im afraid i cant help u if we can’t see the image u r working with. could u provide an image of the question?
SOLUTION:
1 minute = 60 seconds
1 second = 1 metre
1 × 60 = 1 × 60
60 seconds = 60 metres
1 minute = 60 metres
Therefore, the horse can gallop / travel 60 metres in 1 minute.
Hope this helps! :)
Have a lovely day! <3
Wave speed = frequency * wavelength
Input the numbers into this equation :
Wave speed = 200 * 3
Work it out and you will get the answer :
Wave speed = 600 m/s
