Distance in a minute=<span>0.5 times 30=15 meters
distance in a second</span><span>=15 divided by 60=0.25 meters per second
hope it helps</span>
Answer:
They two waves has the same amplitude and frequency but different wavelengths.
Explanation: comparing the wave equation above with the general wave equation
y(x,t) = Asin(2Πft + 2Πx/¶)
Let ¶ be the wavelength
A is the amplitude
f is the frequency
t is the time
They two waves has the same amplitude and frequency but different wavelengths.
It will have the strongest attraction for a conductor.
I feel that they should be regulated, mostly because its not safe for your ears to listen to such loud music. For example, if you were in the front of the concert you are more likely to get damage of your hearing more then the people in the back who have a slight chance.
Now, our ears can only handle up to 85 dB, thats why when you shoot a gun in a shooting range (if you've been at one) you wear hearplugs to protect you from the roughly 140-dB it gives off when fired. At rock concerts roughly 120-dB only 35-dB higher then what we are able to handle. The limit should be at most 90 dB because it is not too high and wont give us full on hearing damage to us in the future.
