Air pressure is proportional to the square of the wind velocity.
Wind speed is how fast wind goes and atmospheric pressure is the pressure that the atmosphere pushes on us. The greater the difference in barometric pressure from a high pressure zone to a low pressure zone, the greater the wind velocity will be.
Hope this helped!
Answer:
899752.13598 N
Explanation:
p = Pressure on the plate = 
A = Area = 
F = Force on the region
When force is divided by area we get pressure

Force is exerted by the atmosphere on a disk-shaped region is 899752.13598 N
Answer:
So percentage error will be 2 %
Explanation:
We have given initial value of acceleration due to gravity 
And final value of acceleration due to gravity 
We have to find the percentage error
We know that percentage error is given by 
So
%
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.
