Answer:
D. The frequency is not affected as the volume of sound increases
Explanation:
Volume of the sound is defined by the amplitude of the wave or how loud a sound is whereas Frequency is basically the pitch of the sound and is inversely proportional to the wavelength . Increasing frequency will increase the pitch of the sound without affecting it's volume.
4.22
Explanation:
The most acidic rainfall in New York State will have pH of 4.22 whereas the least acidic will be that of 4.40.
The pH scale expresses the acidity or alkalinity of aqueous solutions.
- The pH scale ranges from 1 to 4
- An acidic solution will have a pH value less than 7
We have given a range of values between 4.22 to 4.40
This implies that the pH values of rainfall in this region falls between these extremes.
The least value 4.22 is the most acidic
The value 4.4 is the the least acidic
The lower the pH value, the more acidic a solution is.

Explanation:
Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties:
Frequency, or its inverse, wavelength.
Amplitude, sound pressure or Intensity.
Speed of sound.
Direction.
It causes a movement of convection in the water resulting in a pulling current.

Answer:
F = 294.3 [N]
Explanation:
To solve this problem we must use Newton's second law which tells us that force is equal to the product of mass by acceleration. It is this particular case the acceleration is due to the gravitational acceleration since the body is in free fall.
Therefore we have:
F = m*g
where:
F = force [N]
m = mass = 30 [kg]
g = gravity acceleration = 9.81 [m/s^2]
F = 30*9.81
F = 294.3 [N]
