When the Sun is directly overhead, the intensity of sunlight reaching the ground is about 1000 W/m^{2} 2 . The Earth has a radiu
s of about 6400 km. What is the total power associated with sunlight shining on the Earth?

The speed of sound, c, is given by the Newton-Laplace formula
where
K = bulk modulus
ρ = density
Because the density is constant, the speed of sound is proportional to the square root of the bulk modulus.
Therefore when the bulk modulus increases, the speed of sound increases by the square root of the bulk modulus.
For example, if K is doubled, then
Answer:
If the bulk modulus increases by a factor of n, then c increases by a factor of √n.
