If a transverse wave has a velocity of 27.9 meters per second and a wavelength of 200 meters, what is the waves
frequency?

0.14Hz

Explanation:

Given parameters:

Velocity  = 27.9m/s

Wavelength  = 200m

Unknown:

Frequency of the waves = ?

Solution:

To solve this problem, we use the wave - velocity equation:

          V  = F ∧  

V is the velocity

F is the frequency

∧ is the wavelength

 Now, let us insert the parameters and solve;

So;

              27. 9  = F x 200

                  F  = 0.14Hz

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
