"a string on a musical instriment vibrates at a frequency of 210 hertz. if the string has a wavelength of 2.07m, what is the velocity of the wave?"

Velocity of wave = 434.7 m/s

Explanation:

Given:

Frequency of musical instrument = 210 hertz

Wavelength of string = 2.07 meter

Find:

Velocity of wave

Computation:

Velocity = Frequency x Wavelength

Velocity of wave = Frequency of musical instrument x Wavelength of string

Velocity of wave = 210 x 2.07

Velocity of wave = 434.7 m/s

where's the following? you gotta add it to know what the choices are

explanation:

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 .
