The wavelength of a wave on a string is 1.2 meters. if the speed of the wave is 60 meters/second, what is its frequency? a. 0.20 hertz b. 2.0 hertz c. 50 hertz d. 10 hertz e. 15 hertz

C. 50Hz. The wavelength of a wave on a string is 1.2m with a speed of 60m/s its frecueny is 50Hz.

The wavelength of a wave describes how long the wave is, and can be represented by the formula λ = v/f, where λ is the wavelenght in meters, v is the speed of the wave in m/s, and f is the frecuency of the wave in Hertz.

The wavelength of a wave on a string is 1.2m and its speed is 60m/s, to calculate its frecuency we have to clear f from the equation λ = v/f. So:

f = v/λ

f = (60m/s)/(1.2m)

f = 50 1/s = 50Hz

answer: d. a cme increases the amount of energy in the solar wind

explanation:

coronal mass ejections, also called cmes, are large clouds of plasma and magnetic field that erupt from the sun. only when the cloud is aimed at earth will the cme hit earth and therefore cause impacts. high-speed solar wind streams come from areas on the sun known as coronal holes.

the part of the wave he is travelling on is the crest
