a wave is set up in a stretched string by pluck it. The velocity v, of the wave depends on the tension T in the string it's length L and mass M V=KTLyM. Where x, y,z are unknown and k=1 hence derive an expression relating V, T,L, M

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.

because if the tool that you are using is not balanced it there would be false mass.
