- A deep sea ocean vessel uses SONAR to
detect the ocean's bottom. Sound waves are
emitted from the surface of the ocean and
travel through the water at 1450 m/s. The
ocean bottom is 1630 m below the surface.
Determine the amount of time that passes
before the sound waves are reflected back to
the surface.

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.
