Which statement best describes the interaction between earths magnetosphere and solar wind

Lenny wrote the steps he used to find the mass of an object with 400 J of energy moving at a velocity of 8 m/s. 1. Find the square of 8 m/s, which is 64 m2/s2. 2. Divide kinetic energy, 400 J, by 64 m2/s2, which is 6.25 J per m2/s2. 3. Divide 6.
