The spacecraft was moved closer to the launcher by the same amount Wednesday as it was on Tuesday, and yet its speed went up much more. Claim 3 suggests that the magnetic force was much stronger on Wednesday than on Tuesday.Consider the two subclaims for Claim 3 and answer the question below.Claim 3.A: The magnetic force was much stronger on Wednesday because the magnet was stronger.Claim 3.B: The magnetic force was much stronger on Wednesday because the magnetic force is stronger closer to the magnets.Which claim do you think is more convincing, and why?
