Multiple lines of evidence demonstrate that the Moon is a solid body which formed from an impact between Earth and a planetoid. Historically, it was theorized that the Moon originated when a rapidly-spinning Earth expelled a piece of its mass. This was proposed by George Darwin (son of the famous biologist Charles Darwin) in 1879 and retained some popularity unt… NettetThe answer I got was -1. I calculated this by taking the straw, which has 1 hole, then covering one end, which would make it have 0 holes (if you stretched it out enough it would become a plate) then if you cover the other end you lose a hole again, so you would have -1 holes. A sphere has one “two dimensional” hole.
