Explain why galileo's thought experiment about the ball rolling forever on a level surface could only be a thought experiment.

It could only be a thought experiment because there is always friction on the surface in the real world. The friction would cause the ball to slow down and eventually stop.

Hope this helps :)

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.

True is ur answer : )
