Marge read that the universe is expanding and the galaxies are moving apart. this, the book says, is similar to how raisins and nuts placed on dough spread out when the dough rises. what is a likely misconception this could cause in marge’s mind? a- the galaxies are shaped like raisins b- the universe will expand forever c- there are galaxies beyond the known universe d- galaxies are found only in the outer part of the universe

A misconception that this example could cause it that galaxies are found only in the outer part of the universe. Galaxies have various shapes, oval, spiral, double spiral (like our own galaxy) and explaining them like raising could make someone thinks that they are only in the outer part of the universe, like raisins. Beside from this fact, the example is a clear method to explain the expansion of the universe, and how galaxies are going apart from each other.

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
