I need someone smart! why is the multiverse considered a theory if it has no observational or experimental evidence?
shouldn't it be considered a plausible hypothesis instead, sense it has no evidence but is lickely the case?

Because its reliable.   there is no pollution  the chances of a radiation leak is low

What does the start look like

One answer could be erosion

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.
