Hydroboration-oxidation an acid catalyzed hydration of an alkene will lead to the same product when applied to the alkene below

Product will not be the same because hydroboration-oxidation follows anti-Markovnikovs rule and acid catalyzed hydration follows Markovnikov's rule.
Markovnikov's rule - hydrogen becomes attached to the carbon with more hydrogen substituents, and the OH group becomes attached to the carbon with more alkyl substituents.

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.
