Which of the following represents the formation of a hypothesis a deep study of history of scientific thought b conscious observation of the world around us c algorithm devised to study nature systematically d factual understanding of living and nonliving things

Conscious observation of the world around us may lead to the
formation of a hypothesis, but it doesn't always have to.

Conscious observation of the world around us often leads to the reaction
of "Gee look at that !  That's weird.  I wonder what causes that." .

At THAT point, the observer may form the further thought: "Y'know what !
I'll just bet that when [THIS] happens, [THAT] happens." .

That thought is the hypothesis.

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

This is what a calorimeter is used for simpler ex, to measure calories in food.
