During a science fair, a group of students came up with the following question: “Is color an inherent property in objects or is
it a product of the mind?” Why would this question be extremely difficult to answer scientifically? a. Color is not an observable phenomenon.
b. How people experience color is subjective.
c. It does not attempt to explain the natural world.
d. The experimental group would be too large.
I think the correct answer from the choices listed above is option B. The question that the group of students came up with would be an extremely difficult question to answer scientifically because how people see or experience color is subjective and people might see it differently.
The buoyant force must be greater to float, otherwise it would sink, its like a barrel in water, the more water weight in it the more it sinks, the more air weight the more it rises.
Explanation:when elevator does not move it reads weight of the person . when elevator moves up let apparent weight be F . W acts downwards so net force is F-W
