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.
Supposing the runner is condensed to a point and moves upward at 2.2 m/s. It takes a time = 2.2/g = 2.2/9.8 = 0.22 seconds to increase to max height. Now looking at this condition in opposite - that is the runner is at max height and drops back to earth in 0.22 s (symmetry of this kind of motion). From what height does any object take 0.22 s to fall to earth (supposing there is no air friction)? d = 1/2gt²= (0.5)(9.8)(0.22)²= 0.24 m
