Answer:
mass
Explanation:
The mass only tells us the amount of a material. Density, melting points, and solubility are properties of a compound and will be different in this case.
object
focal point
2F position
The focal length is the distance from the mid-line of the lens to the Focal Point.
Focal point lies at a distance which is half the radius of curvature of the lens. hence focal length is also given by the formula
f = R/2
where f = focal length
R = radius of the focal length
hence the correct choice is focal point.
