Atoy car is placed 29.0cm from a convex mirror. the image of the car is upright and one-sixth as large as the actual car. calculate the mirror's power in diopters.

Suppose that three astronomical objects, 1, 2, and 3 are observed to lie on a line, and the distance from object 1 to object 3 is d. object 1 has four times the mass of object 3, and seven times the mass of object 2. find the distance between objects 1 and 2 for which the net force on object 2 is zero.
