Answer:

The families are thought to form as a result of collisions between asteroids. In many or most cases the parent body was shattered, but there are also several families which resulted from a large cratering event which did not disrupt the parent body (e.g. the Vesta, Pallas, Hygiea, and Massalia families).

professor190 [17]

Answer:

77.625 cm

Explanation:

The given distance of the image behind the convex mirror, v = 11.5 cm

The focal length of the mirror, f = 13.5 cm

The mirror formula for convex mirror is given as follows;

$\dfrac{1}{u} - \dfrac{1}{v} = -\dfrac{1}{f}$

Where;

u = The distance from the statue to the mirror

Therefore, we get;

$\dfrac{1}{u} = -\dfrac{1}{f} + \dfrac{1}{v}$

Plugging in the values gives;

$\dfrac{1}{u} = -\dfrac{1}{13.5} + \dfrac{1}{11.5} = \dfrac{8}{621}$

∴ The distance from the statue to the mirror, u = 621/8 cm = 77.625 cm.
