An object is placed 110 mm from a concave mirror with a focal length of 5.0 cm.

Approximately 92 mm.

Explanation:

Object's distance, u = 110 mm = 11 cm

focal length of the mirror = 5 cm

Image distance, v = ?

To determine the image distance, apply the mirror's formula;

= +

= -

   = -

   =

=

⇒ v =

       = 9.166667

v = 9.2 cm

The image distance is 92 mm.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .

a person with a mass of 106kg has a weight of 1060n
