Answer 1

Explanation:

given

object distance= -10cm

focal length = 12cm

then image distance is

1/f=1/v-1/u

1/12=1/v-1/(-10)

1/12=1/v+1/10

1/v=1/12-1/10

1/v=5-6/60

1/v=1/-60

v=(-60)cm

Answer 2

Answer:

1)The image distance is-60

that means image is formed same side of the lens

2)Speciation is the process by which new species form. It occurs when groups in a species become reproductively isolated and diverge.
