please solve ..............​

Answer 1

sorry i dont know

mark me BRAINLIEST

Answer 2

Height of object = 1 cm

U = - 15 cm

f = - 10 cm

Size of image =?

V =?

Nature =?

By mirror formula

$\frac{1}{f} = \frac{1}{v } + \frac{1}{u} \\ \frac{1}{ - 10 } = \frac{1}{v} + \frac{1}{( - 15)} \\ \frac{1}{ - 10} + \frac{1}{15 } = \frac{1}{v} \\ \frac{ - 1}{30 } = \frac{1}{v} \\ v = - 30$

Nature :Negative sign shows that the image is formed front of the mirror. And the image is real and inverted.

$\frac{height \: of \: image}{height \: of \: object} = - \frac{v}{u} \\ height \: of \: image \: = \frac { - v}{u} \times height \: of \: object \\ height \: of \: image \: = \frac{ - ( - 30)}{ - 15} \times 1 \\ height \: of \: image \: = - 2$

Thus the size of image is 2 cm.

thus the image is real and inverted
