1.) Use the formula to solve -
1/f = 1/do + 1/di; Where f = focal length; 1/do + 1/di
1/f = 1/do + di
1/8 = 1/25 + 1/?
.125 = .04 + 1/di
.125 -.04 = 1/di (transferred .04 to the left side of the equation)
.085/1 = 1/di
.085di/.085 = 1/.085 (multiplied both sides by di and divided both sides by .085)
di = 11.76 or 12
2.) Therefore, 12 cm is the distance from the image to the mirror
The number that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.
<h3>What is regional metamorphism?</h3>
Regional metamorphism occurs when rocks undergoes changes as a result of high temperatures and pressure deep within the earth's crust.
Regional metamorphic rocks are usually foliated or squashed in appearance.
Examples of regional metamorphism rocks are schist and gneiss rocks.
Therefore, the figure that indicates typical continental conditions (regional metamorphism) is that showing schist and gneiss rocks.

The third option is wrong
i believe i could be wrong but i think its kinetic energy.
