Staying abstinent can keep you free of sexually transmitted diseases and also keep your mental, emotional, and physical state as good as possible! At a young at(teens-20) sexual activity can actually harm some bodies, as they are not yet ready and matured enough. Also, when you are young it is hard enough to be emotionally stable, let alone having had sex and be emotionally stable. Remember there is always the word no, and places to stop. You can have a friend and a safeword for them to come get you etc. <span />
Answer:
50 cm
Explanation:
Given that
Focal length of the mirror, f = 25 cm
Distance of the image, u = ?
Distance of the object, v = 50 cm
The formula for the focal length of a convex mirror is given by the relation
1/f = 1/u + 1/v,
where each of the parameters are exactly the same as what I've defined above. So now, if we plug in the values, we have
1/25 = 1/u + 1/50
1/u = 1/25 - 1/50
1/u = (2 - 1)/50
1/u = 1/50
u = 50 cm
So then, we can conclude that the size of the image is 50 cm
