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
People learn to empathize feelings of other people by putting them self’s in the other persons show to try to see what there going through in life. We can improve by starting to not focus only on your self and to start you can help other people around for example a family member.
involves hormones- The patch delivers hormones that stop an egg from being produced.
forms a barrier- Condoms keep semen with sperm from reaching the vagina.
involves use of spermicide- A diaphragm blocks sperm from the cervix, and spermicide slows movement of sperm.
protects against STIs- Condoms help keep partners' body fluids from coming into contact.
the most effective method- Abstinence, if total and continuous, is 100 percent effective against pregnancy and STIs.
