an image formed by a mirror is virtual, upright, the same size as the object, and the same distance from the mirror as the object. which mirror produced the image? a. flat mirror b. concave mirror c. convex mirror d. spherical mirror

The correct answer is Option A.

Explanation:

From the given options:

1. Flat mirror: This type of mirror is also known as plane mirror. The nature of the image formed by these mirrors is that the image is always virtual, upright, same as the size of an object and is formed at the same distance from the mirror as that of an object.

2. Concave mirror: This is a type of spherical mirror which has reflecting surface present on the inside region. The image formed by these mirrors can be virtual and upright or real and inverted. Size of the image depends on the position of the object from the mirror.

3. Convex mirror: This is a type of spherical mirror which has reflecting surface present on the outside region. The image formed by these images is always virtual, erect and of smaller size.

4. Spherical mirror: There are two types of spherical mirrors: Concave mirror and convex mirror.

Hence, the correct answer is Option A.

double the distance = divide strength by 4

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
