What type of mirror do dentists usually use to clearly see the images or our teeth? why?
2 answers:
The dentists make use of the Concave Mirrors to obtain the clear and magnified image of the teeth.
Further Explanation:
The dentists need to obtain the clean and magnified image of the teeth while operating or examining the teeth. The mirror is held by the dentist very close to the teeth so that the image could be as clear as possible.
Since the mirror is placed very close, the object for the mirror i.e. the teeth lies at the distance almost less than that of the focal length of the mirror. Now the mirror held by the dentist should be such that it forms the magnified and erect image of the object placed between the focus and the pole of the mirror used by the dentist.
<u>Image Formation:</u>
The erect and magnified image for the object placed at the distance less than the focal length of mirror is only formed by the concave mirror. A concave mirror forms a virtual, magnified and erect image of the teeth so that the dentist can have a clear look at the teeth.
The ray diagram for the image formation of the teeth by the dentist’s concave mirror is attached below:
Examples:
The concave mirror is used in several other applications where it is used to disperse the light incident on it and form a magnified image.
• The concave mirrors are used in the headlights of the vehicles in order to reflect the light and form a strong beam of light by focusing the light after reflection.
• The concave mirrors are used as the mirrors to form the large magnified images of the object to view them clearly. For ex: the shaving mirror, a dentist’s mirror etc.
Thus, the dentist uses a concave mirror in order to obtain the clean and magnified image of the teeth.

Average speed is the ratio of total distance moved by Chi in total time interval
So here we will have
Total distance = 100 m + 400 m
Total time taken = 5 min + 15 min = 20 min
now by the formula of average speed we know that
so average speed will be 1.5 km/h
Answer:
x_{cm} = 4.644 10⁶ m
Explanation:
The center of mass is given by the equation
= 1 /
∑
Where M_{total} is the total masses of the system, is the distance between the particles and
is the masses of each body
Let's apply this equation to our problem
M = Me + m
M = 5.98 10²⁴ + 7.36 10²²
M = 605.36 10²² kg
Let's locate a reference system located in the center of the Earth
Let's calculate
x_{cm} = 1 / 605.36 10²² [Me 0 + 7.36 10²² 3.82 10⁸]
x_{cm} = 4.644 10⁶ m
