Concept :- </h2>
The plane mirror has flat reflecting surface and the angle of reflection is always equal to the angle of incidence. The image formed by a plane mirror is located in front of the mirror but appears to be formed behind the plane in which the mirror lies. To find the nature of the image formed by a plane mirror. We need to study the reflection through a plane mirror.plane mirror has flat reflecting surface and the angle of reflection is always equal to the angle of incidence.

<h2>
Required Answer :- </h2>
→ image formed by a plane mirror is : <u>virtual, behind the mirror and of the same size as the object</u>
<h2>Additional information :-</h2>
- Plane mirrors are the only type of optical mirror for which a real object produces an image that is virtual, erect, and of the same size of the object. The virtual objects produce a real image. The focal length of a plane mirror is defined as infinity, and its optical power is zero.
- The image formed by a plane mirror is erect, laterally inverted, and of the same size as that of the object. The left side of the object appears on the right side of the image. Also, the distance of the image from the plane mirror is same as the distance between the plane mirror and the object.
- Plane mirrors are used as looking glass.
- Plane mirrors also have many scientific uses. In most of the measuring instruments, a plane mirror is placed under the scale and pointer. When the pointer moves, the image in the plane mirror also moves.
- Now the eye is so placed that the pointer covers its own image, and thus the pointer and its image coincides. Thus the eye, the pointer and its image in the mirror are in the same line perpendicular to the scale. This helps in getting the correct reading.
- Plane mirrors are also used in constructing periscope which is used in submarines.
- Plane mirrors are used in solar cookers.
- Plane mirrors are used to make kaleidoscope, a toy which produces beautiful patterns from colored paper, pieces of glass or small colored beads.

Answer:
There are 5 significant figures in 52.887
5, 2, 8, 8, 7 --> all of these numbers are considered significant.
Answer:
200,000 joules <3
Explanation:
just accept it
Answer:
r = 78.95 m
Explanation:
given,
Person Walk in east, r₁ = 45 m
Then he walk, r₂= 39 m in the direction of 40◦ North of East.
writing the total displacement in x- direction
r₁ₓ = 45 m
r₂ₓ = 39 cos 40°
r₂ₓ = 29.87 m
total displacement in x-direction
rₓ = r₁ₓ + r₂ₓ
rₓ = 45 + 29.87
rₓ = 74.87 m
displacement in y-direction
r_{1y} = 0 m
r_{2y} = 39 sin 40°
r_{2y} = 25.07 m
total displacement in y- direction
r_y = 25.07 m
using Pythagoras theorem for the magnitude calculation
r = 78.95 m
The magnitude of total displacement is equal to 78.95 m.
We have that a blackbody radiator either constantly absorbs energy or constantly emits energy, depending on its surroundings. In this case, the energy is continuously and smoothly decreasing, thus it cannot be like B and C.
The energy loss or gain is also monotonous, it has the same direction; a radiator cannot gain energy at some point and then lose some. Hence, it does not resemble a wave either. The most appropriate model is the ramp. Energy is constantly emitted to surroundings and it decreases monotonically.
