(According to me and certified experts) Transverse wave.

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.

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:
-322.64 J
Explanation:
75 N * cos 125 * 7.5 = -322.64 J
Answer:
Explanation:
When a body is in circular motion, the centripetal force acts towards the center of the curvature of the path. It is required to keep the object in circular motion. The velocity acts in the tangential direction to the curvature and when the centripetal force is removed it threads that path
Hello!!
For calculate the velocity let's applicate the formula:


d = Distance = 4000 m
v = Velocity = ?
t = Time = 400 s
⇒
