Answers
Rotation around a fixed axis or about a fixed axis of revolution or motion with respect to a fixed axis of rotation is a special case of rotational motion. The fixed axis hypothesis excludes the possibility of an axis changing its orientation, and cannot describe such phenomena as wobbling or precession.
angle which an incident line or ray makes with a perpendicular to the surface at the point of incidence.
Explanation:
1)Rotation around a fixed axis or about a fixed axis of revolution or motion with respect to a fixed axis of rotation is a special case of rotational motion
2)In optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal
3)The vibrational or stress waves in elastic media, having a frequency below those of sound waves that can be detected by the human ear—i.e., below 20 hertz
4)Electroplating is the process of coating a metal with a thin layer of another metal by electrolysis to improve the metal's resistance to corrosion. Iron articles are electroplated with copper, chromium, tin or nickel for decthe emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.orative purposes in jewellery, and for the durability of cutlery and motor parts.
5)The emission of energy as electromagnetic waves or as moving subatomic particles, especially high-energy particles which cause ionization.
