When sound falls on the sofa, fluffs and other light substances such as clothes, papers, thermocol, coating of plaster of paris, carpets, curtains, furniture, wood etc., they absorb the sound to a good extent. These are called good absorbers of sound.

PLEASE MARK AS BRAINLIEST ❤️✨✨

Generally, soft, pliable, or porous materials serve as good sound absorber.

We can also make other materials to absorb more sound by making it zigzagged.

Examples are clothes, curtains, acoustic foam, blanket, sofa etc.

Answer:

answer of first question:-An indirect method to determine the absolute mass of an atom has been devised. The mass of a particular atom is taken as a standard unit and the masses of other atoms are related to this standard. Hydrogen being the lightest element and being the smallest atom was chosen and assumed to have a mass of 1. An atom of hydrogen was assigned an atomic mass equal to one atomic mass unit (a.m.u). The number does not signify the mass of an atom in grams. It is just a pure number. The masses of atoms of other elements were compared to that of hydrogen, in order to find their atomic mass relative to it. If one atom of sulphur weighs as much as 32 atoms of hydrogen, then the relative atomic mass of sulphur is 32 a.m.u.
