Answer me fast i will mark you brilliant ​

Answer 1

Explanation:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Answer 2

Answer:

58

Explanation:

given mass of Mg is equal to 24

molecular mass of Mg(OH)2= 24 + 16 ×2 +1 ×2

= 24 + 32 + 2

= 58

16 is mass of oxygen(O) and 1 is mass of hydrogen(H) and since O and H both are inside the bracket so both will be multiplied by the subscript 2
