Anyone know a simple way to describe friction not the definition online, just what you think Subject: Science but i did chemistry cuz therewas no scienece

the resistance that one surface or object encounters when moving over another.

Explanation: :D

Answer/Explanation:

Friction is tension between to objects or people that are moving in opposing directions or with opposing ideas. Friction decreases motion overtime and it also creates thermal energy from kinetic energy. In both relationships and objects, the friction wears down both sides depending on the roughness, strengths, and characteristic of each side.

a. the law of proportion states the combination of 2 atoms in a specific ratio to produce multiple compounds such as the given statement of question ‘1st compound contains 88.8 % cu ’ indicates 88.8 g of cu is present along with 11.2 g oxygen in 100 g of compound whereas the statement ‘2st compound contains 79.9 % cu ’ indicates 79.9 g of cu is present along with 20.1 g oxygen in 100 g of compound

1st compound contains 88.8 g cu

for cu

m = 63 g /mol

atomic % = 88.8 /63 = 1.42

for o

m = 16 g /mol

atomic % = 11.2 /16 = 0.7

b. the emperical formula of 1st compound is

cu1.4o0.7
