Three reasons why friction is needed

Chemistry
1 answer:
ivanzaharov [21]3 years ago
3 0

Answer:

1:Without friction, we would not be able to stop walking since we would just keep slipping like on ice.

2:Without friction, objects would just slip and fall with a simple blow of air

3:And finally, without friction, we wouldn't be able to use machinery like cars and etc since they would just fly off

Explanation:

Friction can be a useful force because it prevents our shoes from slipping on the pavement when we walk and stops car tires skidding on the road. When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding. Sometimes we want to reduce friction.

taurus [48]

The same

Explanation:

If a liquid substance is transferred to a different container, the volume of the liquid in the new container will remain the same.

The volumes of liquids are fixed and does not change. Wherever they are contained, just like solids, they maintain their constant space.

  • Volume is the amount of space occupied by a body.
  • Gases do not have fixed volume as they fill their containers and they take up the shape.
  • Solids and liquids have a fixed volume.
  • They do not change their volume.

Which is the most accurate description of compounds?
baherus [9]

Answer: c.They have a unique set of properties that can be used as identifiers.

Explanation:

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

Compounds can be decomposed into simpler constituents using chemical reactions.

Example: Water (H_2O)

2H_2O\rightarrow 2H_2+O_2

Compounds have different properties than the elements it is made up of.

Thus the most accurate description of compounds is that they have a unique set of properties that can be used as identifiers.
