F = mass of object X acceleration

The unit of Force is Newton (N)

unit of acceleration is ms⁻²

unit of mass if Kg

[all these are SI units]

Mass of object =\frac{Force}{acceleration}

mass of sprinter =\frac{650}{10}=65kg

Which best describes why a liquid needs a container when a solid does not?Solids fill their containers, and liquids have definit
Rina8888 [55]

The correct answer choice which best describes why a liquid needs a container when a solid does not is simply because:

Solids have definite shapes, and liquids fill their containers.

Matter is classified as element, compounds and mixtures

<h3>What is an element?</h3>

An element is a substance which cannot be split into simpler forms by an ordinary chemical process. This simply goes to say that elements are substances which cannot be decomposed into simpler substances by ordinary chemical reactions.

An atom is the smallest unit or part of an element which can take part in a chemical reaction.

On a general note, elements are classified as thus:

  • Metals, non-metal, and metalloid.

  • The extreme left side elements in the periodic table are metals, for example, aluminum, sodium, calcium, caesium, etc.

  • However, elements on the right side are generally referred to as non-metals, carbon, chlorine, oxygen,

So therefore, the correct answer choice which best describes why a liquid needs a container when a solid does not is simply because:

Solids have definite shapes, and liquids fill their containers.
