Economics is the study of producing and consuming goods and services.
Economics show the GDP, or Growth domestic product, which show if a country is making more and intaking less products compared too others. The higher the GDP, usually (unless consumption is great too), the more built up the country is.
hope this helps
Every piece of matter begins “Out of this world”
f = 10000N
distance moved = 20 m
work done = 10000*20 = 200000
The quantity can be work or kinetic energy or potential energy. Work is same as the energy.
Work done can be described as energy transferred from and object when a force is applied along a displacement. That is work done is the product of force in the direction of the displacement and the magnitude of the displacement.
Mathematically it can be represented as,
W = F x d
where,
W ⇒ work done
F ⇒ force acting along the displacement
d ⇒ magnitude of displacement
We know,
force = mass x acceleration
∴ the unit of force is kgms⁻²
The unit of work done will be kgms⁻² x m
That is kgm²s⁻²
where m is the unit of displacement that is meter (m)
Hence kgm²s⁻² is the unit for work or energy

Remember that the left is NEGATIVE
and RIGHT is POSITIVE
16. +3N - 6N = -3N
therefore 3N to the left (because left = -)
17. +5N - 5N = 0N , zero resultant force
18. +6N - 4N = +2N
therefore 2N to the right (because right = +)
