Answer:
population pyramids
Explanation:
Population pyramids show the structure of a population by comparing relative numbers of people in different age groups.
Population structures differ markedly between Less Economically Developed Countries LEDCs and More Economically Developed Countries MEDCs.
The shape of a population pyramid can tell us a lot about an area's population.
Usually pyramids are drawn with the percentage of male population on the left and percentage of female population on the right.
It gives us information about birth and death rates as well as life expectancy.
Answer:
C. supply and demand
Explanation:
<u>In the system of the market economy, the decisions about economic processes are based on the of the people (how much they need and buy something) and the needs of the supply (needs for natural resources, goods, and things which can be bought). </u>
A market economy also means the pricing of the goods is based on the demand for them. If products are not in demand and bought by the customers, it’s the price and supply goes down. Once the demand for the product grows, the profit is made.
The final goal is the price which is <u>equilibrium</u>, meaning goods are supplied exactly by the demand and with the fixed price that makes the process possible. This equilibrium should also provide the profit for the supplier.
Answer:
they do orbit the sun but they are farther away, they are very small, the dwarf planet Pluto is around the size of a moon, and I wouldn't say they have a clear path because dwarf planets don't normally have a clear path... they are normally around or are inside the outer asteroid belt of a solar system
Eₖ = √1/2 mv²
Eₖ/v² = 1/2 m
2Eₖ/v² = m
mgh = 1/2 mv²
gh = 1/2 v²
2gh = v²
v = √2gh
= √2 × 10 N/kg × 2 m
= 6.324 ms⁻¹
m = 9.8/(6424)²
= 9.8/39.993
= 0.245 g
I am not sure if it's correct.
i transposed for m in the first equation then to find the velocity I combined the potential and kinetic energy equation. there was no mass because velocity doesn't depend on the mass
Then I used earth's gravitational field strength (g) 10 N/kg and the 2 m was the height provided in the question
you can try working and see if you get the same
