Answer:
Potential energy in the coal gets transformed to electricity
Explanation:
- As when coal has burned the conversion of the energy takes place and the chemical energy in coal s converted into the electrical energy and thus heat is produced an is used to run the steam power engines.
- So as the heat energy derived from the coal is converted to kinetic and kinetic is converted to mechanical and this mechanical is coveted to electrical energy to further run the machines thus energy is not destroyed it only transfers.
Answer:
Mt. Kenya is a large fairy symmetrical volcanic cone. Its diameter at the base averages 120 km. It was formed between 2.6 and 3.1 million years ago by eruptions of successive layers of lava and agglomerates from a central vent in the earth's surface.
The income elasticity of demand for bagels is 0.48. Bagels is a normal good. Income elasticity of demand for donuts is -0.31. Donuts is an inferior goods.
<h3>
What is income elasticity of demand?</h3>
Income elasticity of demand measures how the quantity demanded of a good changes when there is a change in income. Inferior goods have a negative income elasticity. Normal goods have a positive income elasticity.
Income elasticity of demand = percentage change in quantity demanded / percentage change in income
Income elasticity of demand for bagels:
percentage change in quantity demanded = (10 /6) - 1 = 0.667 = 66.7%
percentage change in income = ($6000 / $2500) - 1 = 1.4 = 140%
Income elasticity of demand = 66.7 / 140 = 0.48
Income elasticity of demand for donuts:
percentage change in quantity demanded = (8/14) - 1 = -0.429 = 42.9%
percentage change in income = ($6000 / $2500) - 1 = 1.4 = 140%
Income elasticity of demand = -42.9/ 140 = -0.31

If we have a dark colored, coarse soil and reddish smooth soil for comparison, we can find lots of differences in them.
- The dark soil will have bigger layer of humus, while the reddish one will have a very small almost unnoticeable layer of humus.
- The color differs a lot, while the dark soil will have a dark brownish color, the reddish one will have intense orange-red color.
- The vertical profile of the soils will differ a lot; the dark one will have much bigger top two layers, while the reddish one will have very small upper layers and dominant middle layer.
- The dark soil will be rich in biomass, while the reddish one will be rich in iron and clay.
