Stocks/bonds. High risk high yield compared to savings
Answer:
It reduces strength.
Explanation:
It not desirable to produce concrete mixtures of a higher consistency than normal because the strength of the concrete decreases. Consistency plays an important role in the determination of strength of concrete. Less water than normal quantity in concrete increases the consistency but decreases strength due to incomplete chemical reaction while on the other hand, adding more water would increase water-cement ratio and reduces consistency as well as strength of the concrete so that's why necessary amount of water and cement should be added to get higher strength.
Natural changes to the ecosystem refer to environmental phenomenon that occur naturally. Natural changes include floods, volcanic activity, hurricanes, droughts, and earthquakes. They can be destructive, but they also have advantages.
The benefit of the flood is for example providing nutrients to the soil that were lacking. Also t<span>here may be relocation of fishes and organisms living in water bodies, which improves the ecosystem.
Volcano threatens t</span>he people and animals in the area are threatened, but is has also some advantages, for example:<span>the soil becomes rich due to the nutrients from the volcano.
</span>Hurricanes result in the destruction to infrastructure and loss of lives, vegetation, and livestock. The advantage is that it lowers the temperature and t<span>he wind will cause the topsoil to be distributed to areas in which it was lacking.</span>
The aggregate demand can be increased by decreasing the prices and increasing the supply of goods and services for which the supply of goods and services has been increased by optimum utilization of current inputs.
<h3>What determines output withinside the short run?</h3>
In figuring out how much output to supply, the organization's goal is to maximize profits situation to two constraints: the consumers' demand for the organization's product and the organization's expenses of production.
Consumer demand determines the price at which a perfectly competitive organization might also additionally sell its output.
Thus, The aggregate demand can be increased by decreasing the prices and increasing the supply of goods and services for which the supply of goods and services has been increased by optimum utilization of current inputs.
