According to a recent study the positively charged atmosphere attracts negatively charged spider silk might the electrostatic force play in spider
dispersal.
3)The positively charged atmosphere attracts negatively charged spider silk.
<u>Explanation:</u>
The ballooning of spiders can be explained by the electrostatic interaction between spider silk, atmosphere and the earth. Spiders lack the ability to fly but still they move in the air by discharging silk and moving easily using it. Air drag also plays an important role in the movement of spiders but ballooning effect cannot be just explained in terms of air drag.
The earth is negatively charged and thus any ground based object will have this negative charge. Spider silk is negatively charged. Thus there will be an electrostatic repulsion between any ground based object and the spider silk. Similarly the atmosphere is positively charged which means there will be an attraction between the spider silk and atmosphere.
<span>1. John Locke's part in the American Revolution: His ideas influenced America's founders. Locke's Second Treatise on Civil Government (1689) expounded on ideas of government created by the people and for the people.

Locke argued for the idea that the people are utlimately the source of authority in governing, and that decisions made by the majority of people are to determine what the laws are. Locke wrote: "When any number of men have, by the consent of every individual, made a community, they have thereby made that community one body, with a power to act as one body, which is only by the will and determination of the majority."</span>

Answer:
How did farming lead to new types of economic activities? A steady food supply and food surplus meant all people didn't have to farm. Some people became skilled workers who produced goods. What are the advantages and disadvantages when a community grows?
