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.
Answer:
How did Congress organize the executive branch of the newly formed United States in 1789? It set up four departments to carry out different tasks. ... The US had trouble borrowing money to pay its debts.

<span>The federal government collects income taxes in installments rather than waiting until the end of the year for a variety of reasons. The primary reason is for cash flow purposes. The government's cash expenditures are ongoing throughout the course of the year so in order to manage cash flow to allow for payment of the expenses they need periodic inflows as well. This is the practical purpose for the installments. Failure to have periodic cash flows to match periodic expenditures would also result in the need for heavier short term borrowing which would further increase expenditures in the form of increased interest incurred. Cost savings is therefore a second reason.</span>
Answer: D. Fifty-four forty or fight
Explanation:
The rallying cry “54–40 or fight!” became popular among Democrats. Polk wanted territory, not war, so he compromised with the British Foreign Secretary, Lord Aberdeen. The Oregon Treaty of 1846 divided the Oregon Country along the 49th parallel, as in the original US proposal.
