A História é uma ciência humana que estuda o passado. Ela é importante para conhecermos os fatos históricos e sabermos interpretá-los para conhecer melhor
(a)
<span>Let: </span>
<span>a be the acceleration of the system, </span>
<span>g be the acceleration due to gravity, </span>
<span>T be the tension in the string. </span>
<span>For mA: </span>
<span>T = mA a </span>
<span>For mB: </span>
<span>mB g - T = mB a </span>
<span>Adding to eliminate T: </span>
<span>mB g = (mA + mB)a ...(1) </span>

<span>= 3.82 m/s^2 to 3 sig. fig. </span>
<span>(b) </span>
<span>Let: </span>
<span>s be the distance to the edge of the table, </span>
<span>t be the time taken. </span>
<span>s = at^2 / 2 </span>
<span>t = sqrt(2s / a) </span>

Answer:
Similarities between the Know-Nothing Party and the Response to the Red Scare of 1919
1) Both called for equal rights for women and African Americans:
b. False
2) Both sought to limit immigration to the United States:
a. True
3) Both supported the overseas expansion of the United States:
b. False
4) Both attempted to limit the influence of big business on American politics:
b. False
Explanation:
The Know-Nothing Party in the 1850's was a clandestine nativist organization that later formed the American Party. This political party, according to britannica.com, "called for restrictions on immigration, the exclusion of the foreign-born from voting or holding public office in the United States, and for a 21-year residency requirement for citizenship."
On the other hand, the response to the Red Scare of 1919, the first Red Scare described the fear of communism and anarchism during the cold war between Russia and the United States. In the response to the Red Scare of 1919, there were calls for immigration restrictions and purging of the Russian Communist influence in the United States.
Conclusively, both sought to limit immigration to the United States.
