Since Southern blacks were not allowed to fight in the Civil War, they were able to contribute to the war effort by joining the army despite the rules against it. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
(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>a = mB g / (mA + mB) </span>
<span>= 7.0 * 9.81 / (11.0 + 7.0) </span>
<span>= 3.815 m/s^2 </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>
<span>= sqrt(2 * 1.250 / 3.815) </span>
<span>= 0.810 sec to 3 sig. fig. </span>
<span>(c) </span>
<span>From (1): </span>
<span>(mA + mB)(a / g) = mB </span>
<span>mA(a / g) = mB(1 - a / g) </span>
<span>mA = mB(g / a - 1) </span>
<span>= 4.0(100 - 1) </span>
<span>= 396 kg.</span>
On October 9th, 1773 James Boone and a small group if settlers set up camp on the way to Kentucky. That morning, they were attacked by Delaware, Shawnee, and Cherokee Indians.
The correct answer is There was an increased enthusiasm for religion.
After the end of WWII, Americans joined churches and synagogues in record numbers. Increasing not only the number of attendance but also the demand for books, songs, and movies with a religious tendency. The other reason that increased the enthusiasm for religion was the Cold war, where the Communism was depicted as an anti-christian movement mastered by Satan. In 1954, Congress added the phrase “under God” to the Pledge of Allegiance and in 1956 made the statement “In God We Trust” mandatory on all coins and currency. In 1956, Congress made “In God We Trust” the national motto.
