<span>The answers are the second and fourth choices. Although the majority of Americans during that time, including the President of the United States (McKinley), wanted to avoid war and hoped to settle the Cuban question by peaceful means, a series of events early in 1898 strengthened U.S. feelings against Spain. The first was the publication by Hearst of a stolen letter (the de Lôme letter) that was written by the Spanish minister at Washington, wherein the diplomat expressed contempt for McKinley. This was followed by the sinking of the U.S. battleship Maine in Havana harbor on Feb. 15, 1898, with a loss of 260 men. Although Spanish involvement was not proved, U.S. public opinion was aroused and war sentiment rose. The call of the advocates of war was further strengthened as a result of eyewitness reports by members of the U.S. Congress on the effect of the reconcentrado policy in Cuba.</span><span>

Answer:
Centripetal acceleration does not change speed but it changes direction as it is a single thing moving in a circular path. Most accelerations, like linear acceleration, cause things to move in a straight line. But, both centripetal and angular acceleration are vectors.
Answer:
741.333
Explanation:
F = ma
so in order to find mass you must change the equation to
m = F/a
m = 5560/7.5
741.333 = 5560/7.5
The force acting on the object is constant, so the acceleration of the object is also constant. By definition of average acceleration, this acceleration was
<em>a</em> = ∆<em>v</em> / ∆<em>t</em> = (6 m/s - 0) / (1.7 s) ≈ 3.52941 m/s²
By Newton's second law, the magnitude of the force <em>F</em> is proportional to the acceleration <em>a</em> according to
<em>F</em> = <em>m a</em>
where <em>m</em> is the object's mass. Solving for <em>m</em> gives
<em>m</em> = <em>F</em> / <em>a</em> = (10 N) / (3.52941 m/s²) ≈ 2.8 kg
