By Newton's 3rd law: That for every action there is an equal and opposite reaction.
So if force on one mass is 4N, then the force on the other mass is -4N.
<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
given,
mass of the steel ball = 35 g = 0.035 kg
the horizontal distance is
( v cos θ ) t = 4.8..........(1)
the vertical distance is
...(2)
since,
..................(3)
using equation(2) and (3)
(v t)² (cos²θ+ sin²θ) = 4.8² + 4²
(v t)² = 39.04
t = 0.76 s
the speed is
vt = 6.25
v × 0.76 = 6.25
v = 8.22 m/s
Answer: Nature
Explanation: “nature” refers to biological/genetic predispositions’ impact on human traits, and nurture describes the influence of learning and other influences from one’s environment.
Answer:
These energy exchanges are not changes in kinetic energy. They are changes in bonding energy between the molecules. If heat is coming into a substance during a phase change, then this energy is used to break the bonds between the molecules of the substance. The example we will use here is ice melting into water.
Explanation:
