Answer:
The correct answer is option d.
Explanation:
Fusion :It is defined as nuclear reaction in which two or more than two small nuclei combine together to form a large nucleus.
For example:
Fission :It is defined as nuclear reaction in which a large nucleus of an atom splits into two or more than two small nuclei is known as a nuclear fission.
For example:
is a nuclear fission reaction.
The type of reaction shown in the figure demonstrates the process involved in nuclear fusion by binding together two nuclei.

Answer:
B) t = 1.83 [s]
A) y = 16.51 [m]
Explanation:
To solve this problem we must use the following equation of kinematics.
where:
Vf = final velocity = 0
Vo = initial velocity = 18 [m/s]
g = gravity acceleration = 9.81 [m/s²]
t = time [s]
Note: the negative sign in the above equation means that the acceleration of gravity is acting in the opposite direction to the motion.
A) The maximum height is reached when the final velocity of the ball is zero.
0 = 18 - (9.81*t)
9.81*t = 18
t = 18/9.81
t = 1.83 [s], we found the answer for B.
Now using the following equation.
where:
y = elevation [m]
Yo = initial elevation = 0
y = 18*(1.83) - 0.5*9.81*(1.83)²
y = 16.51 [m]
