Answer:
Nuclear fission of U235 to Kr92 and Ba 141.
Explanation:
Nuclear fission is the spantenous disintegration or breaking down of a big atom into smaller nucleus with the release of huge amount of energy. It involves the artificial transmutation of a heavier nucleus by bombardment with other rasuiactive particles.
Answer:
2.03873 s
70.38735 m
4.07747 seconds
5.82688 seconds
27.37482 m from the ground
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s² = a
time needed for the ball to reach its maximum height is 2.03873 s
The time taken to go up and the time taken to reach the point from where it was thrown is the same.
So, time needed for the ball to return to the height from which it was thrown is 2.03873+2.03873 = 4.07747 seconds
The maximum height the ball will reach is 50+20.38735 = 70.38735 m
Time needed to reach the ground is 2.03873+3.78815 = 5.82688 seconds
The time from the maximum height that is required is 5-2.03873 = 2.96127 seconds
The ball will be 70.38735-43.01253 = 27.37482 m from the ground
