Answer: Option B.
Strong nuclear force Gravity.
Explanation:
Nuclear force is the strongest force while Gravity is the weakest force. Strong nuclear force is the strongest force because it's act and hold atoms of matter together. It also binds neutrons and protons together to form atomic nuclei and it's has strength of 1.
Gravity is considered the weak force out of the four fundamental forces because it has a very small strength of 10^40 than electromagnetic force.
Answer:

Explanation:
As we know that there is no external torque on the system of platform, banana and the monkey
so the angular momentum of the system will remains conserved
so here we can say


here we know that





Now from above equation



Answer:
0.95 seconds
Explanation:
t = Time taken
u = Initial velocity = 15 m/s
v = Final velocity
s = Displacement
a = Acceleration = 9.81 m/s² (downward positive, upward negative)
Time taken by the ball to reach the maximum height

Maximum height

Distance between maximum height of the ball and the branch is 11.47-7 = 4.46 m
So, the distance that will be covered on the way down is 4.46 m
Now
u = 0
s = 4.46

Time taken by the ball from the maximum height to the tree branch is 0.95 seconds.
Total time taken from the moment the ball is thrown to reach the tree branch is 1.52+0.95 = 2.47 seconds
