<u>T</u><u>he area w</u><u>h</u><u>ich touches the sand floor of 4 feet of the bull is less than the man.</u>
because the area of surface of contact is more in bull than in man. More is the area of contact, leads is the force or pressure affected.
Electrons need specific amount of energy to jump levels and to emit energy
Answer:
Option C
Solution:
As per the question:
Velocity of the jet, v = 600 m/s
Acceleration, a = 4.0 g
Now,
To calculate the radius of curvature:
The necessary centripetal force on the jet is given by the force:
(1)
where
= centripetal force
where
m = mass of the jet
R = radius of curvature of the path
Using eqn (1):

Thus


where
g = acceleration due to gravity = 


R = 9183.67 m ≈ 9200 m
